Basically astrology. I got this app because someone said it was science based. It’s not. It doesn’t have any references to science in it. The first leap didn’t fit my baby at all, and the second leap only fit my baby for a couple of things on the list, which was probably just a coincidence. The app’s texts explaining the leaps are like long rants which are difficult to apply to actual behaviors that my baby has. And, once again, there’s no scientific evidence of any of it. The app also has some pop ups which are annoying to click away when exploring the app. I’m sorry I paid for this app. It’s basically astrology, trying to explain all babies based on due dates. Babies don’t follow the calendar. The worst thing is that the app gives a false sense of “light at the end of the tunnel” and directs attention away from real issues that a baby has.

First time mom!. As a first time mom, sometimes you're just wondering if you’re doing everything right. Especially when it comes to learning. I didn’t know anything about development leaps! Thanks to a mom of 5 showed me this app. And I’m grateful thankful for that. Now I understand what’s going on and I know how to help her through her leaps and what she should be at least learning. We’re now in leap 7 and her personality really does change. I am super grateful for this app and would recommend it to my new mommy friends. Also I love the new update! It has this very clan organized look. But, I really do miss the countdown of how many days are left in her leap and the countdown to her next leap.

Second Time Dad Dissapointed. This app is supposedly anchored in groundbreaking research. I haven’t read the book, but if the app is indeed designed to go “hand in hand” with the book then it really needs to say that more up front. In fact, it’s hard for me to understand why you would need an app if you had the book. The app is practically incomprehensible as it is. The checklists are condescending. Parts of the app say “leaps can occur plus or minus two weeks from what the calendar shows”. Then when you’re two weeks out and checking all the boxes the app condescends to say “your baby isn’t experiencing everything you just checked off”. Oh freaking really? Seems like a fancy digital way to get railroaded into some educational baby reading, like a 4th trimester version of all the cute little “here’s what your baby looks like now!” notifications you get in the pregnancy trackers. You finally reach the first leap, weeks after your baby is fussier, clingier, more alert, needing to be held, all the symptoms, and find out “hey, your baby is different now” in these two ways with some 30 second videos? Honestly it’s a waste of my time. I’d rather read a blog post each leap and be done with it.

Hate the new update. I absolutely loved this app so it is hard to rate because I hate it now. I recommend to everyone. It was perfect! I liked how it told me what things my baby might be going through and why he was going through it as well as the new things your baby might be doing now. Now it is more of a diary where you tell the app what is going on. It still gives tips on activities you can do to help with the new development but overall we hate the new update. Luckily we have an iPad where the update didn’t happen and we use that to see what’s going on. Luckily he only has a few leaps left. I would Not recommend this new updated version. Especially having to pay for the app. If you want a journal that documents when your baby cries more often then this is for you.

I wanted to like this. I had been using for the past few weeks and really liked. Then today I tried updating the diary and it crashed every time I tried to save. I restarted my phone and then tried deleting the app so I could restart. It completely wiped everything I had been documenting for the past two weeks. I don’t even feel like starting over I’m so upset. I also hate that every time I took notes in the diary it would move me to the top of the page instead of where I left off. The napping page if you moved your finger the slightest bit just moved you to the next page so you had to start all over if you didn’t get the time right. The leaps have been somewhat accurate but I don’t know that it’s worth the $4. And now that all my data and memories from those two weeks are gone I don’t think I’ll continue using. Very disappointed.

But the app, not the subscription. The app is great, very helpful even with my third baby. But the additional features at $2.99/month are not worth it and should just be included in the app itself. Unless you’re going to use the monitor feature, which seems cool if you haven’t actually bought a baby monitor, the other extras are marginal added value. The white noise was alluring but not functionally useful because they run for only a few minutes and then stop. Even if you click the “continual sound” option, it pauses briefly every few minutes and then restarts- which wakes both me and the baby due to the absence of what should be helpful white noise!! It’s nice to have the audio book in the extras, but I chose the app over the book for a reason and could get it from the library for free or from Audible for less than $2.99/month.

General information presented in a convoluted way. Not sure why this is such a highly rated app but something must have changed drastically since then. The app reads like an essay on general brain development steps that happen from birth and on. The only personalization it does is use your baby’s gender pronouns and to make some random chart about when your baby will be fussy based on his/her due date. I say it random because it was not accurate for me and seemed to be randomly created. The information is laid out like reading an article published in a scientific journal and information for a current milestone is split between different obscure sections— not what I want from an app. If I’m reading about today’s leap, why do I have to scroll (all the way) back to the top, click the “more” link, then click the second tab under that to read more on the associated milestone for today?? Put all of the info for today’s milestone on the same page! I want quick reads presented in a super coherent and attractive manner. But their content is so blah and general. I get the same salient points in a more straightforward fashion from my pediatrician and from the pregnancy tracker apps. I hate it. It hasn’t helped me at all. I wish I could get my money back. And I hope no one else wastes their money.

A Must-Have for all parents!. The Wonder Weeks app has been a great resource for this first-time mom. I especially love the tips and the list of possible new skills it provides for each leap. I know what activites are most helpful for my little man to develop all his new skills. The Sleep Schedule feature of the diary is very nice. One less thing I had to remember (when his naps occurred and how long they were). I learned very early how important sleep is to my growing little man. Lastly, having an idea when he might be more fussy because of a leap made me a little less confused when he cried. This App is definitely a must-have for all parents!

Wasn’t really worth it for me. Bought this app based on the glowing reviews here plus recommendations from friends and other people we know. It didn’t do much for us. I suppose we were lucky with our baby as his developmental leaps and fussy periods weren’t very disruptive. Because of that it was hard to tell how well the predictions of the app were. Also, a few other reviews talked about functions of this app being like homework, which I would agree. We stopped using it after a couple months. From a software perspective it looks and works very well. Some design choices for the interface perhaps could be improved as some screens are a bit unintuitive to get where you want to go. In the end, it’s hard to know if this app is for you until you buy and it then if it’s not then it’s money wasted. Keep that in mind before you hit the buy button.

Upset with new Update. So with the new update, this app because less ‘about you & your baby’ and more ‘about us as a company.’ What was once a; pay one fee and get all the app’s benefits, has become a; pay one fee to download, but then just kidding, we’re going to keep features from you until you SUBSCRIBE to a monthly plan. Parenting is already so expensive, so adding all these monthly subscription costs are ridiculous. Do companies not realize that we as consumers are adding them up? I get it, developing and updating apps is difficult, and a time consuming process, but the way this one changed and then didn’t address the previously paid users is super frustrating. I will be deleting and relying more on my TinyBeans app, which has always been more straightforward with their marketing strategy. We’re parents, not cash cows.

Every mom needs this app!. As a first time mom there were so many times my baby was having a rough week and I couldn’t figure out what I was doing wrong when suddenly I remembered this app and decided to check if we were in a leap. Each time I would find that we were, in fact, just entering one or right smack in the middle of a stormy week. Having that knowledge gave me the reassurance I need to know that I wasn’t doing anything wrong but also let me know that there was more I could be doing to help my baby through the current leap! It has made each leap so much easier for both of us! I also love that you can add more than one baby and I look forward to using it for any future children I have!

Great-Makes you want more. This app if great. I first purchased the book and ready parts of it. The book has more information, but most of it is parents’ experiences. While those are important, I feel that the most value giving by The Wonder Weeks is that provided by the chart. Those small little clouds can help you keep you sanity. Knowing that a leap is approaching or that you’re in the middle of one, helps you stay calm as a mother as it justifies the madness. The app provides the timing for the leap: by week and by dates. Also, the new feature adds it to your calendar which is GREAT! There is some information as of what to expect behavior wise. A bit more info about what each leap means for them and what to expect them to do. I recommend this app to all my mommy friends. It’s a great tool for a mom with one or 5 kids. I would have liked to see also an indication of growth spurts in the chart. Also, the chart ends at around 2 years I believe. While it is very beneficial to until that point, the kids still have major developmental leaps after (as I have witnessed with my own child). So, it would be great to add any information for after that. That just stays there and does nothing after... seems very close ended. Overall: it is great for when you need it, and you will need it for your own peace of mind when you don’t know why they keep crying and nursing.

My only parenting advice. I don't like to give a lot of parenting advice, but this app is one thing I tell every mom I know about. I'm on my 4th baby, and this app has been so dead on for us for every single child. I am so glad I found this with my first child because it has saved me from so much unnecessary anxiety, and most importantly allowed me to enjoy every part of my babies because I know the rough parts end. And thanks to this app I know almost exactly when they will end, lol! But seriously, prior to understanding what leaps were, I would think we were finally getting the hang of things, only to be wondering why my baby was suddenly so unhappy with everything he seemed to be happy with for weeks before. I wondered what I had changed, or what I was doing wrong. After I learned about leaps I understood that it wasn't about what I was doing, it was about what his brain was doing. I particularly love the alerts that warn you ahead of time that your baby is approaching a time when he might be more cranky than usual.

Great app to have as a New Parent. Absolutely loved having this app! Even our NICU baby’s Occupational Therapist was impressed with how accurate the timing of the leaps were and the recommend activities. Being a new parent you feel in the dark about a lot of things and this app helps give you some insight on your baby’s development, lets you prep for what’s to come- like when they may be fussy & clingy, and shows you what activities or things you can do to help tap into the latest thing your baby is learning. Highly recommend this app! We even used for our second child too.

Used to be great before update.... I have followed the wonder weeks with both of my kids. I was excited that the app provided a list of skills that you could see after a leap. However, they updated the app and completely changed the information. There is now an extensive list of signs your baby is going thru a leap (almost every behavior known to man is listed) but the list of skills learned after the leap is subpar at best. I guess they want you to pay for the ebook. Also the information is the same leap after leap. I wish I could have a refund as this app is now useless. I also read some of the developers responses to 1 star reviews, and I want to say that the information previously provided IS NOT still available in the app. The information available is mediocre and does not provide detail as it did before. Please change it back, or include the previously provided detailed information again.

Has helped me be a better mother. I’ve been using wonder weeks since my daughter was born. It’s helped me help my daughter thrive, as I understand where she is coming from and can see the world from her perspective. “Tantrums” or “fussiness” aren’t random, I am able to put myself in her shoes and understand why she is acting that way. It’s been super interesting to learn how her brain is developing as she grows. I can’t believe she is already in her last “leap”, it always felt so far away! But I will be using with my next who is due in March. I would highly recommend this to any parent with a child under 16 months. It changes your perspective of their behavior and I believe it has helped me be a better mother because of it.

Confused. I really like this app and would probably recommend it, but I’m a little confused. Why does it say for example a child has started a leap, specifically a leap that will start at 26 weeks when the child is only 22 weeks? I used my due date, but it’s like the chart start dates and the actual text content are not aligned. The same thing happened with the previous leap and it’s very confusing. Has she started the leap or is she going to start the leap four weeks from now?? Can anyone help me understand why these are consistently different? I should probably mention my due date and the actual birth are only one day different, so that clearly couldn’t be the reason.

Absolute Must!!!. Regardless of 1st or 3rd baby-you need this app!!! Gives the most detailed information/understanding of what the world is according to your little one. I often pondered the “what’s going on?” in terms of the disposition of my baby, and this app answered that question for me! If you need to anticipate the unexpected and changes that are happening, the Wonder Weeks gives the caregivers the peace of mind that we desperately desire. The ability to give yourself and the baby grace during the “stormy days” and with the timeframe, alerts, & checklists that are given, you are able to feel so much more confident in those days.

Helps me keep up with my Preemie. Very user friendly. I love the diary part and being able to add pictures. This really gives me a visual of how much my baby has grown physically and developmentally with skills. I can also show my baby’s physical therapist too so she can keep tabs on his progress and what we do at home. It helps you figure out activities to do with your baby which is really nice because I never know what good activities to do to help hone skills besides what our physical therapist gives us. Babies love variety though so the more activities the better. I have not used the nap time feature yet but I think I will now that babe sleeps through the night.

Good Resource, Poorly Redesigned. First off, I love the wonder weeks for helping explain baby’s behaviors as they grow and go through mental leaps. I love that it tells you what behaviors to typically look for and skills after each leap they master. I used the app with my first baby in 2018 and loved both the information provided as well as the layout of the app. It used to make it very easy to follow along with each leap. I was excited to use it with my second baby now but the new app format is not as user friendly as their old version. It makes it a little harder to follow along and the change in the flow of how the new version is written makes it confusing to keep up. It almost looks like the text was copy-pasted without being formatted. I still like that the calendar is there but miss the old format that was a lot more user friendly.

I love this app & highly recommend it to others!. This is my third child & I’m pretty educated on infant/child development, but this app has still been an amazing resource. I haven’t found any resource that gives the details that this app provides. I love knowing how my baby is currently experiencing the world. It doesn’t just tell you what skills your baby should be gaining but why they do the things they do just how they do them at that time. Like why their movements are so jerky, or why they stare at particular things. Why they make short abrupt sounds & then later how & why they start making longer smoother sounds. It has also been right on with the dates & the fussy vs bright periods. It’s nice to have a warning that baby is probably going to be fussy/clingy the next X # of days & when you can expect that period to be over as well. It’s honestly hard to describe just how awesome this app is & all that it does. I will continue to recommend it to those I know with infants.

An Essential Baby App. Especially when the child is your first, like ours, this little app is like having a pocket manual for your baby. It is especially useful when little one becomes inexplicably fussier. Why? Well, according to the Wonder Weeks (which is based on evidence-based medical science), this is usually because your child is going through one of the many ‘leaps’ of childhood. The app was incredibly accurate in predicting when (indicated by a rain cloud icon) our sweet one suddenly because much more sour. Knowing this was itself helpful since parents armed with this knowledge can fortify their emotional defenses in preparation. While some baby apps are fun - but do little in the way of informing parents - The Wonder Weeks stands out as the rare outlier which both satisfies our curiosity while respecting that our time for doing so is quite limited after baby’s arrival. I highly recommend it.

Mama T. Wonder Weeks was recommended to me by a friend at church. When my girl was 5 weeks old I was describing to my friend how she sometimes didn’t want to nurse or take long naps much anymore and she said it sounded like a Leap. Turns out all the things we were noticing were “signals” and she went through Leap 1. She’s 9 months now and just entered Leap 7, and some of the signals she’s already been showing way before now! I don’t live by this app or stay on it all the time, but it is helpful to know it’s not your fault when the babe gets a little fussier than normal. It just means they’re growing and learning like they should be:) we love looking at the list of skills and looking forward to her coming through with them on the other side. So fun:) God bless all you sweet parents, you’re doing a GREAT job and He gives grace to sustain ❤️

What’s so great? Why $4?. I downloaded this bc of the high ratings and hearing other moms talk about it. I feel like I’ve paid $4 just so that the app could tell me my kid is in a leap. There’s not much else that’s unique to the app that you couldn’t get from the Internet, and I’m not finding it to be very user-intuitive. The sleep diary function is buggy. I’m logging sleeps but it’s displaying them on the wrong day in the chart view. I’ll “check off” signs that she is displaying in the leap, but it doesn’t save them - so why even have the ability to check things off? Overall, I’d say if getting the peace of mind that your kid is just going through a phase is worth $4, then you should download. For me personally, that’s maybe worth $1 or could just be a free version of the app, and make people pay for the note taking and diary keeping functionality, which like I said is kind of buggy and confusing anyway. I’d like a refund.

Absolute must!!. I love this app. I heard about this early on when my son was first born so I tried it and man it’s extremely accurate. I find it fascinating being able to get a small glimpse behind your babies eyes. It really helps in understanding what they’re going through and why they might be more fussy than normal. It’s great for finding ways to stimulate your baby according to their development. It’s just overall wonderful and I feel so lucky to be a first time parent with resources like this. If we had nothing I think we would be even more emotionally shot not knowing why our baby is so unhappy sometimes. They’re just learning new skills!

Why did it change to subscription?. This app was great, I BOUGHT the app when my baby was born 6 months ago and it was soo helpful with info on what was happening in her little brain and how to help in the fussy stages. I honestly went to this app almost every week. Today I open it and to my surprise, the app which had already been paid for once, now became a subscription. I am very disappointed in this update decision, everything was already there, seeing as how I was able to read on future leaps, what’s the sub for now? It’s not like the leaps changed they are all still the same. Shame. At least have the decency to warn the app purchasers that there was going to be an update and that it would change the app to a monthly subscription, give us the choice whether to update and join the sub plan or stay on the old version which had already been paid for anyways.

The info is interesting, the app itself is confusing at times. It’s very cool that the app tells you what stage you’re baby is in. For the most part, I’ve felt like what they were saying is true. The tell you behaviors your baby might be displaying at a certain time, and it explains why they are doing it/what’s going on in baby’s brain. What I do NOT like is the format of the app. The information in the app is great & helpful (although I take everything with a grain of salt). But the app itself is confusing. To me, the app is not super intuitive or easy to use. I’ve had to figure it out by myself, but I shouldn’t have to do that. I think the app could really benefit from some changes that make it easier/more clear to use. It’s a shame because the information is really good, but it’s hard to figure out how to access all the information.

Great knowledge for any parent. I am a second time mother so I should know it all right? Wrong. My first is 10 and when he was a baby we didn’t have apps like this. It’s fascinating to read about the reasons behind your baby’s behaviors and also by knowing why your baby is behaving a certain way you can help them through all of their little growth spirts, while also helping yourself. Because let’s face it all parents wonder if their doing a good enough job so when baby is having an especially rough day we all say what am I doing wrong? Well with the Wonder Weeks it sometimes tells you, no you aren’t doing wrong your baby is making a “leap” that affects their mood, sleep, behavior, etc... and how to help them and yourself have an easier go of it. What I love also is it tells you when the “leap” should be over which really gets me through the tough times. I recommend this app to every mother or father who wants to know more about what’s going on in that sweet little head and also wants great expert advice on how to help your little ones along.

Couldn’t live without it. Wouldn’t want to.. Can’t even tell you how helpful this app has been in several ways! I recommend it to every new parent I meet. Here’s just a few things we love: 1st- when our son would be fussier than normal or not eating the same we’d check the app and wouldn’t you know he’d be starting a leap 2nd- it’s been amazing to know how our sons brain is developing, so much is happening in such a short time; we take so many things our brains can do for granted, their brain is just getting started 3rd- it helps us figure out how to interact with him based on brain development; we now can do activities that are right for him at that moment in time

Great for nervous parents. Thank God for this app! I haven’t noticed much until the last couple days (she has about 9 days left of this leap). She has been so fussy and napping much more. She’s also not been totally finishing her bottles. I keep getting nervous that she may be sick but she has no temp, no snot, nothing weird. Just a change in mood and some behaviors. She sleeps through the night but for 2 nights she woke up around 3 for her pacifier but went right back to sleep. Then 2 nights after that slept later than normal. I am so thankful for this app because I can look at it and understand that all of this is most likely just the leap. I am a nervous person to begin with so it’s so helpful to have some reassurance that she is just growing and this is normal.

This is a missing piece for new parents. This knowledge of 10 different stages of brain changes was a critical missing piece for understanding our baby. You can learn about baby’s habits, normal sleep patterns, feeding patterns, preferences, etc., but the part you would never know without this research is that their brains just follow this predictable brain change schedule. This is the missing piece to understanding why a baby is cranky or not. It helps you to not go crazy or frustrated or feel like you’re failing as a parent. So this is one of the few things I would recommend parents get, because they can learn a lot of the rest of things about their baby on their own.

Not real science!!. I recommend reading the Wiki about the Wonder Weeks before purchasing. I had not, used the app with our son for a few months. I was surprised by how little correlation there seemed to be between what the app said we should be experiencing with him and what was happening in real life. Once seeing the Wiki page, this made sense since it turns out the ‘science’ behind this is bogus. The researcher’s findings were not able to be replicated by future researchers and, to make matters even better, the researcher apparently attempted to stop other scientists from publishing their actually legit findings, because they contradicted his. And it sounds like he was a womanizer so three strikes. Unfortunately, anyone who finds correlation between the app or book and their baby is working off of a placebo effect. You read it and then you see it because the app says it’s happening. It’s unfortunate because it may define how some parents approach their babies needs, all of which is based off of nothing.

Gives understanding and insight to parents of little ones.. I’ve used this app for each of my 4 children. For my first it was definitely right on. I would wonder what is going on only to look at the app and notice we were in a leap. It helped me understand what baby was going through and how to be helpful. For my last 2 it’s been close not right on the dot but it still has given me foresight as to it’s coming, it says it’s coming but we’re already there etc. And gives me things to do with the babe to capitalize on the development they just had. I find myself returning to this app with every new babe.

Love this app!. The app has been pretty much spot on so far at showing what will happen when, and explaining why. My baby has been right on track so far with the developmental leaps and the fussiness phases were pretty much right when the app said they would be, and we can now expect them to be pretty accurate. I enjoy the explanations of what is going on with our baby, what she is learning and thinking and how it is affecting her behaviors. It is a great app. We have enjoyed the activities that it suggests to do in helping her to achieve her leaps. She has enjoyed them and so far has accomplished her advancements on schedule with what the app is saying. This is wonderful for parents everywhere, and can explain why the baby is fussier than notmal and let you know that you are not doing anything wrong, the baby is just experiencing a new challenge and to support the baby through the fussy phases!

My #1 suggested apps for caregivers of babies!. This app is SO WONDERFUL! As a mom of littles it can feel like a full time job guessing their needs before they can talk. This app brings a whole new level of understanding. Not only do I NOT think my kids are teething/and or sleep regressing all the time anymore but I now have this beautiful window into what they are experiencing. I wonder less “what are they thinking?” and instead see very specific changes like “she sees the contrast in these blinds, or “she’s categorizing this pattern in my face!” The book it is based on is so wonderful I highly recommend it. BUT this app stands alone. You need not read the book to benefit. The transition periods called “leaps” are specifically applied to your child down to the day. Plus there is a space to record in detail how your child handles each “leap.” I’ve found that even observation skills as a parent are benefited! I have never gifted an app other than this one. It seems a strange thing to give an app but it’s such a help to parents, especially new ones, that I can’t recommend it enough! Not just for mother’s! Fathers, grandparents, caregivers, ANYONE actively involved in a babies life can benefit.

One Helpful Feature. I appreciate this app mostly because of the calendar view, which tells you when your child will be going through a leap. I find that helpful. However, with the recent update, it has turned into a muddled mess of information, most of which doesn’t make much sense. Yes, it’s supposed to go hand in hand with the book, but surely they could have designed it in a way so that it is at least understandable without the book. The check lists aren’t very helpful to me because they’re just restating the fact that your kid is going to be grumpy and clingy during a leap. That information is already found under the What Are Leaps tab. It’s difficult to really pinpoint the problem with the app, but as another reviewer said, I think it could be summed up as too much redundancy. Everything is stated multiple times but none of it is intuitive or user friendly. I like the idea of this app and I hope they will be able to simplify it a bit to make it useful. Otherwise I’ll probably just delete it.

Great helper to understand my baby’s development. There’s so much to pay attention to and learn as a parent of an infant. And sometimes it’s tough to figure out why things are “off” with my baby. Often times I will check the wonder weeks app to see where we are when my little one is unusually fussy or isn’t eating well and sure enough most often it’s when we are entering a new leap. I have some assurance that things are okay. This app helps as a guidepost for our baby’s ever evolving development. In addition to helping us understand how our baby’s brain is developing we also love that the app gives games to play and things to do to help our little one develop even more. The activities are always age/leap appropriate and simple to do. The app isn’t always the easiest to navigate, but overall I would definitely recommend it as one of many helpful assistants in navigating the ever progressing development of a young baby.

No wonder everyone loves this app!. This app has been more than just a resource for what skills my baby is developing but it gives me peace of mind knowing when he is having a more difficult time than usual that it is of no fault of my own. It’s safe to say most parents’ natural instinct is to make sure their baby is happy and healthy. This app lays out the when the tough transitions occur, for how long, the signals to look for that they are going through the leap, and the skills they are developing and may choose to show after. My husband makes fun of me but I love this app because it’s sooo informative and it helps me to give grace to my baby and me during fussy times that I otherwise may think he was sick or something was wrong. Thank you wonder weeks for putting together such concise and helpful tips & info all in one incredible app.

App is too complicated and redundant. Not worth paying for this. There are so many options and every time I log into the app it seems like I am asked to do a homework assignment! Not concise and they give basically every option under the sun — your child may do this or this or the other thing, basically just equivocating, and in the end you just end up telling the app what your baby is doing and not the other way around (what your baby should be doing). I understand different babies develop differently, but honestly nothing insightful from this app. My advice is just enjoy your child and you don’t need this app. **Updated to 1 star from 2 star for the poor response from developer which do not acknowledge the flaws in the app, rather trying to defend it. App may have allegedly helped thousands of parents. Just didn’t help me (and may not help you) hence my honest objective review based on my personal experience. That’s how reviews work, the stars average out based on everyone’s personal experience. See other low star independent reviews that express the same sentiment as I have. Honestly only after leaving my review did I see others like mine and was perhaps not surprised they describe the same frustrations with the app. The UX leaves much to be desired. My advice is just check in with your pediatrician about your child’s development as we did (and as you should) rather than waste time/money on this app.

ZERO!!!! Didn’t find it useful at all. IF I COULD GIVE A ZERO RATING I WOULD........I didn’t find this app useful at all for a first time parent. I’m disappointed I spent money on this app. The symptoms/signs to look for at each developmental “leap” are exactly the same and i feel they describe a baby, that is tired, hungry or overstimulated. I don’t feel it describes anything close to what to prepare yourself for or how to comfort your baby that is obviously unhappy. Each section that describes the “leap” your baby is transitioning to doesn’t tell you anything specific about what new skills or sensations your baby will/ should be developing. I do feel each section describing a leap provides you with very vague signs/symptoms of fussiness or being a baby in general. I’m sorry I purchased this. UPDATE....developer reply was LESS THAN HELPFUL. They didn’t offer to help or fix anything. Developer reply doesn’t even attempt clear up any information about “leaps”. CONTINUES TO BE COMPLETELY DISAPPOINTED IN THIS APP. Very sorry money was wasted on what the developer claims is book and scientific research worthy, it’s not worth any of my time. VAGUE SIGNS ANS SYMPTOMS ARE NOT HELPFUL OR INFORMATIVE AND CERTAINLY NOT WORTH ANY MONEY; google is more informative.

Best app to invest in to prepare for your newborn. If you are going to invest in any app for your newborn this is the app. I am surprised there is little information out there about leaps. I did so much research while pregnant and never heard about it until my baby’s doctor told me about it at her 2 month visit. This app has been so helpful because it really helps me understand more about what she is going through. I am way more patient because of this understanding. I wish I knew about it before she was born to mentally prepare better. I highly recommend the ebook as it goes into more detail about each leap and what we can do to help them grow and develop and be more compassionate during the hard times.

Good app, update threw me off. The leap schedule alone is def worth the $4, the sanity it gives is priceless. Knowing that the stormy period will come to an end and your baby will go back to the sweet angel they once were is such a relief! I found that to be the most helpful and useful part of the ap. Leap 4 was awful but it ended exactly on the day it said it would. We were both about to loose our minds. Im a first time parent and the ap updated just before leap 5, i like the new look and format but not the the interactive parts. Like other reviewers the diary part is not useful, I really don't have time for that. Much preferred the previous way clicking off each task when accomplished. Im often interrupted and like being able to pick up where left off. Developer, please can you double check the skills? Leap 6 says baby will ASK someone to sing a song & understand the names of animals.. baby is not close to being that verbal.. im wondering if something glitched. Also I tried to use the nap tracker and its more trouble than its worth. Have to be able to pick up where i left off, not enter start and end at once.. or all naps. I tried to do it as the day went and it didnt add the total time together. i can barely remember how many time i fed baby last night. Please make things as simple as possible, my brain capacity is limited to most crucial items or not at all.

Excellent tool for parents and family members. I am so thankful for this app and the book as well. It’s almost always spot on with timing of leaps and the reminders for parents who feel like they’re going crazy are truly helpful. The info about your baby’s development is great to learn and not something one would know just by spending time with their baby. Now I have a greater understanding of what my infant is going through each week. The app itself is a great, succinct version of the book but I highly recommend having the book as well. It gives much more color to each area and more detail the app can’t provide.

Not worth the $$$. Just not worth paying for. The timeline of the leaps and predicted behavior were off. Also, it’s literally just an app that says, “baby may be more fussy” or “baby may sleep more poorly”. But doesn’t provide creative ways to soothe baby. It just makes you pay to confirm your baby is going through developmental stages you could find for free with a Google search. Annoyed I fell prey to this purchase as a FTM. After 1-2 months I completely forgot I even downloaded this app because it was useless. And as pointed out by the developer response, some Google searches can be misleading. However it doesn’t take much to find scientific research on baby development that is peer reviewed/ credible. Or literally ask your pediatrician to print a handout of the timeline developmental milestones- FOR FREE. Still don’t believe that what you actually get from this app is worth paying for.

Informative but can make you crazy... I understand the intent of this app and I love learning about what my baby is learning about! However… I also think the “leap days” can cause unneeded anxiety for parents. For example, my son is in leap six right now. It says this leap is estimated to last 28 days total. That means 28 days of potential fussiness from my baby. Do you know what that does to a parents brain?? Now obviously I know my kid isn’t going to be fussy for 28 straight days.. but for some people, this puts them on edge. Parenting is hard enough without being told you’re baby is going to be fussy for xx tie. Personally, I ignore the leap calendar and instead just use this app for the information it provides.

More parent input. I think this app would be better with more parent input. Meaning, if my child is experiencing x,y, & z then they would be going through a leap. But this app TELLS you when your child is going through a leap. For my child it has been so inaccurate with the dates. It’s almost the OPPOSITE of what he is experiencing. The one feature I do like about this app is that if my child is fussy for a few days I can look at it and say oh he might like A or B (things the app suggests due to a growth). And it typically helps the situation. However, because it is not lined up with my child’s actual leap schedule. I have to search all around for ideas through different leaps because he’s not coinciding with what the app has him scheduled for. I downloaded it around 2 months for him snd it keeps saying he didn’t ever go through the previous leaps. Which is also so annoying. If it had asked me what he went through and when it could have gotten a better idea of what his schedule is actually like. This is just a generic schedule based on my baby’s conception and birth date. I am disappointed I bought it.

Not accurate for us. I have heard many people say this app/the book are amazing and an incredible predictor of their baby’s mood and skills, but we saw basically 0 correlation between the predicted “leaps” and our baby’s mood, sleep, or skills. Sometimes we would get to a leap and he was already doing some of the skills, sometimes the skills seem impossible and way outside of the appropriate milestones (eg at 9 months: “asks you to sing a song”... how can a baby who cannot speak articulate something so abstract? Am I crazy? How could they be possible?). Aside from making me feel like my baby was failing to live up to some of these ridiculous “skills”, I saw no correlation between his behavior and the predicted leaps. Currently, we are having a really hard few days- lots of crying, super clingy, poor sleep— well the app claims he is in a “sunshine” part of his development, so he’s supposed to be happy and doing well right now. I just don’t get it at all. For us, it seems complete garbage.

Highly Recommend. We’re loving this app. We’ve used it since the very beginning. Even if you don’t get to use every feature, the info alone is spot on. My daughter is routinely in the 2 week margin ahead of schedule but we think now, this last leap or two (currently ending leap 6) she’s more in line with the typical timeline. We’ve recommended it to so many parents. I’ve heard someone say leaps aren’t evidence based but it’s working for us. I think the concern is it replaces profesional advice. Of course if you have concerns always communicate with your pediatrician but it still helps give us a little glimpse into understanding what could be behind her different moods. And even if you don’t agree with all of THAT info, the tips and suggest on how to utilize each leap and work with their development is super helpful! I feel like I don’t do enough to stimulate her or support her development and this really feels like I’m taking advantage of all her new skills and abilities. This is just as important to my husband and me as the week by week “your baby today” updates and descriptions.

Generic and wildly inaccurate info.. It’s not an expensive app so I guess if it makes you feel better when your baby is fussy and you want a ‘reason’ then go for it. But if you TRULY want to understand your baby and teach them based on where they are at developmentally this ISNT the resource for that. I haven’t found it to really be worth the money. Seems like according to the app your child is almost always in a leap with maybe a week or two break in between. The milestones and what your baby might be able to do are definitely not accurate amd often not even developmentally age appropriate. For my 5 month old, his current leap says he may CRAWL after a parent. Uh, what? I thought this was based on research, what 5 month olds are crawling? The ‘activities’ to do with your baby to help during the leap are super basic things that you are probably going to do anyway.

Not user friendly. App should be more user friendly. I see clouds and storm symbols but you can’t click on them nor does it explain it on the app what they mean.. I eventually figured it out but it’s just not direct and very disorganized. My sister loved this with my niece and I remember it being spot on back in 2015. My experience... So/so.. My son is accomplishing these leaps 2-4 weeks ahead of schedule and to a complete T. I asked my friend who uses this and she said the same thing with her daughter. The good thing is it helped me understand why suddenly my son was fussy, more clingy, or usual things aren’t cutting it. So I was more patient understanding he’s going through something and able to prepare. But I wish it would adjust with your personal schedule and use a “smart adjustment” technique to predict your child’s personal track. Therefore less offense with other parents I’m seeing in reviews..

Highly recommend. I am a grand parent and been having my granddaughter once a week since she was 6 months old I have found wonder Leap very helpful learning along with her new found skills and what stages she at incorporate this with games and her awareness as she developed. She is now 26 months and a wonderful little being thank you Wonder Weeks I highly recommend your app to all new parents for great guidelines raising your precious little ones.

Good, but not worth paying for twice.... This is a very good app, it has been very helpful and accurate with our baby and i was definitely glad i bought it. However, the new updates want a subscription service to access parts of the app, and its just not worth that on top of the original purchase. If you want people to pay for an app twice, and continuously, you need to make it worth it.

Limited content on this paid app. Although this is a paid app, it only lists examples of behaviour to look out for and refers the user to buy the book for the full list. So despite having paid for the app, I need to make further purchases to actually get a good understanding of my baby’s behaviour during a “leap”. If I’d known this before purchasing the app, I would not have bothered buying the app. The developer has responded to my above criticism that this app was advertised as a “summary”. I’ve reread the description of the app and do not believe that this was clearly advertised. The key features even say, “learn ALL about the leaps and bounds and the fussy phases of your baby” and “Read the bestselling Wonder Weeks book here in this app”. The description does not advertise the app as being merely a summary if further payments are not made.

Not great for anxious parents. I enjoy the information, and its ease of access through the app. But I found that the app gave me a bit of anxiety about my baby’s progress. I used the app for my second baby and even though I knew he was developing well, the app did make me feel at times that he wasn’t measuring up. I use the app less now, and only use it for reference. If you’re anxious, the book may be the better option for you. It is much clearer and somehow feels less like a bunch of goals that are to be ticked off the list.

Default masculinity, mandatory binary gender. Like many other parents now, my partner and I made a careful and considered decision to use they/them pronouns for our baby because we don’t want our language to shape the our assumptions about our baby’s gender identity. For us, for trans people and queer parents it’s upsetting and alienating to choose ‘unknown’ for the gender (this is accurate because we won’t know anything about their gender until they tell us) and for the app to then apply he/him pronouns to our baby. It’s incorrect and unnecessary and makes it hard to use the app. Hopefully we can still get something useful out of it but this is really frustrating right off the bat and makes us not want to use it. They/them pronouns would be ideal, but alternating he and her would be better than it currently is. Thanks

You Need This App. For all those mums who don’t understand why their baby’s behaviour has suddenly changed, who blame themselves for a clingy, crying bubba or who want to know some of the developmental milestones their bub will be moving towards - this is the app for you! As a first time mum, this was one of the most amazingly helpful apps for understand WHY my babe changed his behaviour and it ALWAYS aligned perfectly with a leap; usually to the DAY. Well done Wonder Weeks, you have made mums everywhere breathe a sigh of relief, a sigh of understanding; knowing that “this too shall pass” when the next leap is over!

Love the update!. Hello! A friend referred me years ago to The Wonder Weeks app and I have used it for both of my sons (a now 4 year old and 13 month old) and I have loved it both times. I was actually sad when my first born had no more leaps on the app! Ha. But I think this most recent update has been the best one yet. It’s beautiful! And extremely user friendly with the summary, abilities etc easily accessible through the “more” tab. Excellent. Well done. The Wonder Weeks has helped us understand many tough times with our boys and it’s a great resource for all parents. Thank you!!

Love the New update. Really enjoying the update to the app!! So much more insight in understanding the leaps and development!! A friend of mine recommended getting the app to help understand when my twins would transition and understand the signs of their developmental leaps. The update to the app has proved to be a game changer, with the more user friendly layout, the detailed information and the little videos to help give us adults a visual and more in-depth understanding of what our bubs are going through, it really helps take the guess work out of what bubs behaviour means.

BEST INVESTMENT EVER. This app has been absolutely priceless. I am a second time Mum with an 8 year gap and I seriously wish I had this app the first time around. It takes away the guess work, has helped me to be interactive with my baby based on the abilities I learn about in the app and has been a sanity saver when she’s been extra clingy, grumpy and waking frequently... because I can see she is in a leap and even be prepared for them! HIGHLY RECOMMEND! I also have the book and journal and have loved them all.

Love this app!. Honestly has helped me better understand my baby and the challenges we have faced. We just went through leap 7! Wow what a leap! For my son it changed his sleep- would wake up after each sleep cycle. So much awareness came with this leap and also started walking! By far I feel the hardest leap for us as parents. Good thing though he has now started longer sleep stretches after finishing the leap. Have loved the leading tips too as have really noticed him growing in these areas.

Customer service awful and left feeling ripped off. I had paid for this app and after a 30 second click through, I realised very quickly that it wasn’t what I expected and very US orientated. It didn’t suit my needs to I immediately got in touch to seek help and kindly requested a refund. I eventually got a reply saying that it wasn’t to do with them and basically tough luck, it is what it is. I’ve tried to get in touch multiple times to resolve. It’s been very unfortunate and left me feeling ripped off as a customer from a money grabbing app. Still no response after several requests for support and a refund.

Over priced calendar. Not really worth the money spent on it. The best feature is the set times for each leap, you could easily work this out yourself and add to your calendar. It is the other features I would expect to be great such as the videos of each leap, however, they are mediocre at best. Interactive videos about each leap along with how parents could get the best out of each leap would be what I would expect for this price. The app itself is a clunky over glorified calendar.

Leap 2 on point!. Journey, my baby girl- has been pretty good… not too fussy. Just a little bit more clingy at night… but have just rolled with it and giving her more comfort and face to face time and cuddles… I feel like she has gained more nice ways to communicate her needs- and I have been very sensitive to it, working it out. It been a very cool leap in her skills and watching her growth blows my mind.

Peace of mind. My baby is pretty good.. doesn’t cry much, loves her sleep, and has self settled from 8 weeks. So for us, noticing the changes in her behaviour/mood is quite easy. When I notice these changes... I check the app and it has been 100% accurate for her. I love the peace of mind it offers with its reassuring information, advice, and tips. Highly recommend this app.. especially for new mums.

Useful to know what to expect; don’t take too literally. Sometimes our babies behave strangely and once a physical cause has been ruled out, it can be oddly reassuring to know that it could be that a whole lot of overwhelming activity is going on in their little brains. This is what I find great about the Wonder Weeks app and book - and offers an explanation and often it’s description i’d behaviours is accurate. Babies can be fussy during the leaps but once they’re over, or even before, they know how to do new things that amaze us. Just remember all babies are different so don’t take the information in the app too literally. Also, not sure if it’s things getting lost in translation but some of the descriptions and examples in the app are downright bizarre. Ie ‘your baby may be fascinated by a vomiting dog’.

So helpful. This app helps me to easily see and navigate where my child will be at developmentally. I love reading about all the skills they will be acquiring bit by bit. Also helps me to understand my baby more and why they’re mood may be changing when they’re going through a leap.

Inaccurate and a total waste of money. This app has been inaccurate for my daughter all the way along. Yes the due date was incorrect for starters due to doctors disagreement of age during pregnancy but once she was born and due date was corrected this app still didn’t track her development right. I even changed her due date on the app to have the first few leaps line up correctly according to their predictions, from leap 3 onwards was totally inaccurate. She was experiencing leaps at completely different times, then when you go to add in signals and skills learnt they are all the same?? So many missing skills she’s developing that aren’t even there and repetition of skills that have been option for months. Completely stopped using it for the purpose of “Wonder Weeks” and just started using it for notes, photos and tracking naps. Then today went on the app to insert her update for the day, save it all and all my data and notes of her progress gone! Tried restoring my app to its last back up and that didn’t even work. Total waste of money!!!

Invaluable for time poor. I bought the book, but didn't have time to read much of it. Getting some sleep was of more importance. The app was a great short version and reference tool. We've had the app for over a year now and it has been like clockwork for our babies development. A great source of information to know what to expect, when, and then see the development happen. Awesome!

Google Things. Wonder Weeks is great for judging when our son is going through a fussy phase although he may do that sooner or later we know it’s around that time. I found is so useful with our daughter who was keeping up with all the “things” baby should do in this leap… but with our son it has actually made me second guess whether he is developing fast enough so I’ve had to google a lot - he is fine & hitting all his targets just not the targets on Wonder Weeks. So just make sure to google things before worrying yourself. Some babies develop differently & instead of knowing what sound a car makes & saying “vroom vroom” they might know what sound a dog makes “woof woof”.

Best baby app!. Wonder weeks is great. It predicts fussy and difficult patches for baby and we are able to understand why and help her learn and grow by supporting the new skills she is trying to develop. Our bub always starts leaps a day or two earlier than predicted and we can follow along and use the suggested games to help encourage her development.

Very useful. Definitely accurate with the timing. It is also helpful when you think bubs is unsettled and you check on the app and see that bubs is going through a fussy stage. It is also great as it gives you a heads up when they’re next leap will be so you don’t feel your in much of a shock when it happens.

Piece of Mind for FTM. I love using this app as a guide to help me understand better with what my little one is understanding about his world. It is really fascinating and sort of gives me a piece of mind that he is being a little bit more fussy or clingy etc. I don’t use it as a bible as it is also important that all babies are different and it shouldn’t matter if they are not reaching every milestone. I like how it gives me examples on how to cater for leaps too!

Good but needs improving. Unfortunately my son didn’t read The Wonder Weeks so while some of it was helpful, most of it didn’t apply to him until months later. No development issues or growth issues but The Wonder Weeks appears to be structured for more advanced environments. It would be nice if the skills that weren’t ticked off in the last leap, be available in the next leap. It would make it much easier to track your child’s progress. I also feel that my son was more in tune with the leaps being calculated from his birth date and not his due date, unlike the book states.

5 Star App. Love it! Keeping up with baby’s growth is so rewarding. Going back and looking into your diary with the photos and notes i made it means the world to me even more now and so glad i did it. U forget and then u remember because u wrote down all the important moments. This app has been great and so explanatory with all the leaps my baby went through. easy to use. I loved all of it.

Old VS New. I absolutely LOVED this app and have been using this since August when my little one arrive. However there has been a recent update in which when I am using white noise (heavy rain) it is no longer a continuous and uninterrupted. There is a clear pause when it loops back which is incredibly annoying since it never did it before. I also used to have to ability to scroll through the Wonder Week app itself and still have the white noise playing, but now it stops. As I said loved the app and if these things were to be rectified and put back to the way they were I would LOVE it again and would give it 5 stars no problem.

Review. With the wonder weeks app I found that it helped me give my daughter what she needed and it also helped me out my mind at ease. For an example if she was super fussy I’ve tried everything, feed, dummy, cuddle, bath, shower, play time, massage etc. I’d check the app and she would be experiencing a leap. So I knew I wasn’t doing anything wrong. And it helped me navigate what she may need or want. Great app for new parents!

A shame. It’s a shame that this app positions things in absolutes. E.g. ‘your baby now grabs things with both hands and no longer misses’. The information is helpful, but if your baby develops even slightly more slowly it makes you feel they are behind. It should say ‘many babies’ or ‘most’. Or offer some reassuring content if you aren’t there yet. My baby is always about 2 weeks behind. You shouldn’t do this to new mothers. The mums in my mums group feel the same so I know this feedback is shared.

A game changer for parents. My eldest son is 22, and I had never heard of wonder weeks or leaps.. I remember the frustration of not knowing what was going on for him, nor could I cater with resources or the understanding of, and patience for a leap, the way I can now! FF all these years, I found out about this research, book and app when my now 5yo was born. It gave me so much insight and more empathy and patience to cope with the draining sleepless nights, constant whinging and fussiness with feeding, associated with leap behaviour. I can now recognise when my 7mo is starting a leap even before the app notifies me! Watching his amazing milestones unfold after a few awful nights sleep, makes it all worth while.

Start dates not adjustable. The app is useful in anticipating, preparing for, surviving and thriving through developmental leaps. However as specified by the authors themselves, wonder weeks can start up to 2 weeks before or after the “expected” date in the calendar when based on due date. For those instances where a leap has started before or after the predicted “expected” or average date there is no way to manually “start” the leap so that the countdown and advice adjusts accordingly. Eg. My baby has started their leap 6 days early. The app only says “6 days until their next leap” but I would be better served to start it so I have the leap advice and “9 days until the leap ends” countdown. Similar to a menstrual cycle tracking app, the prediction date should be included to allow parents to anticipate upcoming leaps, but the app should allow for parents to manually specify when a leap actually starts for them to get the most out of the app.

Grandma Jolly. I cannot speak highly enough about this app. I had the very special privilege of being under the same roof when both of my daughters brought home their babies which were due 2 days apart but born 20 days apart. Leaps and discoveries where mirrored by the app. We all lived together husbands, wives and babies for a beautiful 12 months and this app was brilliant for being peace of mind into the equation of caring for a newborn. When it was clearly explained what part of the brain was developing to connect with how the baby was reacting to the world around it, it was so assuring for a new mum. I so wish they had had this when I had all my babies.

Wonderful!. This app is so useful, accurate and full of connecting resources to guide us through our new baby adventure. There is so much to read instead of small snippets backed by real science plus you can download in app or separately to read the full books. Suggestions would be that you can click on the storm cloud from the chart and it goes to the relevant information & that the ‘all leaps’ section has a date/weeks reference next to it so you know the next bit coming up.

Waste of money. Purchased in a desperate sleep-deprived stupor. Doesn’t really offer any information that changes or informs how I interact with my baby. Very little content or interactivity. Just a bunch of one sentence descriptions of games you could play with your baby, which you’re probably already doing or have already read about on a million baby sites and forums. It gives you the option to check off these games but play with a baby doesn’t tend to be this formulaic and organised. I’m fascinated by the developing brain of a child but it’s much more valuable to read a book like ‘Brain Rules for Baby’ by John Medina or ‘The Happy Sleeper’. Just one opinion. :)

Lots to explore with bubs. Gorgeous app, lots of gems here to give little one the best start in life. The app is not 100% intuitive to navigate, and for those who come to the app late it would be great if could tick off prior leaps without causing bugs. Worth the price especially to give mum and dad confidence on why the grumpy weeks are happening, and very enjoyable.

Not particularly useful. I find the app weird and glitchy - some videos are just a blank screen when I press play I.e 2 of the 3 videos in leap 3 “smooth transitions” wouldn’t play. Some of the videos and explanations don’t seem to be helpful or easy to understand analogies ie. leap 4 “Events” uses the analogy that adults understand that when a ball is dropped it may bounce again and again. Huh? Are you referring to cause and effect? Child development involves some really complex concepts and I don’t think the app explains them particularly well. I certainly don’t think the app is worth the cost.

Great for first time mums. I know this app gets a backlash for predicting to the day when a baby will go through a leap, but if you read the book it explains that it does not predict things to the day but lets you know of some things that have been observed to happen at the earliest time it could potentially happen. For me it has been good at predicting when my baby might go through some sleep disturbances, experienced separation anxiety and when she has started interacting with her surroundings. To me this made some of the tougher times easier as they did not come as a shock and I could better understand why it was happening.

Several errors. In the beginning I loved this app, however as we got through to more leaps the app has SO many errors that defeat the purpose of using the app. The skills described in many of the leaps are very inaccurate, not age appropriate and it ends up telling you nothing about what your child has learnt during that period. Extremely annoying since this app is not free, I’ve paid to learn about my child’s development and better understand what they’re going through and I’m not getting it. The timing of the leaps for my child has been accurate.

Hesitant at first but now a believer.. At first I thought it wasn’t accurate as my newborn is premature (35 Weeks) and I was imagining that he surely had gone through a leap already, but yep surely enough during the predicted leap 1 dates he was irritable yet seemed taken aback with all the new senses and found that this makes more sense now to use the due date instead of the birth date. We will be prepared now for next leaps.

The bestttt. I used it 6 years ago when my first child was born & knew I had to have it again Absolutely spot on, whenever I feel like I mustn’t be doing something right I check out the app if his having a fussy day it’s spot on, & it gives amazing tips and explanations as to why baby is the way baby is at certain times 🙏

Reasonable app. Helpful info and a nice way of recording development as your baby grows. Latest update keeps freezing and not saving when I try to add a picture which is frustrating. Also lost the notes I’d made in the prior version! :( Needs rewording on what you actually get in the app as you can’t read the book as it suggests without paying extra. I would also suggest a chance to trial the extended options- eg the baby monitor- before committing to the spend. I’m interested in trying it, but want to know if it will work for our set up before committing to a 3 month payment!

Excellent app. Extremely accurate with my last baby. She started every ‘fussy stage’ exactly 3 days early each time and the new things she was doing and learning was spot on. It explains so many things that remained as unanswered questions and self filled doubt with my older children. You just start to think you have figured things out and they change everything again and you can’t work out what’s happening or why. This app explains it all!

Excellent - a must have for new parents. Wonder Weeks is amazing, it lets toy know quite accurately about your child’s development, what you can expect and when in terms of skills. It also gives you tips on how you can support your child. I highly recommend the paid version as well for extra detail and tracking

Useful tool; very anxiety reducing. As first time parents, my husband and I have found it extremely useful. I’d highly recommend others use it, but just keep in mind that they don’t have to hit every milestone at each leap to still be on track. It’s a nice tool to gauge where they’re at developmentally, and to see how you can better understand what they’re going through to help them through it.

It’s amazingly helpful.. It’s been very helpful in understanding my child. Especially when she is being fussy for no reason and u have checked off everything on the usual list. Obviously it’s can’t fix the fussiness but it’s easier to deal with knowing there is a reason behind it and I feel more sympathetic towards my child instead of getting overly annoyed. It’s a wonderful app and I highly recommend it to other parents.

Confusing and dates don’t match. This app is not user friendly at all. It’s very confusing to navigate. The dates have never matched. For example, it’ll say a certain leap starts around 12 weeks after due date but then on another page of the app will tell me this very same leap is due to start about 13.5 weeks after due date. So completely conflicting information. Has been the same problem for every single leap. I emailed them about it and all they said was to try putting in a different due date. But why should I have to put in a random (wrong) due date! Completely ridiculous app and a total waste of money. Can’t use it as it makes no sense.

The Wonder Weeks. This app is honestly a godsend! My little one was into the second leap before I got the app and everything just makes sense the. and gives you some guidance around their development. I now have 2 bubbas and the leaps can be like clockwork with obvious signs and other times they don’t show a lot of obvious signs. But it’s so reassuring when your baby becomes fussy and sleeping changes and you don’t know what’s wrong, they’re not sick etc.- check your app and oh he’s in a leap! Then you can read up on how to support them during that time and understand what they are learning. The reassurance and knowledge is amazing. Highly recommend!!!

Great content, crappy app. The content itself is very helpful and generally spot on (a week or so off on either side of the leaps which is normal since each baby is different). The app itself, however, it needs some work. The sleeping schedule has ongoing issues which have been raised with their impeccable customer service. A new version was coming out that was meant to fix the initial glitch, and it did fix it but only for a few weeks. It now has issues again where it does not record anything you put in unless you put it in 3+ times. I do not use the other features and so I am unsure if this is an issue throughout the app, although it can be a little frustrating not being able to use the main features that come with the app. Hopefully the developers can kindly get it together and resolve this ongoing issue, as some parents do rely on these paid features.

New update is a scam. I wrote a 1 star review just over a week ago after the new update (it seems to have disappointed or has been removed). I’ve checked back and while you have responded to the negative reviews by unlocking the rest of the ‘checklist’ feature. It’s still not good enough. People have already purchased the full app prior to the update that had heaps of videos and content included. Now these videos have been removed and I believe a lot of the other content too. I don’t think it has been an improvement at all - rather a way to scam more money out of those who have already paid. I won’t be recommending this app to my friends or family anymore.

Would buy again. It’s been fantastic and on point with my first little one. It has made me be a different type of mother, more understanding and comforting in times of her leaping. It is equally as hard knowing that there is a whole month ahead of leap, as there is to know when it will end, but the wonder weeks app has helped me endlessly. Thank-you wonder weeks!

Terrible update!. The language used in this app was already dense, and now it’s even worse. It flips between first person and second person perspective all within the same paragraph, so you are never quite sure whether they are talking about the baby or asking you to think about yourself!! The way they have displayed the text makes it harder to read, and the redesign of the chart is awful - it was so much easier to understand when everything was bigger.

Very poor design. So confusing, can’t see what the last leap was or when it ended, how long it went for. Waste of money, I just deleted it within a day. Not much info and not user friendly THanks for your response. The chart doesn’t say where the leaps are or what leap it is. You need to go back and forth between the different screens and work it all out your self. It would be so easy if it just said ‘leap 2’ above the leap on the chart, and then even better if you could click on that and go to info about the leap, instead you need to work out where the leaps are your self, then go back to a different screen to read about. Waste of money

Great app. Full of information about baby development, and really useful for the curious and interested parent

Waste of money. I’ve heard people rave about this app, so I bought it and am totally disappointed. Spelling and grammatical errors everywhere, totally not user friendly, and on top of paying for the app they want you to subscribe to have access to the rest of the features? Colossal waste of money. Deleting the app and wish I could get my money back.

Not recommended. not helpful, no information is provided for preparing for the leap

Every parent should get this app!. Such a helpful app that helps me anticipate when my baby will be fussy/developing new, exciting skills. Love the different activities and suggestions I can do with my baby.

Just a bit silly.. My friend recommended this app, but I have to say it was fairly useless. My baby never showed any of the signs around the automatically generated ‘leap’ dates. And some of them were just laughable - ‘understands what an airplane is’ (8 months). ‘Washes dishes’ (12 months). Sometimes I just open it for a giggle. The information your local health authority publishes is probably more useful (and free). Edit: I didn’t say anything about ‘random googling’, I referenced evidence based material that is published by health authorities. The stock developer response is telling. What is misleading is telling new parents that they need to pay for an app to provide good parenting.

Helpful and eye opening. This app was so helpful and always spot on. In times I had no clue what’s happening with my little girl I would check the app and be like there you go next leap is on. All the advise, activities, education on infant development and tips given has helped us so much to understand what our little one is going through, which allowed us to handle every new stage with compassion and grace. I’ve recommended the app to many of my new Mum friends because of how helpful it was for us to

Very helpful. I really like this app. It is something that I don’t have to check everyday, but can reference when needed. I find the heads up on leaps very helpful in preparing me and my spouse mentally for a potential rough patch. As well, the explanation of what happens during each leap helps us to understand our child better, and connect with him at the appropriate level for that stage. Very helpful and I recommend the app to all new parent friends!

Educational, with more to offer. Love this app, I think it has led to more informed and beneficial playtimes with my baby. I do think that it could offer more to the user for the price paid.

So accurate. The wonder weeks has been spot on with both of my kids. If they seem off and I wonder why, I turn to the app and the answer is usually a leap!

Very informative!. Love this app for giving me insight into our newborn! Very grateful ❤️

Highly Recommend!. I was skeptical about this app as I didn’t understand how an app would be able to tell me when my son should be feeling certain ways. Now that I have been using it for a couple of months I am really enjoying it! I never take the leaps too seriously in terms of exact days that my son will feel a certain way, but more as a general idea. It helps a ton knowing what to expect from him within a “leap” and so far it has been fairly accurate! It helps me keep track of what milestones I can expect him to reach and gives awesome ideas for things I can do with him to expand his learning. I’d definitely recommend this app to anyone who is looking for insight into their littles’ development!

Timing off but info accurate. I think it’s a bit off with the timing for my little one. Things seem to happen almost opposite what the app says

Not worth it!. This app was strongly recommended by other moms and honestly, I don't understand why. It's a waste of time and money. Not once has my baby's pattern actually matched the information on the app (cloudy and sunny weeks). Not user friendly either. I got it hoping it would help me understand his moods but sadly, there's no such thing. No two babies are exactly alike.

Good app. It’s very helpful to know what may possibly occur in the coming weeks. While your child may experience some or all of the listed actions and it’s even possible for your child to experience the leap before the week is mentioned as leap. It’s worth it to get this!

Free apps are just as good. The app will tell you what change baby is experiencing/learning, the moods you can expect, and suggestions for things you can do with baby through play. Any free app has most of the same things, other than play suggestions and I just don’t think it’s worth it to have another app taking up space on your phone.

Super helpful. Always eases my mind when the baby is extra fussy and there’s Ana actual reason behind it

Frustrating. Bizarre UI, no shared parent access (money grab forcing 2 parents to buy it), and janky app. Super frustrating cause the premise seemed interesting.

Timing js off. We found the timing off. Our baby appeared to go through the first leap a week earlier.

Must for new parents. This app has given me the opportunity to better understand and help my baby as he is going through every leap of development!

Taking things day by day!. This helps me when my little one is acting up, I can see the big changes that are going on in his brain! And reminds me that things happen in phases and to take things day by day !

Helpful but some negatives. My baby displayed their “fussy” phase about a week prior to the expected dates in this app. Unfortunately there was no way to edit the leap timeline within the app.

Easy and interesting to use. Fun to watch your little one go through the development stages of the app.

The only app worth using. This is the only book and app worth reading to guide your parenting experience. Nothing else comes close to preparing you for the behavioural shifts that happen. It has been spot on every time and helps us understand what is going on with our little one.

Not useful. You can find everything this app provides for free on google. Don’t waste your money.

Life saver!!. We absolutely loved having this app at our fingertips for both of our kiddos. Whenever they seemed “off”, we would check and sure enough, they’d be approaching or already right in a “leap”. It was so reassuring as new parents. Lots of great info but easy to navigate.

Not accurate. Sadly this app has not been accurate in the slightest for my baby.

Ajuda mas poderia melhorar. Eu esperava um pouco mais de informações e dicas sobre os saltos. Meio engessado, e gostaria que fosse inteligente pra alterar ou que me sugerisse mudar a data, o salto do meu bebê sempre começa antes e acaba antes do previsto pelo app.

Waste of time & money. This app blows - don’t bother buying it! The « leaps » don’t really make any sense, and the app keeps contradicting itself about when the leap actually is. My baby at 15 weeks is starting leap 4, but the app also tells me there’s 25 days left in the leap, elsewhere says she’ll start the leap in 46 days, but also says that leap 4 starts at week 19.... what?!? Not user friendly. No explanations about how to use. For example, the calendar has little clouds over some weeks - I would love to know what that’s supposed to mean, but it isn’t explained anywhere. I literally can’t use this app (and I have a Masters degree 🤣). Completely useless!

Did not correspond with child’s behavior. Wasn’t helpful

Useless. This app just wants you to spend more money and isn’t helpful at all. It’s not user friendly and is difficult to navigate. I’m completely disappointed. I want my money back!!

Awesome app. Enjoying it and following it! Definitely puts a lot into perspective of what my baby might be experiencing

Not accurate, waste of money. The leaps are not accurate and some of these things that my child is apparently supposed to be doing at these months is just plain ridiculous lol don't waste your money!

Don’t waste your money. None of the leaps have happened to my baby in the timeframe the app says. The information is spotty at best and they push you to buy chapters from the book. Borrow the book from the library, don’t get this app.

Loving it!. So far, this has been pretty accurate. Knowing it was coming (and that it was normal) has helped my anxiety immensely. My baby needs extra cuddles and is being extra fussy… but, this app reminds me that it will pass and that they do learn skills with the Leap.

Disappointed. I’m honestly disappointed in this app, I expected it to be more informative and she’d light on my growing son, but it’s proving to be a waste of VM my money. The jargon it uses is too technical and there is an emphasis on explaining the past “leaps”. When discussing current leaps there is a lack of explanation. Please work on making this App so that I feel I spent my money on something that will help me!

4th leap. Everly went through this leap with flying colors, she was happy and started sleeping though the night at approximately 12 weeks. Once we figured out what her eating schedule should be once she started to sleep 9/10 hrs. She was perfect!

Terrible!!!!!!. Absolutely terrible! Wish I never paid for this bogus app. Don’t fall for the hype on this.

So helpful!. As a FTM, this app has been so great for helping me understand what’s going on with my little one when there are bug changes happening. It gives me peace of mind that I am still on the right track and I feel it has been very accurate so far.

Wonder Weeks Best Baby App!!. This is probably one of the best baby apps I’ve used. It helped with both of my sons to gain perspective on how they are viewing and viewed the works through various stages of development. I thoroughly recommend this app to anyone wanting to see things from their baby’s point of view!

Waste of money. This app is wrong and doesn’t actually follow any patterns. It was completely backwards from what we experienced with our baby. Waste of money.

It’s a no. My babe did not follow any of it. You stress yourself out looking at it being concerned they are going to be fussy. Just close the app and enjoy your baby.

Good for anyone believes in horoscopes. This app wasn’t useful for me. It’s just vague enough in the descriptions of “leaps” so that anyone can interpret it as their baby, but there’s no real useful information . Example: some babies might sleep more with this leap, some might sleep less. Some babies might eat more, but some might eat less... are you kidding me? I guess it might ease people’s minds that what their baby is or isn’t doing is “normal,” but this app really offers nothing you can’t get for free elsewhere. As a first time parent, the best advice I think I can give to anyone from my (limited!) 5 months of experience, read as much as you want (like frantic 3 AM googling... I did enough of that), take it all with a grain of salt, try different methods and find what works for your baby, and what works for your family. But all of this said, if having this app helps you ease your anxiety, then it’s money well spent. Just don’t expect it to tell you much. I also thought the design of the app was fairly sub-par.

Love it!. It’s been great using this app as a checkpoint for my son’s development! I found the tracker to be very accurate and helped give me piece of mind during the fussy faze

Not as expected. Bought the app after reading great reviews. But did not workout for my baby.

Terrible and False. This app is ridiculous. It preys on new mothers who are wondering why their baby is particularly fussy, or good, or tired, or whatever. No baby will do the exact same thing at the exact same time. Regardless of due date and brain development. It is an absolute SCAM do not waste your money. This is the worst app I have ever purchased. Every doctor I have talked to about it just laughs. I cannot stress enough what a waste this is. It’s even terrible visually, like what a poor old 1990’s app would look like. I wish I could get my money back and throw it in the garbage, because that would be more useful than this app.

So helpful!. I find it super helpful because I know what to expect and what is normal behaviour for his age. It also brings peace of mind on the rough days that it’s just a phase and we’ll come out of it soon enough. I like that it gives suggestions on activities to help development and explains how your baby sees the world at that point.

If you're unaware of the due date, get ready to do some reading!. The app's information is quite helpful, although it can be time-consuming to determine the appropriate level for your child without knowing their due date (because of fostering, adoption, etc). The app solely relies on due dates for providing information. However, if you're willing to read through all the levels, it's definitely worth checking out. On another note, I did notice that the videos don't have sound when my phone's ringer is off, which is different from other apps I've used. Nonetheless, I'll continue using the app to assess its overall performance.

A must for any involved parent. Most informative and entertaining

Don't get the hype. Saw rave reviews for this app on TikTok and so I bought it. I don't get the hype. The articles are riddled with typos, which is ridiculous because they're barely 100 words long. The diary function is effectively useless because it keeps deleting your progress if you don't immediately save. Apple needs to look into the pricing here because you're fleecing people with that $7 price tag for the same info you get on the free apps like Pathways and WTE.

Useless. This information contained in this app is not at all applicable to my child and is ridiculous

A must-have for first time parents!. The Wonder Weeks app was a life saver when it came to understanding what my first born was experiencing after being born. Recommended by another mom on a Facebook group after I posted my frustration and disappointment at understanding my child. This has quiet literally saved me from ripping my hair out. What I loved is it puts into perspective what your child is experiencing and made me realize it wasn’t me doing something wrong. Lots of examples of what to look for when a leap is coming, and tips on how to help your baby through the new things they are learning. Thank you...what a life saver!!!

Please consider changing back. I loved this app with my first, now attempting to use it is difficult. I dont like having to make a diary entry to find things out, the calendar with dates is hard to read now (used to be much easier). You should still provide a list of what to look for. This app has always been one of my top recommendations for new moms and moms struggling and I’m not sure I’ll be able to recommend it currently. Update: please fix the app calendar so im actually able to tell when the leaps are supposed to start. Also we just got through the first leap and there is no countdown to the next leap like there was when I used this a couple years ago or like there was with the first.

Helped as a new mom and breastfeeding!!!. This app has helped me understand my babies cries and clingyness when it came to leaps and growth. As a new mom and breastfeeding, it's so easy to get overstimulated and become "touched out". But this app helped me hold my baby a little closer during those difficult moments. And it helped me to expect when to give extra patience so that my baby can understand the world around her. Also loved all the tips and skills checklist; and that it's free!!! If it offered as much as the book I think it'd be 5 stars but for being an app it is way more convenient, so still great!

Used to be great. This app was incredible when I first downloaded it. However, recent updates have clearly stripped out useful information in hopes that you will spend more to upgrade the app to access what is now clearly missing. We are on leap 9 and the basic info is so badly edited it makes absolutely no sense, refers to things that have been deleted and mostly addresses the previous leap without providing the basic background to the current one. The developers should learn that the only way to get people to spend more money on a product is to make it better, not worse. This is incredibly frustrating as until now I had found this a very useful parenting aid to better understand my little one’s development. What a shame.

A must-have for new parents!. The wonder weeks app saved our sanity with our first child. Instead of wondering if something was seriously wrong with him or our parenting, (after getting the app) we understood “leap behavior”, and our stress melted away knowing our child’s brain and body was doing exactly what it was meant to do: grow! 4 kids later, it’s been so helpful for each one. We ALWAYS tell other parents who ask for any tips about the wonder weeks!

Seriously the best!. Some of these reviews say it wasn’t accurate to their baby’s weeks. The app does say to enter your baby’s due date which I did but it seemed a little off. So I just changed it to when my baby was born and it’s spot on!! She was born 3 weeks early if that helps. Every baby is different though. I love this because of the information is gives for each leap. It helps to understand why your baby is extra fussy and what to focus on to help them through each leap.

Useless. All babies are different, and I should have known better than to buy an app that supposedly applies to all babies. The leaps might be skills that all babies learn, but there is no way of knowing WHEN your specific baby will develop those abilities, let alone when your baby will be fussy or go through a “stormy” period. It’s pretty absurd that the book and the app claim to give these predictive abilities to parents with a calendar. The “leaps” didn’t coincide at all with my baby. I followed the rules and went by my child’s due date, instead of birthdate, but still the calendar/chart was SO off base. My baby would have fussy growth spurts, and sleep regressions, during projected “happy” periods. And my child would master skills months sooner or later than was stated. This app is useless. I shouldn’t have wasted my money.

Update is disappointing. I purchased this app shortly after my son was born almost 8 months ago. I loved the app and even followed a group on FB with other mothers with babies in the same leap as my son. I was extremely disappointed to find the most recent update to the app restricted previously available content and is now available for additional fees and subscriptions. I read in another review that the app developers claim the update is merely an extension to the original app and no previous content was restricted. This was not true for the updated version of my app. Not sure if it is because I have iOS, but still extremely disappointing. I used to recommend this app to every mom I knew, but won’t be anymore. I’m sincerely bummed because it really was a great app!

Wonderful App. It’s been so amazing. There were times at first before I knew about leaps that I thought I was going crazy because baby would just cry. Leaps are for sure something people should talk about more! It would’ve been so great to know this before I had my baby to be better prepared to help them develop like they should be. This app gives you everything you need though, all the info is there along side any questions you might have. It’s the best!

Saved my life and sanity. This app wonder years recommend to all moms first or second child .... it helps you understand child gives you heads up for every phase/ leap so you won’t go insane when baby is fussy screaming and inconsolable at certain times. I found it around 4 months and wish I know about it from birth. ! The apps is better than any class for birth and baby classes could ever teach you !!! I wish someone would have given me this at my baby shower !! So so valuable. Don’t waste another minute and download it even if still pregnant it will save your sanity. !!!

Wonderful resource!. I’ve read the book and got the app. The research is so interesting and stunningly accurate! Whenever I know my son is going through something, I check the app and book to get a better idea of how to help him. It’s not stressful to see leaps coming. Instead, it’s exciting to see what he is learning and helpful to know how I can better help him through tough phases. It’s a wonderful reminder to show grace when I begin to get frustrated and an absolute game changer to have this information!

NOT user-friendly. This app is a mess. The information might be good... if you can even find it. It’s such a pain to navigate. I wish so badly they would redesign because when I do randomly stumble on relevant information, it’s interesting and I enjoy it. Especially tips for what baby might enjoy that week. But then I can’t even remember how to get there and it’s way too much work. They need to streamline and make things much more simple and clear. Right now there are several ways to access the (almost) exact same info spread across the app. PLEASE consolidate. I’m looking for another app in the meantime. When I exit out of this review I’m going to download the Sparks or whatever one I saw advertised when I searched Wonder Weeks to review.

The only way to understand newborns. This app is the BEST thing to ever happen to raising babies. Its really the only thing that helped understand newborns sleeping patterns, needs, and milestones. SPOT ON for both of my children, almost to the day. When they randomly stop sleeping through the night I open the app and BOOM they’re in a leap as predicted. Huge peace of mind to know everything else is okay and it will end. When the leap ends/ back to normal sleeping they magically can preform the skills listed in the app. It’s the only way to understand what your baby is going through in the first year!

Sanity saver!!. We used this app through out the last 17 months of our sons life from day 1 and it has been spot on! We love knowing what to expect and if we forgot to follow along, our son would remind us with his behavior. He definitely lived up to the ‘fussy periods’ and we’d look at the app and sure enough he’d just progressed into a new leap. So nice to know there is a reason for these swings in mood and to just know what development is occurring so you can help your little one flourish. I recommend this to all of my friends and family who are expecting, if you’re a new parent THIS IS AN ESSENTIAL.

Don’t bother!. Eh. I wish I wouldn’t have bought this app. I saw such a mix of reviews for this app and now that I’ve had it for several months, I definitely agree with the camp who says, save your $. Instead of worrying about when your baby is going to go through the next leap, try to enjoy them instead! They are constantly going in and out of developmental phases-some are fun and some are hard. This is my 4th baby after a large gap and I never used anything like this before and my older kids (teens) made it through just fine and so did I. I rarely look at this app and every time I do, I’m reminded about why I usually don’t!

You’re doing great momma!. This app helps me to give myself a little grace in this whole mom-ing thing! Sometimes, during a particularly rough time in my baby’s development I feel like I’m spinning my wheels trying to figure out what more I can do to make things easier. Then I check my wonder weeks app and see that we’re in the middle of a leap, and I just feel a sense of release. It’s nothing I’m doing wrong, it’s just a leap, and totally normal. As moms we are so hard on ourselves, and this app has helped me give myself a little break!

So sad. I am extremely disappointed not only at the way Wonder Weeks App is blatantly ripping off customers, but also the developer’s responses to PAYING customers that USED to love the app. I got and PAYED for the app a little after having my baby and used to love all the information and resources it brought (hence the reason I was happy to PURCHASE) I went and checked it this week to find out that the update is pretty much an ad to get you to pay a subscription, umm I don’t think so. And NO, stop telling people that if you had the app previous to the latest update, you have all the same information as before; that is absolutely false and you know it. It seems to me that if I payed for something PRIOR to any update I should be given the option to mantain what I originally was told I would get and not tell me that it is the same thing.

Must Have Parenting App!. This app was a life-saver during the first 1.5 year of my baby’s life! When she was fussy for apparently no reason, we had something to turn to. It’s so hard seeing your baby be cranky! But not knowing what’s going on or how you can help makes it so much worse! This app will let you know when your child will be going through mental leaps based on their age. Leaps in development can also mean fussier periods. It’s also super fun to look out for and notice the changes that the app says should be happening! This app was spot on for my kid and I’m so glad I had it!

Amazing. This app has been very helpful. I recommend the book too! I will read each chapter as the leap nears. Feeling educated about what to expect has helped me maintain my cool. These fussy phases can be challenging but knowing it will come and go helps you relate and empathize with your child, and yourself. It also helps you recognize their new skills. At the end you feel a sense of accomplishment and it truly is bewildering to watch your baby master their skills. Keep in mind it is a guide, not a concrete timeline. My child has gone through a leap early by a few days here or there. Happy reading!

The most accurate I have found!!. I have to say, I rarely will spend anything for an app and this one was referred to me by a child specialist. So I purchased it after I had my last daughter. It was so accurate with mood changes, etc. it was unbelievable!! I also bought the book but I have to admit I haven’t read it yet. Now we had a boy and it is truly amazing, we were just saying how our son is looking at us differently, today was his first real smile and then I open the app and sure enough, he’s in his first leap!! He was premature so I do go by his due date, and I couldn’t be more pleased!! Thank you!!

WORTH THE MONEY. This app is truly amazing. For first time parents, like myself, this app has offered so much information and made things so very easy. It has helped so much in understanding how your baby develops and all the changes they will go through. Most weeks it has been so accurate it blew my mind. Right down to the smallest detail. The leaps that the child will go through has also been very accurate. I encourage everyone with a newborn to download it and enjoy! IT IS WORTH EVERY PENNY!

Worth the money!. This app is great to gauge when my babe was going to be developing new skills and to help further improve that. My only dislike is the multiple statements at the beginning that say you are supposed to enter in the actual due date to gauge everything in the app. Even our OB seemed to agree that the date of conception was two weeks earlier than the typical “last cycle” where the typical due date is defined. So at first we were off about two weeks off in the app, until we shirked these statements at the beginning. Now the app really is great.

BUYER BEWARE. If I could give this app one star I would. Beware: I used this app to keep track of my newborn’s “firsts,” and unfortunately all of my data is now lost. My information got deleted as the app stopped opening. After I sent my first inquiry request for app support, they asked me if it was my update version or model of phone. I have the newest update and newest phone. I even sent a video screenshot of my experience. The only response I received was to reinstall the app which I was reluctant to bc it says I would lose my data. I sent countless emails and never heard a response back. It has almost been 2 weeks. I did reinstall the app, and sadly my information is now all gone. These journal entries of my newborn were priceless, and now I am heartbroken. DO NOT BUY THIS APP.

An App so nice I bought it twice!. Used it for both my children and it was invaluable both times. It helps make you feel more confident when baby is fussy and it seems like nothing will calm them (not you but a fussy phase!) or when Baby randomly stops sleeping and is suddenly clingy (leap!). I also LOVE the warning notifications when Baby enters a new Leap, and the suggestions for how to engage with Baby to help build their cognitive and physical skills. Recommend it to all my new and repeat mom friends alike.

Unhappy Customer. After paying for app, you don’t expect to be asked to pay for a subscription to see all of the content. Originally, this was a great app. I would have said 5 stars, but then they updated it and took away content. They say the subscription has “more” content, but I felt like I could see way more before they made it a subscription service. I’m very disappointed with the recent updates that they have made. It seems to me the app makers just want to make more money at the expense of the people who have already paid their share. On top of this, the app isn’t as user friendly as it once was. All in all, I was fooled once into giving my money to this app. I will not be stupid enough to do it again through a subscription service. No thank you!

Not helpful. I have three kids and I’m always hearing people talk about leaps. With this recent third baby I figured what the heck, I’ll give it a try. Total waste of $2.99. I wouldn’t be so annoyed if it were free, like frankly most apps are. It’s just extremely vague about what the leap entails... “baby may eat more... or less! May sleep more... or less! May be cranky... or smiley!”... okay, so basically baby will act like a baby in some way. Got it. It offers very little as far as developmental information or advice - there are literally just a few sentences for every leap which occur roughly once a month. In my experience, none of these leaps have lined up with my baby’s behavior changing. None of the information is really in any way unique, nor does it help with what everyone actually wants to know (ie, what do? Feed and sleep routines, etc) What to Expect or Babycenter are much better, and both are free. Both offer tons of information, FAQ, forums, helpful short articles, etc. I also highly recommend buying the Babywise book. This app? Save your three bucks.

This app is a must have!. I’ve used this app for 2/3 of my kids and let me tell you it really is so nice to have an explanation for these fussy periods babies go theough! Instead of feeling so frustrated struggling to calm my baby I feel more empathetic knowing baby is experiencing new things with each leap and it gives me a light at the end of the tunnel knowing it will pass in just a few more days. I’ll add tracking baby’s leaps has saved me from unnecessary sea appointments! I almost took my baby in last week but checked the app first and sure enough it was just a leap!

Ava leap 5. Leap 4 was a BEAST. We were dreading leap 5 around the holidays. BUT Ava wasn’t as fussy as we thought she would be transitioning into leap 5 at Christmas time. The best part of the leap and this timeframe, was her attention to family members and her happiness being with grandparents and us alike. She’s such a kind soul and knows she’s safe with a large core group of caregivers. They all have the app and are following her growth patterns and we’re aware of potential cranky crying and clingy moments. We made it through thanks to the education points learned from this app.

Helpful information. It is very helpful to know what your baby is going through and what will come next! In our experience, our baby is ahead of the leaps that the app has designed for his gestational age. However, it’s good to know what to look for and how to help him develop new skills, understand what milestones he is accomplishing each day, or to simply know why he might seem fussier than usual on other days. We cannot predict yet when the leaps start for him as he seems off with the calendar scheduled for him by the app design.

MUST HAVE! Great baby shower gift!. If you don’t yet have the Wonder Weeks app, I cannot recommend it enough. I used it for our 21mo, and it was so nice to know ahead of time when I could expect her to be fussy, grumpy, or clingy. I’m only 25 weeks, but I’ve already programmed baby’s due date (WW works off of due date, not birth date, which the app explains why), and the app has programmed baby’s leaps into my calendar. Normally I cringe at the thought of spending money on an app, but this did prove to be valuable enough, and worth the small expense. App works great, communicates with iPhone calendar, and even has instructional videos that are so helpful.

So cool!. I have really enjoyed learning with this app. It has been spot on and helped navigate the constant changes we’ve witnessed and experienced with our baby. As a first-time mom with anxiety and being very curious about the science behind baby development, being able to read about everything and document what we observe has been really helpful and comforting at times - especially when those sleep regressions hit. A must-have for new parents!

So helpful!. As a first time mom with a baby born at the beginning of covid, it’s been hard going at it with very little help. The Wonder Weeks app has been SO beneficial on knowing what to expect as my little one changes and grow developmentally! I can see what the expected changes are and work with my girl to understand those changes. It also helps me know when to expect those “off” days, and know it’s often nothing wrong other than a bad day. I am very appreciative and think all parents should have this app!

Slow down and appreciate the infant stage. We used wonder weeks with our first son, and are so excited to use it again! It was so incredible to read about what’s going on in “real time”. With our first, the beginning of each leap occurred within 2-3 days of the app! And it helped us really slow down and notice all of the amazing changes baby goes through. It all goes too fast anyway, but wonder weeks helped us understand and appreciate the infant stage so so much. We look forward to the journey with our second!!

Clear info, strategies, and activities. I love learning about the neurological side of development. The Wonder Weeks app gives clear information and activities to help your little one explore their world and develop at their own pace. For my little ones, the timing of the leaps has been spot on. I have actually gone a bit without looking at the app, and if I check in when we’re in a particularly difficult moment, sure enough, lines right up with a leap. And the strategies really help me help my little ones through.

Best new parent app there is!. Such an eye opener into the mind of your child! Highly recommend this app to anyone who is expecting or working with little kids. It helps to better understand your child or someone else’s behavior because of the mental “leap” they are going through and the associated behavior that goes with it. Wish it would go way beyond the 1st year bc I swear my now 4 year old went though a leap right before turning 4. Nonetheless its such a great resource for parents. I highly recommend it.

Love this app!. This app has helped reassure me that I’m not crazy during my baby’s especially fussy times. It also helps me see the light at the end of the tunnel. I’ve used it as a resource for both of my boys, and I’d highly recommend it. Everytime I’ve thought to myself, “My baby seems really fussy, I wonder if he’s going through a leap,” I will check the app and sure enough, he is! The app also gives creative ideas for helping get your baby through a leap without either of you feeling too overwhelmed or frustrated.

Wish I’d had this for my kids!. As a new and jubilant grandma, this takes all the guess work out of raising this little 8-month-old! At least so far the baby has exactly paralleled what the book said was occurring. It has taken the mystery out of why a child seems to back step a formerly achieved behavior. I expect it, understand it, and know it will change. And now that I understand what enormous changes the baby is going through, I don’t feel guilty indulging in extra pampering... just as I would with a sick child. Thank you and I have recommended your book and site to all parents I know!!

Very handy. I have an easy baby, great sleeper but whenever he becomes cranky for a stretch of time and has frequent wakings with lots of crying I would refer to the app and sure enough, it’s a leap. I would check between his due date and birth date because it occasionally varied but overall the app predicted every rough spell we experienced. The more I read on the app the more I was prepared for these leaps. It’s not going to solve your rough spells, just help you understand what’s happening in your baby’s development. Now that my son is in the last leap I wish there was more.

Love the app, but it keeps crashing…. This app was great!…..in the beginning. I’ve been using the app since before my baby was born to write diary entries and add photos as time went on. I als began using it to track his naps and special events that went on in his life. Unfortunately, out of nowhere, the app started crashing. I can’t add a single diary entry or even a nap time because the app crashes whenever I hit save. So disappointed considering I paid for it and I can’t even use it for one of it’s main purposes. Now all I can do is READ about the leaps…i can’t add any signs, signals, pictures, or anything. Very frustrating :(

Very helpful. The wonder weeks app is super helpful in determining when your baby may be learning new things because as parents it’s easy to confuse when they are learning something vs. when they are exhibiting what they have learned. It gives you tips on what to expect and how to help your baby get the most out of each learning “leap”. It can also help you determine why your baby may be more fussy during a certain period of time and can even help you plan ahead for fussy periods around travel, etc. I definitely recommend this app for new parents!

The content is great, if you can find it. The content of the app is absolutely great and incredibly valuable. However, it’s a pain to navigate in the app to find it. The ladies in/put while you are on the milestone app are confusing, you have a scrolling screen, why not put all content there if it’s the same topic? Then you have calendar that you can’t zoom in/out. Then there is MOrE section that has some very useful info, but who would ever go there? Then there are statements like, “check out more about blah blah on ABC of leaps page” where is this page? We absolutely love this app for its content, but you can do a better job at organizing the UI.

Pros & cons. This app is fascinating. I think people are a bit too literal about the dates/ages- sometimes my daughter will be around a week or two late or early on the leap signs but it’s no big deal to me. I think if you keep that in mind, this app is really great. Here’s a list of pros and cons. Pros- It can be ridiculously on point with details and that’s super helpful because it explains a lot of mysteries around your baby’s behaviors or developments when you’re a first time parent lol. It’s also been quite helpful to anticipate leaps and know when the fussiness is coming. It’s been accurate so far. The main con of this app would be that sometimes it will ask questions like “is your six month old walking? Are they understanding what you’re saying yet?” And you can select whether it applies but like… IN WHAT WORLD DOES THAT APPLY TO A 6MO lol. From that perspective, I can see why some people feel like they’re failing after using this app. Overall I like it though!

Latest update renders this useless. Although I knew not to put too much stock in this app, I liked having a place to keep track of milestones and look ahead for upcoming skill development. The latest update added so many nonsensical skills that it's not worth even looking any more. I'm sure some 5-month-old somewhere is walking, but that doesn't mean it's appropriate to include "you walk back and forth," "you make a jumping movement" and "you grab a toy from an overhead shelf or table" for Leap 5. You even include "you oppose your thumb and index finger to grasp small objects", though the pincer grasp is typically a skill seen in 9-month-olds. Your app is bound to mislead caregivers and cause undue worry - it's utterly irresponsible to include skills that are not developmentally appropriate.

Helpful but some skills are waaay off. Overall I do like this app because it helps prepare and know when to expect for a possible fussy phase as well as new skills baby is acquiring. However, I’m very confused about “leap 5” that we just entered. It suggests that baby will say “oo” for “oops” at this age (5.5 months) and that I should “ask if she would like a sandwich when I put her plate down on the table.” Uh, what? She hasn’t started solids yet, much less would be eating a sandwich on a plate. And certainly is nowhere close to saying “oops” when something falls. Up until this point I felt the app aligned decently well with age appropriate skills etc. but this one is way off.

Spot on. I'm on baby number three and this app has been spot on for all of them, even my two premature babies. I will say that the app makes a point to have you put in their due date, but with my premature children, the mental leaps actually happened at the appropriate age from their actual birth dates. When one of my kids is driving me insane, I look at this app and 100% of the time, it's turned out that they're in a leap and knowing that helps me to be more patient with them.

Fun to follow along!. Love this app and the wide range of time of the Leaps and also how they’re very conscious that not all kids may make all these same exact strides at the exact time. I enjoy it to just see where my baby is going next and view the information as a guide knowing good and well I am going to do what’s best for my baby day to day. Once in a while I like to check the app to see how far she’s come or look at a list of possible milestones so I can praise her accomplishments as they happen!

Spot on for both kids!. Our daughter seemed to follow this to a T, and our son is proving to be the same. We don't get notifications from this app so we usually forget about leaps until we notice our child getting extremely fussy and acting different for no reason which prompts us to look at the leap schedule and sure enough it is always spot on, right to the day. The lessons and advice are very helpful in how to navigate these leaps and knowing that there is some sort of explanation somehow makes it easier to cope.

Nice Guideline but don’t take it too serious. I love the app. I’m in a fb group for wonder weeks May babies and I think there is some confusion on skills. Many think these skills occur during the leap but in my experience and from what the app shows, the skills come after the leap. This type of confusion causes worry that babies aren’t reaching milestones. I think this app should be used as a guideline at best to avoid stress/worry. Every baby is different. Let them be babies and enjoy this time while they’re little. They won’t be little long.

Sanity. This app is very helpful, just when you think you’ve lost your mind and think your child is broken, this app brings you right back to reality. Giving you your calm and positive attitude back. Sleep deprivation changes everything. From your thinking, your attitude, your patience. This app really gives you that light at the end of the tunnel. Which in turn for me brings me back from wanting to just give up and thinking I’m a horrible parent. As I stated, lack of sleep, makes you NOT you. This app gets you through it. I love it’s helpful hints and tricks.

Wonder how you lived without it. When we had our first baby I thought this might be a crock but may have some helpful information but it turned out to be right on every time. When it said the baby would be fussy, it was right on. The suggestions for how to entertain your baby through each leap are vital and the information about what exactly is going on in the baby’s brain is so important in being able to understand your child and it definitely makes you feel like a less crazy parent!
