- 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.

- 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.

- 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.

- Good information, bad user interface

The information within the leap examples and milestones is great. However the user experience is lacking. The way the app is organized and the features are laid out is confusing and not easy to use. The same home page has two slides, one details how your child hasn’t entered the leap yet, and the second slide explains what is happening during this leap and both are under the same heading.. Also the checkboxes do not change week over week or leap over leap so it is confusing as to if you are supposed to uncheck them and recheck them? If you uncheck it asks you if you want to delete information. Again, this is confusing so I completely ignore all of these areas and only read about each leap and what happens during each. This app is a good idea but could be executed a lot better to make things easier for parents not harder.

- 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.

- 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.

- 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.

- 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.

- 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!

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- So much support

I’m writing this as a first-time parent. I’m exhausted, overwhelmed, and above all completely terrified I’m going to do the wrong thing and miss critical opportunities to facilitate my son’s development. This app provides timely and useful information that is imparted in manageable and easy to understand chunks. As much as I would love to be able to read all the well-researched books I can find, I don’t have the time. This app gives me information that I would find in those books as it applies to my son in relation to his stage of development and what I can do to support him. I use it almost daily and I can’t imagine parenting without it.


I purchased this app earlier this year and have found it helpful but since the latest update I can no longer see everything I could before because they want me to pay a subscription fee on top of having purchased the app in the first place. This is a really poor way to treat customers. When I bought the app it wasn’t with the understanding I would eventually have to subscribe monthly to maintain full access. If you want to charge new customers to subscribe - fine, but people who bought the app before the subscription should not be stripped of existing access unless they pay more. They should be grandfathered in. Shame on you wonder weeks. Not only will I not be subscribing I will not recommend the app, book or website to any new mom again. Not ok. I will be requesting a refund from Apple for this purchase.

- Best kept secret

This App and book changed our lives. We thought something was wrong when our son was going through a leap. I found the app about 3 months into his development. After the app I knew we were just going through the growing stages of life. Now with our second child, our daughter, it is amazing to be able to remember back the different leaps and compare. Before the app, we felt like WE were bad parents. It was a game changer. Like a light switch. You literally were able to take the pressure off of yourself and give yourself a break. And the book is even better. Highly recommend!!

- 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.

- Poorly designed

This app has GREAT info but is poorly designed and difficult to navigate. Leap information is hidden under separate areas, areas that can be accessed by multiple ports. Just put ALL the info in one place, instead of sprinkling it several places. There is also conflicting information that leads to heavy confusion: the front page specifies when the next leap will arrive, and doesn’t change when in that leap. So halfway through leap 4 it still says “Baby does not make the 4th developmental leap just yet”. Why doesn’t the information update as time passes? Seems like an easy fix that would greatly improve user satisfaction. BUT it does have great info and good tips for managing leaps and encouraging mental development, 3 stars.

- 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.

- 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!!

- 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!!

- 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. !!!

- 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.

- 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.

- 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.

- 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!

- 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!

- 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.

- 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!

- 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!

- 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!

- 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.

- 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.

- So helpful!

For me, hearing “sometimes they just cry for no reason!” isn’t good enough for me. I want to know why! This app really has helped me to understand and sympathize with my baby when he is going through something life changing that I otherwise wouldn’t know he was experiencing. On harder days, it’s much easier to give my little one extra grace when I know that he isn’t just “crying because babies cry!” But Instead because he is going through a major developmental leap. This app helps to explain that!

- Update ruined the app

When I first purchased this app it was wonderful. Very insightful and I even paid extra to purchase the book. I was excited that the upgrade added ideas for activities with your child and more features. I was underwhelmed. It was hard to navigate and the descriptions of the leaps and the developmental phases were lacking. The content was downgraded and the features useless. I still find the leap chart to be useful and we have used the monitor feature. Sadly we will not be continuing the subscription as we can get these features for free with other apps. I am bummed I will be missing out on the book. Hopefully it is still there once the subscription is over as I purchased it before the update.

- So helpful for FTM

As a first time mom, there’s so many unknowns and so much advice swirling around. While I think with everything, every baby is different, but more often times than not - the chart on this is spot on (within a week or two) to when my baby has stormy periods. Knowing when to anticipate these and understand why they’re happening is so helpful. It’s very insightful to understand how my sons brain and life is developing and following along with this app has been very helpful! Highly recommend!!

- Disappointed

Unlike others, I do like the recent update. However it’s a bit disappointing that although I have already purchased the app as well as the book, I now have to subscribe in order to receive all of the features of the app. To me that makes sense for features like white noise and video monitor, but not for content. Before the update the app only included a hint of the content from the book in terms of milestones and characteristics so I was grateful that the update would include more, but it really does not make sense that we have to subscribe in order to receive that information on top of our already paid for purchases.

- Dates on point!

I am obsessed with this app. It shows you, in detail, what your baby is going through developmentally. It shows you tell-tale signs your baby shows when going through each leap. It gives you suggestions on how to calm your baby and also exercises you can do with your baby to promote their growth. My favorite part is the chart that shows you when your baby is going to be fussier than normal. It’s so accurate it’s scary! I would recommend this app to any new parent!

- So helpful!!

Love this app. It’s pretty spot on with the timing of the leaps and it’s so nice to know what our little guy is learning and processing at each stage in his development. I love the suggestions of activities to do that support the leap he is currently in. We literally plan our lives around the stormy/sunny calendar! It’s so useful to be able to maybe avoid planning a road trip when the little guy might be going through a “stormy” period and need a bit more snuggles and attention. Very insightful and easy to use :)

- Not intuitive and redundant

Not a fan of this app. Like other people have said google has helped me far more. It’s not interactive so it’s flat information with the same checklist for every leap. Is that checklist consistent because those are the most common characteristics for every leap? Not sure, because either they don’t explain it or it’s in piles and piles of words. I still don’t know if it’s a checklist or a list of how my baby should feel. Either way it’s the same every leap. From how it’s designed it looks as though your baby is constantly in a leap. The app desperately needs to be redesigned and provide new and interactive ways to receive information.

- Great App for New Parents

I have followed the Wonder Weeks (book and app) for both of my kiddos. It has been really helpful in letting me know what skills they are working on and activities/games to help engage them. The leap alarm has also been a handy feature. The Wonder Weeks give awesome insight about baby brain development, skill acquisition, and the not so fun behavior that accompanies each. I would recommend purchasing the book, as it has a lot of extra information that the app does not.

- So good!

This app gives me so much insight into what my little one is experiencing down to the T! I read through information about each leap with a smile because each time it is spot on. I love the suggestions of activities and games to help support her development and the heads up about new mental and emotional leaps that may come with more fussiness or clinginess. It’s a great tool for new moms looking for in depth information and some direction for helping their little ones grow into creative and well adjusted people!

- I’m not crazy!

This app has been so very helpful in explaining at least one reason why life with DD keeps changing just when a get things figured out. When I realize that her behavior seems to be a consistently new pattern (especially fussiness, sleep regression, Appetite change etc), it is so helpful to check this app to see what might be triggering it besides a physical growth spurt. So helpful to know we’re not crazy, that something really is changing for her — even if we can’t “fix” it.

- Not so sure

I've heard a lot about this app and my friends seem to rely on it a lot. They all said it was extremely accurate. I hate paying for apps which is why I was hesitant to buy it but I gave in because my son, who is 10 weeks, has been super fussy lately, eating all the time and not sleeping well at all and I wanted to see if this app would go along with what he's experiencing. Well it shows that he's currently going through a "sunny" phase but I completely disagree with that. I'll keep with the app for a few weeks to see how "accurate" it is but right now I'm not finding it that great. Please note that I did use my due date, not my son's birthday.

- Highly Recommend!

Our daughter is 5 months old and so far every time she has been fussier than normal or just not acting herself I’ll open up this app and find out she is in a “storm” period. Learning about all the different leaps is so interesting. Let’s be honest, a crying baby is hard- especially when they are inconsolable- but knowing she is in a “storm” period helps keep everything in perspective that this is just a season and will pass soon. Highly recommend this app!

- I recommend this to every parent I meet

I know I should be reading the book from cover to cover. And I did purchase it and the digital version, but since giving birth finding time is rare. So I am so thankful that they thought to create this app which gives me a quick rundown. I can check back and read it quickly anytime to refresh myself on what Leap my Baby is going through and help us better understand some of the things she might be dealing with.

- Not Factual Information

This app and the book it is based on was disproven by the author’s own PhD student. The author acted so indecent after the threat of being exposed became imminent that he was dismissed from education and discredited. This app and book gives parents an excuse as to why their infant is acting poorly, when in reality, babies just cry as part of normal baby behavior. As long as parents are ensuring that the baby is not crying due to being hungry, soiled, or in pain, there is no need to find an excuse for the fussiness. This method gives parents anxiety of upcoming “fussy times” and takes the joy away from parenting and learning with your child. No child experiences the world the same, so it is ridiculous to think that fussiness can be predicted.

- 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.

- 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’.

- 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.

- 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!!

- 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.

- 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!


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.

- 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!

- 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.

- 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.

- 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.

- 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.

- 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

- 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.

- 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.

- 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.

- Using this app for my second baby

It was so good to be aware of when our baby went through a mental leap and what he might have felt/experienced. It helped us understand his world and be more empathic to our baby’s needs. I am now using the app for our second baby! I feel this time round I will be more prepared for the fussy phases and embrace it when it happens.

- 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.

- Wonderful Wonder Weeks App!

This app helped me to cater best for my baby’s needs and to understand what developmentally she was going through and how I could support the next milestones or cognitive transitions. Love the app and highly recommend setting the leap alarm on so you know what to expect and when. I found the activity ideas and videos were helpful!!

- Wonder Week Notes

As a new mum, I have really enjoyed checking back in to the app over the last ten months. The info and bits of what to expect and to look out for are a great help! After my phone updated, I have lost all my wonder week notes... when opening the app today, I had to start from scratch entering all my babies details again. I am pretty disappointed, as I had written down a bunch of his milestones. Is there any way to get these back?

- Fantastic Stress Reliever

I think the hidden talent of the wonder weeks app is that you can not only stop wondering 'why is my child doing this?' But also feel secure that it will pass. When I have been struggling for a few days or weeks I sometimes remember the app and check it only to find it's a leap and I know then that it will pass.

- So much information

Love that I keep discovering new sections of the app with more information and tips. It’s always comforting to receive the notification that our girl is starting a new leap especially when it coincides with her fussy behaviour. Great tips and ideas for activities and ways to help her through each leap as well.

- Accurate!

Love this app, is very helpful to know what's going on with little miss, the timing for the fussy & clingy behaviour is always accurate. Makes me feel less stressed & better equiped to roll with it. I only wish this was around when I had my first because I thought it was something I was doing wrong, very stressful!!

- This is everything.

In a world of so many differing opinions and suggestions, it's so nice to have this app to turn to during the crazy days and sleepless nights. It's been spot on, putting the science back into my babies' development, and a nice and gentle reminder that it's all growth as usual. Now just to keep up with them 😳

- Disappointed

I paid for this very average app , upgraded my iPhone and it’s the only thing that just will not upload from my iCloud back up Also it’s obviously saying things happen at the absolute latest possible time because my twins born early and my niece born right on time are all so far ahead of this app it’s pointless looking at anyway. Honestly just want it to download on my new phone out of principle!

- Pretty good

I like this app- it seems scarily accurate The only thing I wish we could do is write notes on specific days - for instance one day when my bub was being particularly fussy it was during a leap but not a stormy period so I wanted to write it on that specific day for reference. It would be good if you could select a period on the chart and make a note for yourself

- Third baby, still learning!

There has been a lot miscommunication which leads to a lot of screaming from my 11 week old, but this app has helped so much! Third baby and I’m just finding out about phases and leaps, not sure how my first two kids survived! Anyway definitely worth a look for all mums.

- List the start and end dates, not just a countdown

Great update, however it would be nice to also have the upcoming dates listed in the app. Right now it only says how many days until the next leap or how many days until the end of the leap. When you look at the chart it’s also hard to determine the exact start and end dates.

- Interesting concept, but not linked to reality

The app is interesting to read, but in no way linked to the reality of our situation. My friends swore by it, but it just wasn’t even close to what we experienced. But if it makes you feel better to have a working theory as to what’s going on, give it a shot and try to make it fit... for us things just fell apart at random for random lengths of time. I don’t even think we fluked a single alignment with this app’s anticipated leaps etc 😂

- Puts you at ease

Have used for both children and whenever I’ve noticed a change in their behaviour it’s always been spot on that it’s a leap (or a tooth to be fair...). The information and suggestions really put your mind at ease and help you to get through the stage as happily as possible.

- Absolutely spot on!

This app has been amazing! It has been so helpful to myself and my husband, to help understand what’s going on in our daughters little brain. It has been spot on since day 1, to the day. I have been recommending it to anyone with a new bub, it has helped us a lot and is fascinating!

- Amazing

This app was so helpful. It really did make parenting so much easier as we had a better idea what our beautiful baby was going through when there were fussy stages and sleeping issues. Easy to understand and the most useful tool I have come across.

- Wonder weeks

This app is definitely worth the 5$ I paid!! I wish I had of known about it with my other two children! It give me a thorough in depth understanding of why my baby behaves how she does, and the knew skills she is gaining I would recommend this app 100%😇

- Update disappointment

The new app update is riddled with punctuation errors, mistakes and sentences that don’t make sense in the new checklist feature. Considering we pay to get the app this seems like a lazy oversight which I find disappointing. Also frustrating that we have to pay to access all the extra features at once I don’t need/want them all. Should have the option to just pay extra for the extra milestones only.

- Old chart much clearer

Whilst the newer app is pretty, I find the layout cumbersome and the leap chart hard to find. I used the app for my first two children (7 & 4 yr old). Whilst the soft tones are calming, the high contrast old look was better for sleep deprived memory retention - I always feel lost in the new layout. Old layout was easier to find info on what to play with child each leap - new layout has too much wordy science (and I have a science orientated brain).

- A bit confusing.

I put my daughters due date into the app, so it knew she was 5 months old, but some of the things it says do not match her age. For example it said something like ‘talk to your baby. Ask if she wants a sandwich while you’re setting her place at the table’ and ‘play with your baby on the floor, letting them crawl back and forth to you’. She’s 5 months old! Not crawling around eating a sanga just yet. Now I’m not sure which parts to trust.

- Wonderful Wonder Weeks

Such a helpful app! I love knowing where my bub is up to and it helps me understand when he’s not as happy as usual as well. Would definitely recommend to other parents or for those who work with little ones.

- App update is a mess

The previous version of this app wasn’t exactly perfect but somehow you’ve managed to make this one even worse! Since the update I’m unable to click on milestones, the app glitches and gives less information than it used to. I no longer even use it. Maybe next update will be better and I can use it again then. Meantime I’m going to just google it or ask my friends.

- Love it!

I love this app. It’s been super helpful especially when going through a rough patch and not being able to figure out what’s wrong! It’s also so wonderful to read about all the incredible changes my baby is making in each leap.

- Is that what’s happening

I love this app because just when you can’t work out why your little human is really unsettled you realise they are also learning how to do something new. I have loved every moment of this app, we are just on our last leap.

- A Great Help

Has helped so much to understand what’s going on with my kids. I’ve used it for all 3. Sometimes they go through the leap a week before or after (which they state). It’s spot on for the new things they’re learning and their moods.

- Grandmas words

Wow, younger mother this day & age have a great advantage with this app. It would of been so great to have it back in the 70s - 80s. Even further back for all mothers & fathers. 🙂 It is great to read up on & say ah that’s what happening now as we tend to forget though instinctively we know.

- How to share the app with family

It is great to know what gonna happens with baby and how to support him during the time. I just realised lately lots of my friends using it too! Just wonder my hubby downloaded it as it said family can share but he can’t use it on his phone.

- A huge help!

Love this app! It helps me to understand and better cope with the extra fussy periods which entail a lot more clinginess and crying. It is also fascinating to learn about the new skills they learn going through each leap and watching her learn these.


So disappointed with this app and at this price it’s a real rip off. It’s hard to navigate, it’s glitchy and there are even typos! The leap chart will show baby is in a leap but the leap information will say you don’t enter your next leap for x days. You can’t look back on the information once you’ve gone through a leap. So much for a ‘full’ version of the app. Contacted tech support over a month ago and never heard back. Spend your money elsewhere.

- So helpful

This app has helped calm me when I haven’t been able to understand why baby is acting a certain way.. then I check this app and usually it’s because she is in a stage of change. All in all great app !!!

- This app is terrific!

This app has been so useful in helping me to understand the cognitive development of my boys. Admittedly, they have hit all of the leaps earlier than predicted by their due dates but as a rough guide, it is invaluable for detailing behaviours and helping me to sympathise with the fussy periods. Thank you so much!

- Great insight

App is great. Details what your baby is going through and developmental changes you might expect. Would be nice to be able to add notes for each day i.e. it says he’ll be fussy on May 20, provide a calendar to detail his behaviour to compare to the Wonder Week details.

- Avoid the new update

This app used to be very good and accurate. Today, I’m disappointed to find out that this app’s new upgrade withholds lots of information to users who already paid the initial fee. If you want to understand the leap properly, you have to keep paying expensive subscription fee continuously, not worth it anymore. If I knew this, I wouldn’t have even paid the initial fee. I would get a different app instead.

- Wish Start/End Dates were displayed on the chart

When I click the bars of each leap, it’ll be good if it shows the date range, as it is quite hard to make out from the chart exactly which date it starts or ends.

- 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!

- 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.

- 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.

- Great app

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

- 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!

- 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!

- 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!!

- Not useful

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

- 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.

- Useless

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

- 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.

- 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.

- So accurate!

10 months old and this app is still always so accurate, it’s almost scary!

- Confusing Interface

My wife and I check this App occasionally To see when our baby is going through leaps, but I find the app overly complicated and the interface is not user friendly or intuitive. I also find that the wording is very confusing - for example the wording of the checklists for each leap. I don’t particularly understand why each one starts with “you”. “You are bad tempered, you cry more” - I get that it’s directed at baby but personally it would more sense if it was directed at the baby in third persons. The last item on the checklist is “I’ve noticed that you”, and that’s it - no further explanation on the checklist. I imagine your suppose to edit it and write your own comments but I personally find there is a better way of doing it. Overall I would say that the information is good, and might help put parents at ease, but I wouldn’t recommend it purely on the fact that it’s UI is terrible. I’m much more likely to check google.

- Super annoyed

I got this for a little knowledge (even though it’s all google-able) but also for the added white noise. But once you pay the $5.50 for the app they then want you to pay $17.00 to have the “more” page for 6 months.

- Paid for app and app is not opening

I paid for this app and not long after the app is not working anymore. I sent an email for support and am not getting an answer this is super frustrating, what a waste of money.

- So reassuring

I can say a lot of stuff that everyone else is saying so I’ll tell an anecdote instead. My 2 month old has been very stand off-ish with my husband lately and he’s been really bummed about it. I tried to tell him that it was normal that she would be clingy to me but I think it didn’t really sink in for him because he thought I was trying to make him feel better. Not a day after we had that conversation, I get an alert that my girl is hitting a leap and one of the defining points was that she would be much more clingy to me and shy with everyone else. I could see a weight lift off of my husband just having that reassurance that this is normal and temporary and happening exactly when it does for just about everyone else. Thank you for making our newly chaotic lives a little bit less anxious.

- Understanding your baby

Although this app won’t solve your problems, it will help you understand what your baby is going through and give you the encouragement you need to get through the phases. It did wonders (pun intended) for us to expect the worst and look forward to better days. We also knew a little bit better how to approach the different phases.

- Very informative

This app is great and definitely teaches you a lot. Any time my baby is acting out of sorts I check this app and it almost always lines up. I’ve learned a lot and it’s actually really interesting. Definitely helps you to know what’s going on with your little one and know less fussy days are coming! They also have great customer service... I had an issue with my app and they reached out to offer assistance right away.

- Very helpful

This has been a great app I’ve recommended to all my mom friends

- Interesting info, hard to navigate

The UX of this app sucks, I recommend buying the book instead.

- Maybe needs an update?

Most times the paragraphs telling you what’s going on with baby is cut off at the bottom and I can’t scroll down to read it. Defeats the purpose of the app. And his leaps add up when I use his birthday, not due date..and even then they are still slightly off.

- Dommage....

Pour commencer, la traduction en français est une vraie catastrophe. C’est limite illisible. Quand on paye ce prix, on s’attend à une traduction efficace... ou ne proposez tout simplement pas l’option en français. La navigation est très peu fluide. Difficile de s’y retrouver.... On a également la sensation que les semaines se ressemblent toutes. Les signes qui montrent qu’on est dans un nouveau bon sont quasi-identiques. Dommage car le livre est bon, il y a avait matière à faire quelque chose de génial. Mais la cible est manquée... Je ne recommande pas.... écoutez plutôt votre cœur de parents et regardez votre enfant au lieu de lire une app ;)

- A hot mess of an app

What am I even looking at? Nothing is placed in a way that’s easy to comprehend. More confused than anything else? Pls make more user friendly

- Insightful and helpful

This app was very helpful. It is a great guide to help you navigate through all the developmental stages of your new baby. Every baby and child is different and unique, but having a guide gives you the confidence to figure it out as you go along. So thankful for the wonder weeks!

- False (or at least misleading) advertising....

To be fair, I've yet to fully explore this app, so perhaps I'll find enough content to justify the price (in which case I'll update this review).... However, the stickler in ,e was annoyed right off the bat by the misleading implication that the book was included in the app, when it is not. The app description lists its 'key features' followed by its 'extras' -- perhaps I'm misinterpreting that, but I would assume that's referring to 'extras' included in the purchase... similar to a burger on a restaurant menu that's described as having 'extra cheese' (as opposed to the list of toppings at the bottom of the menu that are labeled as 'optional extras' or a type of 'upsizing'. Therefore I was a bit perturbed to find that immediately after launching the app I was prompted to enrol in an optional $4/month subscription service in order to access the aforementioned features. Again, I haven't fully explored the app or read the source book, so perhaps those resources are fully worth the monthly fee and then some, and of so I would happily pay it..... I just don't like the fact that the additional costs were sort of hidden or at least purposefully worded in a vague way.... Ok, now I'll dive into the app and return to give an honest opinion of my experience, but I just wanted to first put my initial impression on front street. Oh, also, as a first-time user just starting out on the app, but with a child that's already 6 months old, it's not super easy to jump right in. There is a tutorial, but it mainly lists the features, whereas I'd love if it gave some guidance on how to start using the app -- even more so if it that guidance was applicable to my child's age at the time I was signing up (seeing as users have to supply their due date anyway, why not use that info to curate more relevant info for your clients?)

- Great reminder to stay calm!

Awesome tool to mentally prepare for the rough days and the not so rough days of newborn life!

- Great app

My wife and I just had our 2nd daughter. I loved using this app with our first born, and now with our second I’m looking forward to using it again. BUT PLEASE......spell imminent “imminent” and not eminent. On the tab “leaps” under “leap alarms” the app asks if I want to get notifications eminently. That’s like asking if I want notifications famously! Please correct this word! Otherwise awesome app 🤗

- Read.

I thought this app was for something else and bought it, may I please have a refund

- App giving conflicting info! Terrible customer support!

Don’t waste your money!!!! This app gives me one info on one page and completely opposite on another. First page says “baby does not enter # leap for another “x” days...” while the calendar and page 2 clearly show him in that leap. I contacted their support Center 3 times requesting either help or refund and they completely ignored me!!!! Shame on wonder weeks! Wish I can give them ZERO stars!!!!

- A good tool for parents

Text is a bit clunky and many of the videos are crap, but this is still a super useful tool to help understand why your baby is freaking out and get interested in what is going on for them.

- Content good layout bad

I find the content of this app good, but how it’s laid out is very confusing. It’s hard to know where I am in the app or even what other content there is for me to see. Sometimes I can’t tell which leap my baby is in because one page say it is supposed to start at a certain week but another page says something different.

- A lazy and sloppy app.

This is a terribly produced app. Information is hidden everywhere, duplicated, with odd broken links frequent, missing items, poor grammar, and no flow. It has one of the worst UIs I have ever encountered, for what should be a straightforward thing (basically a book summary). Sections mention ‘lists’ that simply aren’t present... after digging around you find they are part of a $35/year subscription. It’s a cash grab that’s extra frustrating because it’s so incompetent. Using this app is like eating a meal where there are too many dishes and none are cooked well. No idea how the rating is so high. Maybe people like the concept? Perhaps it’s an interesting way of understanding development, but the app itself is hot garbage. Skip out on this one!

- They seriously need to hire a proofreader...

The explanations that come with each developmental leap are very poorly written. And on top of the sloppy grammar, it seems to me like they just fill space by repeating the same explanations over and over. I really expected this app to contain real information written by educated individuals. But really, it’s just a bunch of fluff written by someone with only a tenuous grasp of the English language.

- Vague and Hollow

My wife and I agree that this has been one of the most disappointing investments we’ve made in any baby information source since our little one was born. Now 6 months in the leap info states nothing but generic, repetitive information. This is a lot of lipstick on a pig. Buy a book instead.

- Not accurate, poor customer service

I don’t find these dates correspond at all to my baby, and from talking to other parents it sounds like they’re pretty inaccurate too. The leap windows are so long that you can pretend any crankiness or fussiness is leap-related. Also emailing customer service about an app tech issue took over a month for a response. Don’t waste your money.

- unhappy

Waste of money.. none of the features I wanted noise machine .. wifi cam etc even come included in the cost. I want my $$ back

- Inscrutable and internally inconsistent

I can’t understand what this app is for or who it helps. Terribly designed and completely confusing.

- Don’t understand the hype

It’s really not helpful or worth it.

- You pay for app then you have to pay for more once you have the app

I find it very frustrating that they give you minimal information and then expect to pay again for more. Usually the app is free in those instances so you expect it but in this case the app wasn’t free. The amount of money they want is not worth the information they provide in my opinion.

- Great info but don’t like the redesign

Super helpful in figuring out wth is wrong with my baby. I refer to it during fussy periods, and sure enough, he’s going through a leap! However, I don’t like the redesign of the app, it’s not as well laid out or as intuitive as the previous design and I find myself scrolling through different menus trying to figure out what I’m looking for. Also I can’t imagine paying $15.99 for 6 months for the upgraded plan. It’s good, but not that good

- Broken

My app doesnt seem to make sense, it said 4 days until end of leap but in the description says Molina osnr due to make her 4th lean until 27 days... ive tried to delete the profile and make a new bit it doesnt seem to work. How can I fix this? It’s been like this for the past month.

- Quelques bugs

Quelques bugs , par exemple au bond deux je n’ai pas accès a voir les étapes que bébé est supposé franchir, on voit seulement les codes (milestones_01, milestones_02) parfois il y a aussi des erreurs dans le texte par exemple : vous pourrez découvrir (his or her) caractère. Ce n’est pas grand chose mais c’est quand même décevant pour une application payante. Le contenu est fort intéressant

- Amazing app

This app is amazing! Every time it’s spot on with my babies changes and then their new skills. My friends and sister also use and enjoy this app. Very helpful to know why your baby is more fussy, crying more etc. And it is so helpful to read and understand what their little minds are going through. Highly recommend for any new parents!

- Borderline scam

It’s the same information as is found for free on their website with the option of buying a subscription for (hopefully?) more or better information. Found nothing on this app that goes beyond the most basic general knowledge of baby developmental milestones and only in the vaguest terms. The calendar feature is an uninformative decoration. Deleted app within a couple of hours of downloading. How can I get a refund for this?

- Helpful

As a new parent this app eased my worries and answered many questions. It helped to make sense of things when my baby’s temperament changed unexpectedly. I love the fact that it gives you tips on how to get through each developmental stage.

- This app is a promotion to a book

This app is a promotion to a book they try selling you. So first you purchase this app and then the app is designed to promote a book for the actual info.

- Language settings

I downloaded this app and the language preferences are requested for verification every time I open the app. This would be fine however now the language has set itself to polish and I can’t get the app to open up to the language setting page anymore to select English. The user interface of the app is not very appealing. There’s a lot of good information but hidden in different tabs or sections that doesn’t make sense. There’s also a lot of repetition across tabs. Would encourage them to re categorize their information and work sign a better graphics team to accomplish a more user friendly interface . I have used free apps with better structure than this one...

- Does not match with my kid, makes no sense

Doesn’t match up with my child at all, and when I contacted support asking if there was a way to fix that because possibly I had made a mistake, but I got no response. Really sucks I spent money on this, I could have used it for something that is actually useful. That’s the only thing I learned 🤷‍♀️

- Overall a decent app but some issues

Overall this is a decent app that provides information to help you understand your baby’s cognitive development and behaviour. It is frustrating though that there are several mistakes in the text. For example this week’s info which goes back to the previous leap (Leap 2) instead of telling me what to expect following this leap (Leap 3)... would be good if developers could go back through and clean up these mistakes.

- Nice

Very nice app, informative and educational. I like the things they tell you about each stage and the suggestions they make. I felt like it was especially handy during this first year. My one disappointment was that when I got a new phone, all of my notes and info didn’t travel over to it with the app; instead I had to start all over again, uploading her pic, due date, etc. Those notes I wrote about my baby are completely gone.

- Does not make sense

There are glowing reviews for this app, but it does not make sense to me at all. I’ve tried switching it from due date to my daughter’s actual dob but it still has things that don’t make sense. For example. It said my daughter starts next leap in 8 days, but in another area says leap 5 does not take place until around 26 weeks/6 months. My daughter is not six months for another 4 weeks/month! How does this make sense? When I tried via her actual due date, it said she was in leap 4, but in the paragraphs below, said “_(daughter’s name)_ does not start leap 4 until..” I’m so frustrated. No one can explain to me how this app works.

- Stupid

This is the most stupidest thing I have ever heard of. It’s growth spurts not leaps. Leaps just sounds odd. I guess I’m old school but I want a refund as I thought I would get more out of this app than learning what a leap was. It’s a dang growth spurt so nothing new. Still waiting on a refund. My baby has not done any of these said things. Please refund my money ASAP. Please save your money people this app is of no help at all. They can’t predict when your baby will do these things. My baby is 12 weeks and he has yet to go through leap 1 & 2 from these statements. Therefore non of this is true. Yes my baby was born on his due date so I’m on the correct time frame. Stop making up crap to get people to buy this app that isn’t true.

- Comes in handy for any parent

I recently became a mom 3 months ago, and had NO idea babies had “mental leaps”, even less that they are quite often. One day I had a very fuzzy 5 week old, and desperate to understand why I came across this app. It’s simple, and easy to understand. I’ve noticed that not many people know about Leaps either, they just asume baby is having a bad week and fail to realize that it’s so much more than that. 100% recommended

- Not worth it

The only thing you will use in this app is the calendar and you can make one yourself if you really want to. The home page information is confusing because it tells you briefly about the upcoming leap but somehow by the end of the blurb you realize it’s talking about the last leap. You have to go into the “all leaps” section each time to read about the one that’s coming but even that is annoying because they are labeled by the number of weeks your kid will be at he end of it. I just want to read about the 5th leap not the Leap of the 26th week. Besides my kid is not going through these on time anyway so it’s not even relevant. Oh yeah and the videos don’t work.

- A must have for moms!

I read The Wonder Weeks years ago when I was a newer mom. It was so eye-opening and great to have all of the updated information at the touch of a finger. Learn all about the inside and outside growth spurt’s that babies naturally have that could cause them to act differently than normal. I highly recommend it for new moms and seasoned moms! This app is full of great educational information, tips, calendars, and real help for getting through fussy times with baby.

- Meh

Maybe it’s the fact that I just have a high needs baby, but I don’t find this app particularly helpful. I guess for an app that’s not free, I was expecting more in-depth information regarding each leap and ways to help baby through while also saving my sanity. I’m bummed I spent money for basically the same info I can find easily on google for free, because I’ve referenced google way more often than this app. The timeframe for when baby is expected to go through these leaps seems pretty generalized and I don’t see the value Ain something that says your baby might be going through this right now, but they also might not be...

- If you have a a new baby, you need this app!

This app is spot on every time my child enter a new leap. This app allows me to have a better understanding what is going with my child and what he’s struggling with or what he’s going to learn to do next! I as a new mom can cope with how my child is doing and take a step back and help my child get through this leap, without feeling frustrated or stressed out when comes to my child and he’s leaps and the many moods he has.

- Great info but..

I absolutely love this app due to the scarily accurate info it gives me for my baby. I feel fact, it’s the only app I have ever PURCHASED. And adamantly recommended to a friend that is expecting. However, I was extremely disappointed to open it up after this update to find that an app I already paid for wanted me to now pay for a subscription. I also don’t enjoy the layout of the app as much as the previous version. I gave 2 stars because I do think this app is extremely helpful for parents and caregivers. But, I don’t like that I’m not being asked to pay for something I’ve already paid for.

- On point

My daughter has hit every fussy stage almost to the day. It makes me feel so much better since she’s my first that I don’t have to rush her to the doctors every time she’s cranky because the app explains that it’s her cognitive leaps or learning separation anxiety or just moodiness so it’s such a weight off and I can see when it ends too! It gives me a light at the end of the tunnel. This app has been absolutely wonderful. I’m just sad I didn’t have it from the day I brought her home!

- Wonderful!

This app is amazing! Just about every time my little one is being unbelievably uncooperative and it doesn’t make sense. I check and sure as heck he’s going through another leap! It helps me to keep my cool because at least I understand what is going on and that there is an end. It is incredibly fascinating to learn what is going on and understanding what new things they are learning and when! You’ll appreciate the things you learn from this app.

- This app is AMAZING!

I didn’t know about this app until my first was around 6 months old. It is totally worth the $$. It is SPOT on. Like for instance my daughter is currently 7 weeks. She’s not currently going through a leap but estimated by her due date they say she may be going through a “stormy” or tough time for the next few days and that’s exactly what has been happening. Sleepless nights. There is mounds on information on this app. It’s absolutely incredible. MUST HAVE

- On point!! Kept me sane!

This app was so amazing. I got it for my first baby and used it for my 2nd. Both times it was on point with the times of regressions/leaps/milestones. The signs and changes to look out for. When my baby would be waking up all night or napping/eating poorly, I would notice the app was on schedule saying the same exact changes! It kept me sane knowing that it would eventually end and it was just a phase. Definitely recommend!

- Confusing Home Screen

I’ll start off by saying I really appreciate the leap chart and how it tracks where you are and when the next leap is. However, I’m giving this 3 stars because the home screen is very confusing for myself and I’ve heard from countless other moms. Often times the app will say you’re in a leap with a certain number of days left but the text down below will say that your child is not at the next leap yet. I found out that you have to swipe right to get the updated info, but it shouldn’t be set up like that.

- Helpful to keep you sane during leaps

I’ve now used this app for two children and it has been spot on. It prepares me so I can expect a crabbier child. Takes some of the guess work out of raising babies. The only negative I have is they stop at leap 10! I know kids go past but they just don’t offer that information. We’re currently on Leap 10 with my second child so after I will not be needing it anymore but I recommend it to any new mom!

- Great tool

New parents! You need this app. It’s worth the $3. Reading up on why your kiddo gets irritable or fussy helps you understand what’s going on in their brains, therefore making these stages less exhausting and frustrating! Well set up with bullet points, videos etc that all help make this info easy to digest when sleep deprived and busy with a little one. Love the alerts that connect to your phone so you know when they’re about to enter a new leap!

- This is a must have app for any parent of an infant!

I love the book, but it can be difficult to grab hold of it when the little one falls asleep in your arms, while reaching the phone in your pocket is so much easier. It was incredibly helpful to learn about my child’s development and it was even more delightful to watch her grow after I had this knowledge. This app also helped me expose her to appropriate play and learning opportunities. Can’t recommend enough.

- Pseudoscience

Where are the references to the EVIDENCE and SCIENCE behind everything this app is claims?!?! This is total pseudoscience and a gross attempt, albeit successful, to get my $4. It could at least be entertaining to use, but the app is very confusing to navigate. The same information, but slightly different, is on multiple pages. The same checklists are on multiple tabs, but the checklists don’t “talk to each other” so different things are marked off on each checklist. Also, it clearly states that you must use the due date, and gives the example of preemies, but what about for babies born after their due date?—it makes no reference to this. Overall, disappointing.

- Worth the money

I was hesitant to purchase this app at first, but finally did after several friends swore by it. So far it has been spot on with my son and his fussy periods. It helps keep you sane as a parent because you know when to expect a fussier/clingier baby & it offers helpful suggestions and insight. With my first, I always thought it was something I was doing wrong. Now I know that these are leaps that all babies go through! Love this app!

- Helpful but glitchy

The information itself is useful and has lined up pretty accurately with my son’s due date, even though he was born 3 weeks early. However, the app seems kind of glitchy (verified with other users as well). When he was mid leap 2 the countdown in the app correctly showed “8 days until end of current leap” but the text said “22 days until leap 2”. If all I needed was a correct countdown I wouldn’t have purchased the app. Hoping it can be fixed soon as the app isn’t very useful without the additional information.

- Format Change Ruined It

When my son was born in June, I found his app incredible useful. It provided examples of what to expect, was concise and easy to use, and even had video examples of what he might be experiencing. Now all they have are endless checklists of useless crap that don’t give you any idea of what to expect - just an endless amount of data to fill out and super minimal information with additional reference to some book. It’s like they went from providing information to collecting it, but not for my information or assistance. I find it essentially useless now and have recommended against it when a half dozen or so friends have asked about it.

- One of the best things ever

There were times when I was pulling my hair out trying to find out what was wrong with my twins & why they were so fussy. Then, I would check the app & have this ‘Ohhhh’ moment. I can always track when there will be more fussy periods for them. We’re coming up on the 10th & final leap & this app has been right there with us the whole time. I recommend it to all of my new parent friends

- It’s okay

It helps me see vaguely what my baby is going through. Navigation is clunky, and it doesn’t account for variations in development pacing between babies. In talking with other parents, people have found it confusing and frustrating when their baby’s behavior is slightly off this curve. The writing is hard to follow, mostly due to the clunky navigation. Depending on the section you’re on, it can be unclear whether what your reading is general leap info or specific to the leap you’re in. Some of it is very horoscope like in terms of being vaguely applicable to any baby at any given time.

- Disappointed

When I first had my daughter everyone raved about this app so I gave in and got it. I followed the directions and went off babies due date and not birthday. Well so far every single leap has been off. We have been through 3 leaps so far and every time she has had them at the time that would line up with her birthdate and NOT her due date. The more I have spoken with other moms of early babies they have told me their little ones didn’t match up either. I still keep the app to see what the next leap includes but I take the predictions on cloudy and sunny days with a huge grain of salt.

- Gift of insight

This app has given me the gift of insight into my 2 little ones and their world. The understanding has been amazing when it feels like what was settled becomes crazy, what we had established is undone, and we work through a stormy time. I love knowing what is being learned at each stage so I can be sensitive to it and their development needs. I highly recommend this app as an awesome bite-size, amazing gift of insight into my baby’s world.

- Don’t recommend!

If this app had a free trial I wouldn’t have bought it. I bought it in a moment of frustration because I can’t understand why my baby is so fussy. The language is not easy in this app. They use technical terms which they didn’t provide explanation for. The app is poorly organized and difficult to navigate through. My baby has been fussy for a few days and the app says he’s starting his leap in two days! The app deals with babies as if they are all the same, have the same development rate and achieve milestones on a specific day which is completely untrue.

- Was awesome until recent update

Like most other reviews, I LOVED this app until the last update which requires you to pay for full summaries. These full summaries used to be included with the price of the app; however, now the developers seemed to change it to find ways to make more money by asking you to buy the ebook or audiobook for the full summary. I used to give it 5 stars, but now I want my money back after this change. :( Update - the developers have replied to my request denying any changes occurred even after I provided them evidence of paid content previously being removed. Poor customer service.

- So helpful!

It’s a paid app, but in my opinion, it’s well worth it. It lets the user know when each leap in development is happening, and describes in depth the signs, the moods, and the new abilities. It even suggests games to play with your baby that are appropriate for each development phase. It has really helped me identify when my baby is approaching or actively going through something, and prepare for behavioral and mood changes that accompany it.

- Amazing baby tool!

I originally got this app when I had my son. It was recommended by a ton of moms in a mommy blog I was reading. I was a little iffy about how true this app could be. I was amazed one day when my son was acting fussier than normal and a few minutes later I got a notification that my son was in a leap! This app is so true to every leap he went through. Now I have a two month old and using the app with her. I love it!

- Priceless info!

My baby would suddenly change behavior or sleep patterns but I didn’t know why and it was driving me crazy and making me feel like I was doing something wrong. Then my friend told me about this app and it was a lifesaver. It explained all of her development milestones and the changes she was experiencing. I used her actual birthdate and the timing was exact. This is the best tool especially as a first time mom!

- Thank you!

I read the book, and bought the app for its connectivity with my calendar and up to date information that I can easily share with my spouse. We travel often, and the babywise app helps us to understand what our baby is going through on the days we plan to travel! Will we need to have extra patience with her, or can we expect an easy, sunny baby? 😍

- Must have app

I highly recommend this app. I waited to buy it based on a few negative reviews, and finally bought it after a number of word-of-mouth recommendations. I wish I had it sooner. It has great advice for each stage babies go through. The “fussy phases” timelines are also a huge help. This app is a must have to better understand the cognitive development of your child day-by-day and week-by-week.

- Don’t totally agree...

I don’t think my kid has his leaps according to due date at all, but it’s dead on for his birth date. Great to know what he’s working on and when and why he’s grumpy!! It would get 5 stars if I (and several friends) found it accurate to their insistence of due date. I just created a second profile for him with his birth date and that’s how I discovered his schedule is more accurate with birth date. So if you feel like it’s off a bit, try that!

- Doesn’t keep info.

Every time I reopen the app I have to re add my baby. When I try to take pictures the app closes and of course when I re open I have to re add my baby. Very frustrating since I can’t keep notes and keep track of what my baby is doing since it isn’t saving any info. Waste of money. So sad since I loved it when using it with my first daughter 6 years ago.

- Brilliant app with deep insight into baby

This is my second child, but first child on the app. I absolutely find this app to be essential in tracking my child’s development. If you’re looking for a deeper understanding into the inner workings of your baby’s development, this app definitely provides everything you need to know. User friendly and engaging, the Wonder Weeks app makes tracking your baby a breeze!

- Same information for weeks, not actually helpful

I have so many friends that recommend this app and after using it, I can’t understand why. The same information about my son “not being in a leap” yet is there for what seems like forever. It is constantly the same information/page for weeks. My son is going through a drastic change in his sleep patterns during the night, and when I check to see if there is any useful information that can sort of explain what’s happening, nothing. Such a waste of money and phone space. I don’t recommend this app at all.

- Not worth the hype

I wish there was more to the app, they don’t update anything for all of the leaps, it’s the same messaging for the entire leap and a mediocre checklist of a few things your baby COULD be doing at this time. You’re expected to input your own notes, but I don’t think anyone needs an app to keep track of their baby’s milestones. The calendar is hard to read (I’m a designer, it could be much better) and the user experience is not great. I never buy apps and this one confirms my suspicion. Not that impressed, I hope the book is better.

- Helpful BUT...

I really enjoy this app. It definitely helps explain what my daughter’s going through. My only complaint is that I wish we could decide when to unlock the leap. My daughter is in her third leap now and with each leap she has started 3 days early. I can now easily tell she’s in a leap, but wish I could have the info when she starts instead of having to wait 3 days until the Wonder Weeks says she’s going to start to know what’s going on.

- Incredibly helpful app

It has been so helpful knowing when my baby is going through a leap, the new skills she is learning, and how I can best support and encourage her. Having a chart showing anticipated leap dates has helped me plan some quieter times during her “stormy” days. It also helps me keep in perspective that her fussing has a purpose and it will pass. Thanks for helping me parent a little better, Wonder Weeks!

- Definitely a must-have app for new parents

As first-time parents, we really appreciated the great insights this app had as we navigated the first few months of our baby. Moreover, it gave us plenty of peace of mind knowing that all of this has bona fide research to back it up. This is very important given all of the unscientific research, articles and books that “advise” you to do things that will have lasting negative consequences on your kid.

- A must have!

This helps so much! Your baby is not broken or bad (of course I knew that but begin thinking what’s wrong with me or my baby after fussy/ clingy/cranky/ regressing type behavior). Nope- baby is healthy and just going through leaps and growth spurts and this has helped me feel more confidant as a new mom and helps me prepare so I can help baby and now I know that these behaviors are so healthy and a sign of growth. Love this app so much!

- Best app ever!

Love this app! It has helped us to know what to expect for our baby. Parenting is exhausting enough, but when your baby is fussy and you don't know why it can be very stressful. Especially if nursing, you start to think you are doing something wrong! This app shows you why they are fussy and even gives you ways to help them through those fussy times. It's like an angel sent from God! 😂🙌🏻

- Fantastic app!

This app was the most helpful for this mom of 2. For both kids it helped guide us through developmental milestones and make us feel better during the stormy times. We weren’t doing anything wrong - each time our baby wouldn’t sleep or would be overly fussy we’d check the app, low and behold we were close to entering a leap! It’s amazing how spot on the milestones were!

- Horrible new update

The new update is horrible, layout looks fancier but harder to find the things that used to be easily accessible. Now they try to get you to do more in-app purchases just to check off things your child can do etc. Very disappointed. Never had this app with my first and honestly just googling each leap got me through it. Upset I wasted money on this. Also a lot of the skills each leap states your baby should be doing is quite out there for the age of the baby. “Puts food in someone else’s mouth” at age 4 months?! Come on, they are just learning where their hands are.

- Upgrades aren’t always a good thing

I bought a great app. Then it upgraded an app that is one giant ad for the book... so I paid to be advertised to. Nice ploy. I still struggle to see what these leaps are in my child, there’s nothing remotely similar to the described behavior anywhere near the times they list, and support for dating questions has been paltry at best. It’s still good information about development and skills my baby is learning, just because it doesn’t come close to describing my child certainly doesn’t mean it’s wrong. I’m fairly angry about the huge loss of info with the update though. Crappy move.

- Subscription change.

I bought this app a couple weeks ago, paid for it, and absolutely loved it the way it was! I loved that it gave you signs and ways to help them through a development. It was simple, easy, no ads, or crazy unlock features. I told three friends to download it. They were all so pumped! I opened it yesterday and got quite angry. After already purchasing it, they now changed it to a monthly subscription. They took away all the features I loved and made it basic and flat, but you can unlock more stuff for a monthly fee. Like... really? That was a kick to the gut. Thanks a lot.

- Not updating, and can only contact support through configured email

I had heard great things about this app, but unfortunately it stopped updating. My baby is 4 months currently, and there is a leap at 14.5 weeks of development, but it’s still telling me that it’s 38 days away. I went to contact support about it, and they only have one method to reach anyone - that’s sending an email through configured email on your phone. They don’t offer any other methods for getting help. I do not want to add my email to my phone, and now I’m stuck with an app I paid for that won’t update and no way to reach anyone.

- Extremely confusing

This app is very poorly designed in terms of how information is organized and presented. Nothing is intuitive or clear. I went to the Wonder Weeks website to see if I could get clarity and it is no better! Also the app is full of typos and inconsistent language. For example one page says “look on the milestones tab.” But there is no tab labeled “milestones.” There’s a tab labeled “Leaps” (Is that what they mean by “milestones” tab? Who knows?) but the info I was looking for did not seem to be there. Very frustrating. $3.99 is not a lot of money but I’m still sorry I paid for this.

- Spot on!

I was skeptical about buying an app claiming they know what’s going on in a baby’s development, but it is spot on with my daughter! Right around the tome she is entering a “leap,” we can tell she is a little more fussy and it makes sense why! So much is happening in her little world! It’s so great to be able to understand what she’s going through and have the peace of mind knowing we aren’t doing anything wrong.

- Update ruined the app

I had this app and absolutely loved it before the most recent update. The update took away most of the leap information and wants you to pay even more than the original app price to view the “typical leap signs.” Disappointing. I loved this app to track my daughter’s leaps and found it to be spot on in regards to her development, but I’m unimpressed by the apparent need to charge even more to use the information. They totally redid the interface as well, and I think the old layout was much easier to navigate. I had recommended this app to a lot of new moms but will no longer be doing so.

Sickening and no wonder why Labour won’t be elected any time soon... When the death of 4 people has occurred within a matter of weeks, she tweets this bile? #LabourDisgrace

Wheezy Anxiety Dog. 🐕

By the way, I have no wifi other than on my phone so if you're wonder why I haven't been posting any art that's the reason! We should break getting internet here in the next few weeks so fingers crossed!

You have to wonder, was it the steady 20,000+ cases for weeks which prompted a new lockdown or a single opinion poll this week.
