- Nothing more then baby astrology

This app is a waste of money. Wonder weeks has been disproven over and over again. Babies are fussy and crappy sleepers. Welcome to having a baby. It has nothing to do with these so-called “leaps”

- So accurate!

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

- 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.

- 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!!

- 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.

- Interesting info, hard to navigate

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

- Not useful

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

- 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.

- 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.

- 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

- Useless

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

- Very helpful

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

- 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?)

- 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!

- 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 🤗

- 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.

- 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 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.

- 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!

- 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.

- 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.

- Read.

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

- 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.

- 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

- 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?

- 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!

- 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...

- 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.

- 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.

- 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.

- Terrible Update

The newest update is absolute crap! It is not user friendly at all. A lot of the information content has been removed and “examples” are provided (where they say for more in depth examples go to the book...which there is no longer access too) and short leap descriptions; before it went into really great detail about the leaps. The new checklists are useless! Now to get any of the previous features you have to pay for the subscription service, which actually will cost about 3x as much as just going and buying the book! A 6 month subscription for 16$ for something that you theoretically use for 2 years...umm🤔 When I bought the app, there was family sharing, easy diary entries and access to the ebook, now none of that is available! The diary is hard to use and understand. You can easily look up all the provided information online elsewhere. The only useful feature left is the calendar showing when the leaps are expected to occur! So disappointed! Don’t waste your money, just go buy the book and do yourself a favour!

- Au top

Facile, aidante et amusante. Je la conseille

- Has gone downhill

Newest update is terrible. Not only was it a tactic to make users pay more, but even basics like spelling and grammar in the content you do receive is not correct. Unless you want to pay for all of the features - don’t bother. All the information is easily found in other sources online.

- Like the app but..

I bought all the extras on the previous version and shared via family sharing with my husband and now they’ve added a ton of paid features, changed their family sharing policy to disallow sharing of in-app purchase (basically meaning no family sharing). Not cool!

- Terrible

Since the update in September 2019 it basically doesn’t show anything. The information provided is generic and doesn’t provide any detail as to skills and milestones as it did before the update. It now requires a “gold” membership to release the info even though I already paid to download. DO NO PAY FOR THIS APP. The Internet moms can give you better info on development than this app

- Monitor not working properly

I used to love this app and it’s extras (with purchase of subscription). I am disappointed that the monitor no longer works for me. A second after I scan the QR code and connect with the other device the connection is lost. I thought it would be okay to leave the monitors at home and use this while on vacation. That is not the case. I do love reading the e-chapters and find them interesting. Some of the comments from other parents have me raising an eyebrow sometimes though.

- Buggy App

The “more” section of the app does not open. I bought the app specifically to get access to suggested activities, which is under the “more” section.

- Promising but very limited, not worth the cost

I really wanted to like this app, especially after a friend recommended it (she used an earlier version which I understand to have been better). Given that I paid for it, I still use it but honestly, it’s poorly written, repetitive, and doesn’t make a lot of sense. The “leaps” bleed into one another and information is all over the place. Honestly, everything could be gleaned from a basic internet search. Lots of potential but for a premium app, immensely disappointing.

- Vastly Overpriced

You don’t get very much information and is not at all what I expected. A quick Google search could easily replace this app. The extras that seem like they’re included, cost more money, so you’re essentially only getting the first page of information and a diary to keep up with your own experiences. Definitely overpriced and not at all helpful. Hands down the biggest waste of money I’ve spent on an app.

- Wish I read the reviews

Can’t believe I paid for this app. I got it because friend recommended it but I see absolutely no use in it.

- Misleading info - DOES NOT COME WITH EBOOK

The description and pictures for this app are very misleading. It says extras and lists the ebook, white noise, classical music, etc. the picture shows these in the more section of the app but neither state that it costs an addition $12.99 for 6 months. You don’t find this out until you purchase the app for $3.99. This is false information in the description and needs to be changed. I would not have purchased this app had I not known the ebook was an additional cost. Don’t fall for the same trap I did.

- Junk App

Literally provides zero informative info. Don’t waste your money.

- 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.

- Not worth it

You pay for the app and then have to pay for additional subscriptions. The app is hard to navigate and doesn’t have much information. The tracking system is not useful

- Useless

Not helpful, seems to be repeating the same exact information over and over.. There’s plenty of free apps that can give you this information and more. Don’t buy.

- So Helpful!

I loved this app! It was spot on for her “rainy/sunny” days, and really helped me understand what was going on with her development and what to expect! Highly recommend to use!

- Not worth paying for

I think this is just a waste of money. I can get all of this information on google and there are better free apps to track actual milestones.

- Unhappy with customer service

I recently purchased the app and was pleased with how easy it was to get the information I needed about growth spurts my baby was going through. However, I was very confused about the cost since I thought the “extras” offered savings in app cost per month ( I thought I had to pay a monthly fee) so I contacted them through the web page and 3 days later I still have not heard from them about getting a refund.

- Sorry, I can’t read Japanese.

Went to check my app and everything is literally written in Japanese and I have no clue how to change it back. 🙄 Waste of money.

- Not great

The app layout is confusing as it’s not intuitive how to find info. It also tells me contradicting info - one page says the next leap will start at 14.5 weeks, and an other day around 19weeks. It also tells me we’re about 25 days from the end of this leap...? I’m sure the info is evidence based. It’s just not helpful.

- A MUST for parents with a new baby!

Anyone who doesn’t find this app helpful may be dense or just not wanting to learn or be patient with their tiny baby. This app, and the book it’s based on, are like a playbook for parenting course though the app stands alone well. The cost is Absolutely worth it And makes the tough times with our little one make more sense and feel more manageable.

- Not accurate

It is not a good app. It is never accurate for me and most of the leaps say the same thing with different twists.

- Disappointing, needs some changes

I’ve read the Wonder Weeks book and I’m a big fan of their research. I initially downloaded this app to track my baby’s sleep and follow along in her leaps, but I’m really disappointed by the format and what features it has to offer. Unless they make some changes I don’t think this app is worth paying for. Here’s are my two big issues: - The format for viewing sleep is very rudimentary. Once you input the times, the only way to view the data is a list of times, in the order that you input them. The only graph is a very small pink line, but it’s not clear if the pink line represents sleep or awake times and it’s very hard to read. I wish this included another way to view the data (like a better graph to show patterns). I want to know if my baby is starting to have a schedule or be able to look at her past sleep times and know if we’re getting close to a nap time. I can still do this, it just takes a lot of clicks and I’m just viewing raw data. In addition to this, it would be great to be able to put sleep and feeding times on the same graph. This would help me so much as I get ready to start my baby in daycare (so I can give them a rough schedule). - There are also very few features for what you pay for. Unless I’m missing something, it looks like the only thing it has to offer is showing you what week your baby is on, which I can do just by looking at the schedule. All of the features in “My Diary” shouldn’t spit out raw data (the exact thing I type in). It would be so much more helpful if in addition to “show all my inputs” there were options for how to view your data - like different kinds of graphs or charts. I would like to note that I really appreciate the privacy policy this app has. I reviewed the privacy policies of all of the major baby tracking apps and was disappointed that all of them included a clause to either indefinitely keep or sell the data you input. It seems like this still does that, but it was a lot more clear on what your data is being used for, what’s kept, and who they sell it to. If anyone from the app is reading this - thanks for the transparency!

- Total waste of money, feels like a scam

Not worth your time or money. I have a bunch of free apps that have 1000x better and more accurate information. Really disappointed and wish I could get my money back. Even just reading some of the text, it feels like fluff and so repetitive. Anything else would be more helpful.

- Fascinating tool for understanding baby

Have used with both children. Very astute insights, great for better understanding baby and knowing how best to support them. Great navigation and easy to use app

- A giant advertisement for the book

Unfortunately this app tends to be one big advertisement for the book. I am disappointed I spent money on an ad. They base their “leaps” off of normal child development milestones that are readily available for free many other places. Not to mention the leaps haven’t lined up for either of my children. Don’t waste your money. Go to the CDC website or just google it.

- Informative but difficult to navigate

No real main page or main menu, so you’re never sure where you really are. There’s a lot of information but it isn’t organized clearly at all.

- 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!

- Love!!!

We are in leap 3 now and so far have totally loved this app! It’s been very helpful in knowing what’s coming up, and how to help baby through these transitions!

- Don’t waste your money

I am so upset this app is so bad. When I email support I get no response either. The app tells me baby is entering a new leap in one day but the chart tells me it’s not for another 4 weeks. Very little useful info.

- Ok

This wasn’t really helpful. I could just google and find out more for free than what this app offers. If you want to keep notes about baby in one place I guess it’s good for that.

- Useful

Helps you to empathize with what your baby is experiencing. During the smooth transitions leap it was true my baby enjoyed watching smooth motions and flying her around like an airplane made her happy. It’s interesting information, stuff I learned and forgot in my childhood development class, and does it’s best to be as accurate on timing as possible.

- Inconsistent yet repetitive

This app makes no chronological sense. On one page it will say your leap ends in 5 days. But you read the description below it and it says you’re waiting on the next leap. There’s no info for a current one. Then later it says the next leap starts in 9 days. But another page says the next leap doesn’t start until 26 weeks, yet the home page says it’s 22.5. It’s all over the place. And doesn’t matter. Because every leap is the exact same. Baby gets fussier. That’s it. Okay. But my baby is fussy like this all the time, or at least there’s no predictable ebb and flow that follows this kind of “calendar.” If you want to learn milestones, download the CDC app. Or google it. This app provides nothing of value.

- Great information to have on hand

Love that this points out the silver lining of our little boy’s stormy periods. It’s cool to read about his developments and see them happen before our very eyes!

- Useless, filled with bugs and typos

Not great or helpful.

- Mom of 4

This child is now 8 months old and I used the wonder weeks app with him. It was spot on with sudden behavior changes with my son and explaining why he is acting different and that he’s not just having a tantrum. He is now a happy bubbly baby and even though he can’t talk yet, we know what he needs better.

- Waste of money

Waste of money. You can read all this online for free. I purchased because I was curious about the WiFi baby monitor but that is another $12.99. I wish I could have my money back.

- This app is dumb

This app is awful, junky, expensive and absolutely not helpful.

- Super underwhelming

I got this app based off a few people telling me how useful it was. I am unfortunately super disappointed. The leaps are extremely INACCURATE. It never aligns to how my daughters behavior is. It always seems like it’s a few weeks off and yes I did her actual due date not the day she was born. The information for the leaps give you little detail. They only explain so much which for a new mom you want as much helpful information as possible and this just leaves you with more questions. I wish they had more helpful games and things you can do with your baby to help them grow developmentally. Overall I think it’s a waste of money, wish I could get a refund. It really doesn’t help with much.

- Complete waste of money

Wished I had never spent the money on this app. Not helpful even in the slightest and it’s a terrible looking app...

- Difficult to navigate the app.

The idea of this app was pretty exciting so I paid for it but I didn’t find it as helpful as I would have liked. It’s not personalized to my sons growth, and the worst part is that it’s difficult to navigate. I’ve tried to understand the hype but I don’t get it.

- 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!

- Terrible Interface

The info in this app is ok. But the horrible interface makes it basically unusable for me. I’d urge you not to waste money on this. Wish I could get a refund. Just buy a book.

- Confusing and not intuitive

While the information is very interesting, the app itself is confusing and not very helpful. I feel I’d do better just reading information about development on a website. Perhaps I need to purchase the additional upgrades to make it worthwhile, but with the base purchase feeling like a waste that’s not going to happen.

- Poorly made, difficult to understand

I put in my sons birthday and it didn’t even display his age correctly. Extremely buggy and poorly designed. Save your money.

- It’s a wonderful app

My husband and I love this app! We highly recommend it!

- app is terrible - 0 stars

basically useless information in an old school format. not worth a penny. i would give it 1 star if it was free.

- Great app

This app has been amazing! It is exactly on track for my little guy. Things start to get a little crazy, I check the app and get an explanation of what’s happening in his development and that helps me cope with what he’s going through.

- Good app - hard to navigate

I like the information provided but i can’t help but feel i am always missing something, i’m at leap 3 and just discovered a section with games in “my diary” - i like the app but wish it was more user friendly

- 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...

- Awesome

I honestly the best app ever ... like it’s sooooo spot on it’s creepy 😂!!!! It’s worth paying.

- Worth your money!

Helped me understand my baby so much! Especially in those first couple of months!

- Awesome

One of the best baby tracker apps out there!! Have used three on the babies. Love

- Book is not included with purchase cost

Good app, but was not clear to me that I wouldn’t Get a copy of the audio/e book upon purchase. This is considered an “extra” that you have to pay for. Wouldn’t have purchased the app if I knew this ahead of time. Disappointed.

- Content removed and dwindled over time

I purchased this app for my first child nearly 1.5 years ago. The available content has dwindled over time and they have removed items and made it more difficult to navigate and find info. This wouldn’t be an issue if the app was free, but I want access to leap information beyond 10 leaps like I did prior! I paid for that and can no longer reference the information. Feels like a scam to swindle more money out of you!

- Paid for months ago... pay more again?

In the new update of this app, “minor improvements” actually means the whole app was changed with an added “gold” subscription feature. I paid for this app about 7 months ago and feel bothered that I paid for access to information I now have to pay further more (ie milestones). I understand a pay wall for audio and book features but I feel cheated. New customers should ignore the comments about getting more information on the app as you DEFINITELY do not.

- New update is a rip off

I paid for the app when my son was born. This week the app was updated and now requires all current users to pay more money to access certain features. My son is eight months old and half way through his leaps. This is ridiculous.

- No longer get everything you paid for

They make you pay for the app and then updated to lock a lot of info to make you upgrade to reveal it. I used to recommend this app and mainly use it for the milestone lists - will no longer recommend, that’s for sure. We paid for the app, they shouldn’t take away the information we already paid for... if you were adding something new, that would make sense to call it an upgrade and give the option.

- Bait and switch

We paid for the apps and now they added an update with features but locked them behind a paywall and they want you to pay for a monthly subscription. I understand that kind of thing when its a free apps but this was not free and we paid for it. We should be entitled to new feature when the apps get updated. Feel like a bait and switch to me and I won’t recommend the apps to peoples anymore.

- Not needed

There is definitely some really good information however the app is equivalent to buying a baby book... it is in no way required and won’t help with the baby. It’s basically just an explanation of how the baby’s mind develops from week to week.

- Love it!

Such a good app. Even if you’re not submitting for analysis. It’s so on point work wake windows. Really helped us

- Not that good

I was looking for an app that would help me develop my baby’s skills, this app only talks about leaps, it’s helpful in finding out what your child should be doing at what leap but no exercises or ways to promote development. I would recommend BabySparks I paid more money for it but it gives me day to day exercises to do with the baby.

- Love this app

Explains so many mystifying behaviours!

- So helpful

I’ve found this app to be right on every time give or take a week just like it says. My daughter doesn’t get really fussy but she loves to be with me a lot during her leaps and her sleeping/eating is off. Right after the leap is over everything always go back to normal. She’s at the stage 29/30 weeks when she just realized that I can walk away and still exist and she’s actually cried a couple times. It’s crazy how accurate it is to me. I love this app.

- Voir le monde avec les yeux de mon bébé

Je suis fascinée de suivre l’évolution de mon bébé, chacun des bons correspond tout à fait à des changements qu’on observe chez elle. Cette app m’aide à comprendre ce qui se passe dans son monde!

- Amazing app

The app is on point with all my daughters changes! It helps a lot having some knowledge and a guide regarding what she’s going through! I highly recommend this app!

- Not worth the money at all

You can get all the info here and more on YouTube or any baby page. Not worth the money. This app doesn’t really do much. Far too simple. I don’t understand the hype about this app. Waste of money really.

- How does this work?

My baby is 14 weeks and was born on her due date. The app says that she is entering Leap 4 now but the details about Leap 4 state that she’ll enter Leap 4 at 19 weeks from her due date. Is this an error in the app or am I miss-understanding something? I tried sending this via the app support but it wouldn’t/couldn’t submit it due to the “email configuration” on my phone. 🤷🏻‍♀️

- 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!

- Simply AMAZING!

What an excellent app! I have the book and the audiobook but I also LOVE the app cause it allows me to read on the bus, when someone is driving me, during lunch breaks and whatnot.. It is a must have for any new parent (especially first timers like myself)!

- Love it

This app really helps you understand what’s going on in your child’s development and why their moods have changed or why they are extra fussy

- Amazing!

The wonder weeks has been instrumental in understanding our babies, this resource is just so thorough and just so helpful. Having read the book and used the app has helped me to be more patient, understanding Mama and it has given my little family a window into understanding our babies in a way that has changed our ability to relate and be supportive to the things they were experiencing in such a unique and wonderful way. I’m so impressed with the work done to create the wonder weeks this to me is the most valuable resource I could have been given as a parent. I am very thankful for this!

- Really informative and helpful

As new parents, we found this app invaluable when trying to find our way and understand what our baby is going through. Great value and used frequently !

- Needs a little tweaking.

This app would be great except for the sleep sounds. Perhaps with the next update the sounds on the continuous loop wouldn't have a break in them. It's distracting when the sounds are so short and you're trying to put your baby to sleep.

- Highly recommend for first-time parents!!

Having a ‘difficult’ baby can be extremely stressful and having this app truly eased my mind knowing that there was a reason for each behaviour I was noticing (excessive crying, changes in sleep pattern, etc).

- The best

The best

- Most useful app in babies first year

I have used this app for both my boys and it has been such a lifesaver! To know why my typical happy boys are all a sudden not sleeping or nursing all the time or especially clingy has been so helpful to have grace and patience for them as they go through these leaps. I recommend this app to all new mommas I meet!!!!

- Best thing ever

I’ve used it with all my kids and recommend it to any new parent that wants to understand the fussy stages more and wants to have a heads up of when they’ll happen

- Not what I thought

I had heard great things about this app. So I decided to download it and check it out for myself. l find it wayyyyyy off for my daughter and that only makes me panic something it wrong. I’m constantly asking my paediatrician questions because of what Wonder Weeks is telling me my child should be doing. Not worth the 4$. I will say the set up is nice and it’s easy to navigate but that’s the only positive thing I can comment on.

- So helpful

Been great for understanding what’s been going on with my baby!

- Wonder no longer

This app is so worth the money cheaper than the book. It has been so helpful to me as a new mommy. learning my baby’s growth, development cycles, how she is affected, what things to do to in courage her to growth is wonderful. It also helps you see when they might be extra cranky, cling and crying for what seems like no reason. growth is always taxing even on an adult.

- Helpful App

This is a good App for understanding what you’re baby is experiencing in developmental weeks and can help you to be a little more patient and thoughtful. I’ve found that not always do the dates coincide with what my baby is experiencing and sometimes my baby is a week or so ahead/behind but as a rough guide it is excellent. There is so much that our baby’s go through in the first year of life and this is an excellent resource tool to understanding that just a little bit more.

- Second time user.

Used with my first daughter and it was fairly accurate. I enjoyed the suggestions and felt more confident about why and what was happening and what to do.

- Great app

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

- Fantastic App

I wish I had downloaded this app sooner. Started using it for my 10 month old and it has helped us learn so much about his developmental stages and his good days and bad. I recommend this app to anyone who has a little one

- Must have!

Love it! So comforting to have this guide. It’s so nice during more fussy periods when the leaps are the explanation!

- Wonderful Wonder Weeks!

Great to be able to understand what our little one is learning and developing at certain times. The first year is so exciting, but it is also a time of so much change so any insights are helpful.

- Very informative

I love the app I just wish that it had the same ability checklist that the book does. It would make the app more interactive.

- Amazing!!

Get this seriously, get this app!! It explains sooo much of your infants behaviour.

- Name Change

You cannot edit your profile or change your name

- Not enough

I’ve never paid much for an app...but I figured this one would be worth the buy, however ended up disappointed. I like the concept of the wonder weeks, and it seems to be accurate with my baby’s behaviour and development so I appreciate the information. The app however is far too simple for a paid app, and not much more information than I already found online for free. The app recommends buying and reading the book which I didn’t expect after purchasing the app. There’s also no interaction such as a log to record your own baby’s development in a check list kind of way, or questions to determine whether they’ve past a certain leap, record mood, or sleep pattern, etc. The app could be so much better, not impressed.

- So far so

Just downloaded it today. Easy to use, great ui, very helpful info so far.

- Great app but...

Great App but I always accidentally click on the videos while I scroll down the page, it drives me nuts!

- Love this app!!

Great app that helps you recognize how your baby is developing and what new things they are learning. Excellent for understanding when a baby might be fussy as well.

- So helpful!

I’ve had this app for both my babies and it been so helpful to keep me focused on what is really happening with baby and how I can help her. It helps knowing whats going on with her, so that I’m not so stressed and in turn I’m able to be more patient and present for her.

- Pretty accurate

For us it’s pretty spot on. When it says there’s going to be a leap, he usually goes through the leap!

- Very helpful

This app is very helpful in deciphering what was up setting my son at night. Two days after downloading the app my son had a very terrible sleep and when I consulted the chart it was to the day accurate for the worst part of the leap he was experiencing. The information has been very helpful as well as informative. I would highly suggest this app for any parent raising a little one.

- Easy, Informative, Fun!

This app is great! I love following along and seeing where our little one is at every day/week. Lots of great information to read about and the app has answered a lot of my questions about what our little one is experiencing in her world week by week! Thanks Wonder Weeks 😊

- Amazing info!

This was baby number 2 for me and this app helped me so much. I was so much more calm and collected when baby was going through a fussy period because I knew why ! And I had help for what to do!! Made me feel so much more in control even tho having a baby is so unpredictable or used to feel like it ! Thank you wonder weeks!! Recommend to everyone!

- Plain

The app is very boring and really only talks about leaps. Doesn’t give you activities to do at each age. Just wish it had more to it for the cost. Another thing that drives me crazy is it only works vertically and not horizontally.

- Incredible!

We can’t wait to use this app with our second baby coming soon. It was bang on with our first and saved my mentality on more than one occasion! Seriously so so good! Best $5 ever spent.

- My most favourite app!

I wish I could rate this app more than 5 stars!! I have loved it every second since the day I found it! As a first time mom, I had no clue what to do with my tiny newborn! Sometimes she would cry and I would have no idea why she was so fussy. Yes, maybe sometimes it was a sore tummy, but this app is so amazing at mapping out my baby’s fussy periods and letting me know how I can help her through them! I love reading about the leaps she is going through and reading about how I can help her development when she is going through them. My little one is almost done with her last leap and I will miss this app so so very much!!

- Baby must have

Can’t believe how helpful this app has been. Just as I am at a breaking point, I take a look and there’s a storm cloud. It makes me better understand her highs and lows and I love the book that goes with it. Super informative.

- Great

Really useful information and helped me better understand what was going on with my little ones.

- Informative

The activities it suggests to do with your baby are helpful and I do like reading about the developmental leaps he will (at his own time) go through. Side note: the way the dates portion of the app is presented is dysfunctional. Why not have it in calendar format? The entire brick format doesn’t make sense.

- Misleading advert for a good app

The reason for the low score is that the advert lists many extras like access to the ebook and audiobook. Once you pay for the app however you are informed that all of that is behind a monthly subscription and the initial payment only covers the barebones app. The app is good and the information is really useful. I just think the marketing is quite underhand.

- The old app was so much better

I used the old app when I had my daughter 4 years ago and loved how user friendly it was. I had also purchased the book. So when I had my son earlier this year I downloaded the app again but this new app is awful. It’s so confusing. Bring back the old app.

- Not suitable for me, how do I receive a refund?

I felt this would be suitable for somebody who was tracking breastfeeding and liked to keep a diary of content of baby’s development - this is misleading as you need a subscription to be able to access those types of things

- Don’t understand the fuss?

The app based the leaps on due date, when due dates are really guess dates. The grammar is poor - on the first page it refers to your baby as “you” after initially referring to you (the reader) as “you”, which makes no sense?! The opening paragraphs in the “this week” tab seem to be pretty much repeated in the next section and so just seems pointless. In one leap it says baby can “see as clearly and as far as you”, then shows a video that seems to suggest baby can only see up to 75cm?! Just general discrepancies between info Rather disappointed I’m the app considering the cost.

- Extras costs!

Bit unhappy. I saw the app, read about it and looked great. I saw under extras that you get the book. I was mislead as I believed you got the extras. You need to make it clearer this costs money. As I wouldn’t of paid for the app. I wonder, can I get a refund now?

- Not what I thought

Not worth buying, don’t find it that useful. Wanted something to explain what was happening with babies development week by week. This just explains certain leaps or milestones, not very useful

- Love it

It really works,used it for all my kids

- Crashes constantly

Heard good things about this app and was happy to pay for it, but it crashes every time I try to open it. Terrible.

- It’s ok

It’s an ok app, bit annoyed I paid for it when I probably could find all the info online. I thought I’d give it a go as the ‘extras’ part intrigued me. But you have to pay a subscription to get access to them, which isn’t clear, despite them saying on another review from March they were going to look in to editing it! If I could go back I wouldn’t buy this app.

- Worst app ever

The most difficult app To navigate that I have!!! Why is it so difficult to read the leap diary? What’s the point in having it if I can’t figure what on earth it means??? I entered my babies birthday instead of the due date so all my dates are wrong anyway and I don’t know how on earth you change it... no buttons in settings to alter. Totally pointless me having this app! Also, some of the information is repeated during each leap so basically... every couple of weeks, your baby gets a little fussier and then better. That’s all you need to know no point in getting the app!!!

- Rubbish

I just don’t understand all these positive reviews. My child has not followed any of the suggestions of the leap schedule. This app proved totally useless for us. Money wasted.

- Good app

It’ll be amazing if it would be possible to add when the baby starts his leap. My baby started leap few days earlier and I wanted my leap chart to be updated. Anyway it’s a good, reassuring and useful app, especially for first time moms.

- Wish I hadn’t bought it.

Vague and unhelpful information. Hard to navigate app. Generally really disappointed in this app, as others have raved about it. I find a baby book to be much more informative. Regret paying for it to be honest.

- Compliments the book

A good app that compliments the brilliant book that is The Wonder Weeks. The app is just the tip of the iceberg in terms of information / content, but a useful tool to remind you when to pull out the book and understand why your baby is cranky!

- A bit complicated for my liking

This app is a bit confusing and hard to navigate around.

- Not worth the money

After lots of rave reviews, I can’t quite believe I downloaded the correct app; it is so hard to navigate, badly written and incomprehensible. What do the weather symbols even signify? Why is white noise not included? Editing my notes is difficult, the English is poor, swiping between pages is confusing, the calendar is hard to read. As a new mum in need of support, I could have done with an app to make life easier rather than a time wasting rip off. Don’t bother.

- Disappointed

This was app was recommend and I’ve barely used it , its not pleasant to navigate it’s just a load a text with a video here and there and its an over complicated read . It’s just plain boring .There are far better free apps and resources online which explain development in a straight forward more enticing manner .

- Dissapointed

After seeing so many recommendations for this app I really don’t see what all the fuss is about. I don’t think it offers much more information than most free apps. Can’t believe you have to pay for this! How can I get my money back?

- Think it’s not working properly

At the moment I’m underwhelmed... Should something appear when you click the 'More' jigsaw pieces on the main screen? I can't seem to figure out how to add a milestone and wonder if it's in here... as the button does nothing when pressed? I think something isn’t quite right, as I can’t scroll on the ‘about wonderweeks’ info either.

- Love this app

I used this app to guide and reassure me if my baby was being fussy it gave me the reassurance we we’re going through a period of development. I also used the notes section to keep track of milestones.

- Old fashioned interface and hard to use

Heard quite a bit about this app from my fellow NCT Mums and downloaded it. Had to double check it was the correct app because even the screen grabs of it in the App Store show it to look really dated and old fashioned in terms of design. I purchased it nevertheless and have to say that unfortunately I am not impressed. It’s really difficult to navigate and for something that should be really simple and intuitive (ie a calendar feature that then links through to information about what your baby should be experiencing at that time plus data on how long it is til the next leap) it just didn’t deliver on this. Also the content itself is not written very well (whose decision was it to write it in the baby’s first person rather than he/she’ ?! It’s not as if the baby would be reading this!) The calendar feature isn’t clickable and doesn’t tell you what the icons mean or click through to the corresponding info page. I can’t really see how this app is very useful to be honest and in an age with some many brilliantly designed and well-tested apps I think this needs a completely redesign and a lot of user feedback taken into consideration. Take heed app designers.....

- Great but something missing...

It’s a clear layout and seems good so far (only just started using it). However there is one problem that is when you want to write a specific entry eg in milestone, there’s no way to add an entry! So to me a large part of the app is unusable.

- Poor not worth the money.

Quite difficult to use, the nap times option is not straight forward to use (like a timer for example) so all you do is record times - all the time - Huckleberry app so much better for that. No option to record feeds, no option to record nappy changes, no option for pumping, medicine, weight etc.... would add so much to the app. Also the basic version only gives you limited info. I’d try to get the book instead of the app, not worth spending £4 for sure!

- Should be free

I don’t understand what I’m paying for, detail is minimal for each leap - it’s useful but not enough to warrant paying for the app

- Really handy app

Rate this app as it’s spot on with my Sons fussy periods. Gives tips and advice which is handy too

- Not accurate, activity ideas not straightforward to access

Says to find activities in the diary section.. but all there is in the diary section are my own notes. Also not accurate for my child,- all the books talk about week 6 leap which is what he has (not week 5 as per the app).

- Misleading description - extra money needed for features

I bought the app based on the description but once I’d paid it appears the features listed are not included and need an ongoing subscription which is very miss leading The features offered are of no use to me as I have the book already . I can now see other people have complained Ed about this and it was supposed to be changed but it has not - beware

- Very basic

What you actually get with this app is very basic information that you can get for free from plenty of other apps and websites. Their con man description makes it seem like you get a lot more for the price but most of the features actually require an expensive monthly payment to access them. Complete rip off.

- Useful info but confusing to use!

This app could be really good, the info is invaluable and I’ve found the dates pretty spot on. However... it’s hard to tell that because the lay out is so confusing and the app is both telling me that we are in leap 5 and at the same time telling me it won’t start for another 75 days?! It did this for the previous leaps too. It’s so confusing and honestly quite annoying. A lot of the info is generic with each leap too which is disappointing.

- No white noise or music!

I already have the book and decided to get the app because the book said that there are scientifically proven white noise tracks and music on the app. But it turns out you have to pay a hefty monthly fee to get and maintain access to these. The app description simply lists these features as 'extras', with no indication that you have to pay a subscription for them. So I really don't need the app because it offers nothing more than the book (except a diary to fill in for sleep, milestones tracking etc which other apps are much better for due to better UI etc). It turns out that I have to buy the separate 'Wonder Weeks Sleep' app for the white noise and music library - but I've already bought this one and feel cheated to be honest! Especially since I already paid for the book. Developers, please be more transparent in your description and don't waste people's (aka sleep-deprived parents') time and money!

- Very bad!!!

Terrible waste of money ... cut and paste information poorly written. Confusing in every way. Awkward to use.

- Do not buy! Incorrect milestones; No second child option

According to the app, 6-9 month milestone - Asks their mother or father to sing a song; Plays a pick-a-boo with a younger baby; This is just ridiculous! You cannot add a second child should you wish to use an app. Non existing support.

- Good app

Good app but tbh not worth the price it’s really expensive for what it is !

- Really helpful

This app condenses a lot of information that you’d have to spend a long time reading and researching into a very user friendly space. Invaluable for a busy parent. Thank you!

- Informative but poorly designed

This app is just extremely poorly constructed compared to others. Not a fan of the layout and looks quite old in terms of designing. On the main page at the bottom it says “you do this” and “you do that” but its talking about your baby and not yourself, almost like a child wrote it. Also when your hovering over the leaps page, it shows where your child is but does not say what leap it is and wont let you click on the leaps to bring it up. Also on the child activities it only has 1 thing to do! Honestly a waste of my money. All that I have read on this app I already have read online for free. Other reviews are fake. Rubbish app do not waste your money.

- Not much help

I thought this would help me much more in understanding the development of my baby in the 4th trimester and beyond but it hasn’t. In fact there is pretty little to learn. Disappointed to have paid for this

- Do not get

Very poor layout and not easy to navigate around. After spending the money on this l, I really tried to make it work. It is repetitive and not succinct at all! Long, repeated blurbs (in multiple areas of the app) that don’t actually give you any clear information. I read the bad reviews before purchase but thought I’d give it a go, Wish i had taken notice of the awful reviews!! Waste of money and time On top of the already strep price, it is not the full app and wants you to buy more to unlock other features. Very money grabbing for very poor content. Also, it is only half the content as it needs you to purchase the audio book AS WELL for this app to make sense. I am disgusted

- Constant upsell

The app is pretty good, but it feels like a free app, with constant upsell to the book. It’s annoying to continually be told “even though you have paid; you have to pay more to get the insight”. I would recommend users to just buy the e-book instead of paying ££ for the app.

- Leaps!

Brill app. Let’s me know when my little ones leaps are, how long they will last and what they will learn after the leap. It’s been spot on throughout!

- Misleading description

I’m quite annoyed that it wasn’t made clear that the ‘extras’ would need to be paid for as a subscription. The reason I downloaded the app was that it included access to the book. If I had known it didn’t, I would have bought the book instead, however now I really don’t feel like giving them any more money!

- For the money it’s poorly laid out

I wouldn’t waste your money. Google has the answers and it’s free. Hard to use and poorly laid out. Don’t waste your money

- Original purchase doesn’t unlock all content

It’s a good app but despite having to pay for it you don’t then unlock all the content and have to pay for a subscription. Money grabbing if you ask me. Update- the unlocked contact is very minimal you have very generic descriptions to read and a good chunk of the app you cannot use unless you pay more money per month. Very ridiculous.

- Waste of money

Regret downloading this app. It’s hard to follow and hasn’t given me any extra insight into my baby’s ‘leaps’. I would give it no stars if I could but that’s not an option.

- New update is really awful!

This app has been amazing (it was once 5* in my opinion) until the most recent update. It’s now really hard to to use, the calendar no longer works well, to the point I have been thinking my son was in a different leap to what he actually was. It’s just no longer user friendly and it’s a chore to figure it out. Waiting for a new update & hoping this reverts back to the great user friendly app it was when I originally started using it last year.

- Since it updated they want more money!

Paid £5 for this app and since the update I can’t get any useful information without paying more or buying the book. I think it’s really unfair to suddenly cut the content during an update for people who have already paid for the content when buying the app! Wish I’d never bothered now, you’d never get away with this in the real world, yet people who run apps are able to literally rob you blind! 😡

- Confusing, repetitive, difficult to follow

The information is interesting and useful to know, however whoever developed this app needs to start again, with a simple layout which makes sense. I cannot get my head around where to find current information for my baby. Such a strangely laid out app. Please update it and change to a simple layout which defaults depending on my babies age. Interesting to read then responses to reviews by Marco - ignoring the feedback and simply justifying what you’ve done vs taking in feedback to influence product design.

- Poorly written and lazy examples of games and ideas

As I have used the app the general idea that babies go through ‘leaps’ in brain development has been helpful for managing phrases of crankiness and change. However, I can’t take the advice seriously as it is so poorly written and the examples feel as if they have been thought up on the spot by someone who has zero consideration about the developmental age of the child (irony noted). The app is supposed be backed by research, but I really can’t accept that there has been any in depth consideration in many of the suggestions and examples of games. Here are a few bits that have most bothered me, although there are many more: Poor grammar: The app flicks between pronouns on each of the pages- using ‘I’ to describe the baby then ‘he’ or ‘your baby’ in other pages. Seriously, has it been through an editor? This is very basic grammar! Lazy examples: Some of things suggested as games are a more than a bit ridiculous and actually any parent would know that they are not age appropriate. Here are some for leap 5 at 6 months- -untying shoelaces - as of you'd let your baby play with your shoes- the dirtiest things in the house. You’d have to pass your shoes to your baby to play with. -open and close cupboard doors- he can’t crawl or sit up fully on his own. How is he going to get to a cupboard door unless I purposely stand next one and hold him there? - empying cupboards- same issue. There’s no way he's going to empty any cupboards. What parent would play this as a safe and fun game? -show him abstract painting of cows. Are you seriuosly suggesting finding an abstract painting of a cow as if its an every day image? These examples annoy me so much I felt compelled to write a review.

- Useful guide to your baby

As a new mum this app really helps spot and track development and there are loads of extras (like a sleep tracker) that can help when you’ve no idea what day it is and if you’ll ever wash your hair again!

- Confusing & Hard to use

I find this app really hard to navigate! Everything is hidden away in 20 different places. It gave me no new information for over 30 days. At this point I haven’t been able to use the app for over 2 weeks because it’s been the same information and I read it when it came up originally. I even got in touch with the developers because I thought it was broken. Would have minded so much if it was free but for 4 quid, bounty is a much better and free app that gives you little bits of information every day. As well as the book my baby week by week which was for more helpful!

- Really useful for new parents

This app in combination with the book is an amazing tool to understand and help your baby move forward. It explains so much of baby’s behaviour and helps parents not to feel frustrated but show compassion and help their babies learn new skills.

- Love it

This app is so accurate and informative. Absolute must have especially for new parents

- 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.

- Worth every cent

Great layout, easy to use. Has a ton of developmental information and perfectly describes the signs to look out for.

- 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.


I absolutely love this app, really opens my eyes and helps me notice the developmental skills and leaps that my child is going through and experiencing !!

- 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!

- Update

Where is the update? Like the content but want the updated version - how do I get it ?

- Planning

I love seeing what is coming up for bubs and knowing if he is a bit more whingey there is a reason and it is normal.

- 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.

- Peace of mind

This app has been a very big help in the early days with my first baby.

- Great useful app

Helps me make sense of what my baby is going through & what is coming up! Very insightful & a great read.

- Great App!!

Used this app for my first and it wasn’t till he was 3 months age, now using it with my second just has everything and easy then carrying the book around to.

- Love this app!

I love this app so much already and I only downloaded it today. The ability to make notes is helpful, I just wish that I was able to share this information with my partner and visa versa with his notes on the baby.

- 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.

- 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!

- 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!

- 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.

- 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

- Dumbest app ever

I don’t know why I still check this app. It’s currently telling me my one year old should be helping with the dishes. Hahahahaha. Pretty sure whoever wrote this has never actually met a baby.

- Absolutely Fantastic

The app was easy to navigate, information is clearly communicated and laid out. App always worked! Such a helpful and invaluable parenting resource. Definitely 5 stars!

- Wondering what’s happening with baby?

This app gives really good insight into what is happening with your Bub and what skills they are developing.

- on point

Every time my baby is upset I read the leaps on this app and it help me help my baby through her storm clouds... also help me teach her new things

- 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.

- FTM says Thanks!

When things seem to be going tough, this app shows that bub is going through a leap and sunnier times are ahead! Thanks so much! Its helped me get through!

- Helpful

Great app to help with understanding the developmental stages for our baby. It’s been a great guidance tool in understanding what to expect.

- Sanity saver

Knowing what’s happening is a sanity saver, the tips helped to much too.

- Biggest parent helper

This app is fantastic. It has so much insight for parents with babies. I have watched this app for two children and it is spot on. It helps me develop my children’s learning and be relevant for them. I parent better because of it. Thanks for doing the research.

- 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 😳

- Not worth it

App not very user friendly, weeks didn’t correspond with my daughters behavior. Some good information but not enough to avoid me deleting the app.

- Better apps out there

A little disappointed with this app. Definitely not worth the cost. Much better cheaper apps out there

- Ideal for parents

Absolutely amazing especially as a first time Mum, not knowing what to expect... helps me understand my little babe so much more! Highly highly recommend

- 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.

- 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.

- So good!

I love to see the next leap and what development my bubba might be in for.

- I dont see any good thing about this

Its an ok app but should be free for what it is theres not much in it and the videos doesnt play. only one video played the first one about the change of her voice the rest of the videos ate black. not playing.. disappointed about this app

- Spot on

Love this app so much, it has helped me and my husband gain a greater understanding of our son’s mental development and all the changes he his experiences. This app is making it easier for us to support him through his leaps Thankyou.

- Very Helpful

Although all babies are different, this app is very helpful to understand the development process babies go through at different ages

- Not worth it

I don’t think this app is worth the money, it doesn’t really tell me anything useful it’s very fluffy and not detailed enough with specific leaps and milestones. It’s also not well designed.

- Useful to know what to expect; don’t take too literally

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

- So good!

This app has been such a great help with demystifying the scary unknowns of a developing baby.

- 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.


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.

- Awesome app!

Loving this easy to use app full of information! So great to be able to read week to week about the changes and neurological growth of my baby! Thanks!

- Must have

This app has been awesome. It’s a great way to understand and learn about your child’s development. Nice simple interface and great activities. Wonderful!

- Waste of money

This was the biggest waste of money as you can get all the info it gives you on the internet.

- 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.

- Don’t like this app

This app hasn’t been accurate at all when it comes to my little one. When it’s stormy my little one is great and when it’s fine he is a terror and I go by my due date not his birth date as well. I find the what to expect pregnancy app so much better.

- Not use friendly

I can’t delete a name that I made a mistake with And when I go to notes it crashes on me

- Very repetitive app

Dont bother it’s vague, repetitive, boring, they go on to say your child may or may not do these things listed. Not accurate to due date. I don’t see any point in getting this app. They are just trying to cash in on a first time mother’s worrying nature.

- Poor advice for mums.

Sets up a bad expectation that your baby should be going through developmental stages exactly when the app dictates. Language is poorly chosen. ‘Your baby now does blah’, when not all babies may see the same development.
