Store ratings include star-only taps from in-app prompts, which skew high. The peak and recent figures come only from people who wrote a review, which skews low. Compare each against itself: the drop is the signal, and a big gap between the two usually means heavy rating prompting is masking unhappy users.

Not free

★ · v12.3.19 · Oct 13, 2026

So disappointing that this app is not free.

No

★★ · v12.3.19 · Oct 12, 2026

It’s inaccurate and poorly organized even if it was guided by science

Scam

★ · v12.3.19 · Oct 11, 2026

It provides less information than a basic google search and yet charges $5 a month plus in app purchases.

Love this App, but the Customer Service…

★★ · v12.3.19 · Sep 29, 2026

First of all, I just want to say that the information in this app is a lifesaver! It has been so incredibly helpful for my three babies. I am so glad that my friend recommended this app. With that said, my experience with customer service staff has been awful. I’m not sure if it is just one person, or AI, or if the team is trying to translate from one language into another (which would be exhausting!). With that context, I have loved keeping a diary on the app for each of my children. I’ve printed books for my first 2 kiddos and it’s been an amazing way to record memories for them. However, SINCE JUNE, the app has not worked properly. I haven’t been able to save any entries since then. I have written over and over again, and either I’m ghosted for weeks or told that developers are working on it… for 3 months. As someone who works in customer service, the treatment I have received is appalling. I have done my best to keep up with the entries in my notes app, but it breaks my heart my daughter may not have the same diary her brothers have. When you are dealing with people’s memories, you should be more sensitive. If you use this app for only educational purposes, you’re golden. If you need this app for anything else, like trying to save anything… Godspeed 🫡

Interesting but not worth the price

★★ · v12.3.19 · Sep 22, 2026

This app has some interesting information but I do not think it is worth the cost. It is not intuitive to use and does not give a lot of clarity on the actual skills your baby is learning. Overall disappointed and way too expensive for what it offers.

Nice idea but not realistic

★ · v12.3.19 · Sep 11, 2026

I really want to love this app. But it’s just like a horoscope…the guidance each month could be read at any other moment in time and still apply. We stopped using after 6 weeks as we got no value from it.

Slow

★ · v12.3.19 · Aug 22, 2026

It’s been on loading since 2025 smh

Stuck in 2021

★ · v12.3.19 · Aug 17, 2026

Looks like this app hasn’t been updated or maintained much for years. The app has no dark mode so your eyes get blasted by white and yellow when you’re in a dark room.

Bugs

★ · v12.3.19 · Aug 17, 2026

It would be great but every time I click something, it unclicks it for me. I want to follow along but the app doesn’t allow me to.

It's not that accurate

★★ · v12.3.18 · Aug 11, 2026

Babies develop at different rates so the estimated range on this app isn't accurate for a lot of babies, including my baby. The information isn't all that useful. I made the purchase on a whim and wish I could get a return but I can't.

No way to cancel

★ · v12.3.18 · Aug 9, 2026

As a first time parent, i thought the app was great for a while, but i did not want to continue for the second year. Problem is it seems they made it near impossible to cancel. It doesnt show under my app store subscriptions and it will only show me as active in the app, and no billing info or way to change anything. Based on this, i would not recommend the app as it can be replaced by some basic internet searches about baby development

Years of diary entries lost!!

★ · v12.3.18 · Aug 6, 2026

Wonder weeks has a diary feature. I have been using it for YEARS. I have (had!!) years of entries. Lots of memories. They recently nudged me to “create an account” and this process deleted all the diary data! Support confirmed it’s gone. No way to get it back. So yeah, 1/5 stars.

Waste of money

★ · v12.3.18 · Aug 6, 2026

Not very helpful. Pretty much is just a generalization of information of what may or may not be relevant for your kiddo. I was hoping it would be more personalized.

No support for month 1??

★ · v12.3.17 · Aug 2, 2026

Huh?

Waste of money

★★ · v12.3.16 · Jul 15, 2026

You have to pay for a subscription in order to see what the app is really about. If it’s not what you’re looking then you’re out the subscription payment because they don’t do free trials or refunds.

Don’t waste your money

★★ · v12.3.16 · Jul 8, 2026

The app is overwhelming, throws a bunch of information that you have to slide through to see, isn’t accurate and makes you question everything just save yourself the nonsense and don’t get it

Save your money

★ · v12.3.16 · Jun 30, 2026

Not worth it Al all. Same info you can get for free and you have to pay before you can see anything.

The English version of the app is bad

★ · v12.3.15 · Jun 13, 2026

Explanations are not very understandable. No good examples and very weird phrases. (If the child is “naughty”, talkies about a one year old)

Use with Caution

★★ · v12.3.15 · Jun 10, 2026

This is not always accurate. All babies are completely different and develop at different times so don’t count on this being accurate timeframes. My daughter was about 2 weeks later than claimed and would not be in the fussy phase for as long as it claims. As a FTM, this honestly made me a little more anxious than anything.

I do not get the hype around this app

★ · v12.3.15 · Jun 9, 2026

I purchased this app based on a recommendation from my sister in law. I do not find it that helpful. Yeah it tells you when a “leap” is about to happen but that’s it. I do not get the app that much and why parents like It. I regret purchasing it and will not renew.

Worthless App

★ · v12.3.15 · Jun 4, 2026

Truly such a stupid app. It was recommended to me by a therapist so jokes on me for thinking they knew what they were talking about. Just use google when learning about your kids development instead of wasting money on this app thinking it’ll be accurate for your child. I didn’t find a single use for this app.

Difficult to Trust Without a Real Trial

★ · v12.3.15 · Jun 2, 2026

I genuinely don’t understand why I’m required to pay before I can even properly evaluate the app. A trial is usually what helps users determine whether the product actually provides enough value to justify a subscription. Requiring payment upfront creates unnecessary friction and makes the experience feel more like a commitment than an opportunity to explore the app. The app may very well be good, but without a meaningful free trial or at least limited access to core features, it’s difficult to build trust or confidence as a new user. Already deleted.

Do not buy this!!!!

★ · v12.3.15 · Jun 1, 2026

I bought the 2 year option. Downloaded the app to my phone and my wife’s phone. The app never worked on her phone and now after a couple of days the app is not working on my phone. I asked for tech support/refund some thing and all I got was oh well, new software.. so sad so bad… so I wasted money for an app that doesn’t work with no suppport. Great business model, moral standards, and all around upstanding company… not!!!

Glitched

★ · v12.3.15 · May 31, 2026

Just purchased this and literally can’t click on anything or navigate the app at all. Waiting to see if it’s just a temporary glitch, but if it persists I’m going to have to ask for my money back. I’ve heard so many good things about this app, which is the only reason I haven’t deleted it yet.

The app crash

★ · v12.3.14 · May 29, 2026

The app crashed right after I paid for it and now I can’t use it

The opportunity
