User reviews

Forced account creation

This app was so helpful and insightful for understanding developmental changes in babies and toddlers. I have the WW book but it was nice to have the app too in order to see where my baby is at in terms of leaps.
Then they forced an update and now you can’t use it without an account.
I don’t want to create an account so that’s me with an app I can’t access . Why should I have to give my baby’s data for it to be sold ok no doubt?

Updated the $6 app to a paid subscription

I used to like the app. Paid $6 for the app and used it for my first kid and then my second. It forced me to install an update and now I have to have a paid subscription for something I used to have for free? Get out.

Deleting afte 5+ years

Asking for an account to be made years after using this app and not disclosing that now there’s a fee to use, is deceptive. It’s a shame, I used this app 5 years ago for my oldest, and now for my youngest who just turned one. What a bummer, instant delete the app.

Subscription Scam- Even after paying to download the app

DO NOT GET THIS APP! Unless you like to pay monthly to just learn what you can find out from your pediatrician. I purchased this app in 2024 to be able to access all the leaps for my first daughter. It was SO SUPER HELPFUL, I decided to use it again for my second daughter. Now even though I purchased the app, it’s making me buy a subscription since I have “2 children on there” even though my oldest has been aged out of the app for quite some time. I’m absolutely furious they wanted me to pay twice, and I refuse to do it. 0 stars if I could. So sad they became money hungry just like all of the others.

Changed to needing a subscription

I bought this app a couple years ago with my first kid and it was okay. I went back to it today and the app was asking me to make an account and subscribe $5 a month to access the information I already paid for years ago. I don’t recommend!
