About this app

The world’s No. 1 baby app! Understand why your baby cries more at certain times, isn't himself or herself and... what you can do to help.

During our research, which began in 1971 with Jane Goodall and the chimpanzees in Tanzania, we discovered that babies are more prone to cry and to be clingy or cranky from time to time. This behavior was shown to be related to a leap in the baby's mental development. More specifically, babies go through 10 mental leaps in the first 20 months of their life. A leap may be tough, but it's a positive thing: it gives your baby the opportunity to learn something new.

Use The Wonder Weeks app to:
- See when a leap starts and ends thanks to a personalized leap schedule
- Be automatically notified when a leap is about to start
- Learn to recognize the leaps based on the various signals your baby gives
- Discover the new skills your baby develops with each leap
- Stimulate your baby's new skills with 77 playtime games
- Keep track of your baby's development in your personal diary
- Link the app to your partner's app to keep track of your baby's developments together
- Share your experiences and ask questions in the forum
- Watch fun and interesting videos about parenting
- Complete fun polls and find out what other parents think about certain topics


Our mission is to help parents gain confidence in the face of the greatest leap in life: having a baby. We take a candid look at parenting, shed light on all sides and are there for all parents. We can all help each other and learn from each other.

Millions of parents before you have already followed, supported and stimulated the 10 leaps in the mental development of their babies. It's not a coincidence that we have been one of the best-selling baby apps worldwide for many years!

it's not accurate... at all. could be useful for education about upcoming developmental milestones but babies are all different and it's not worth paying money for, in my opinion. i used it a few times and then haven't opened it for months.

Hi Evi, it's possible that your baby started a leap earlier, but that doesn't necessarily mean the next leap will start earlier. Please email us at support@thewonderweeks.com for more information about the duration and timing of leaps. We’re here to help!

The app doesn't help at all. Don't buy it. The information is not relevant at all and it has been debunked. Also, if you ask for refund, they simply say that you have to ask Google, which will probably deny the refund request. I had to appeal with Google support to get my refund. Anyway, don't buy it and save some hard earned money. Don't get into the trap of being an anxious parent. Everything will get better, you don't need this app.

Hi, we're sorry to hear the app didn't meet your expectations. As purchases are processed through Google Play, refund request must be submitted through Google's payment system. We always point customers to the correct process and are happy to help if there are any issues. If you still need assistance, please contact us at support@thewonderweeks.com

I had the app for my first child 7 years ago and it was a god send, was on the dot each time as if she was reading the app too! but my second is all over the place, complete second child syndrome! I feel like I've been ripped off paying the full price and not being able to get a refund because it's absolutely no help at all. I've also been unable to get the app to sync with my calendar, so I don't get any notifications of leaps coming and haven't had help when I tried to contact support. pish
