User reviews

It's not that accurate

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

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!!

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.

Wonderful app

On point in its patterns for my child

Waste of money

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.
