Honest review

It’s not really accurate for my baby and the time frame they set for a “leap” is so broad that it kind of mixes with many intricacies and details. I think this app should still be free so to gather more information from real experiences with babies. Because at the end of the day every baby is so unique and at least mine has never really fit the mold for any of the advice out there. It’s nice to track other things like skills but honestly not so helpful for day to day stuff you actually WONDER about!

Free WW website was enough

Had higher expectations after the way it was described to me, don’t think it was worth the subscription cost. Personally will not be renewing after the 3 month period I purchased

Wasn’t worth it

Use the app twice. Dates for fussy phases and leaps were constantly out. Waste of money.

Getting me through motherhood

This app has really helped with my first baby. When he seems a bit fussy I have a look on the app & it explains what leap he is going through & how he may act… which has always been correct!

Amazing App but some issues commenting

The info in the app and book are insightful and huge help in figuring out how to help my son grow but having annoying time posting in the forum. Anytime I click the comment button my response bar disappears until I hit done. It’s very frustrating but other than that the app is incredible and make sure you read the book as well.
