User reviews

Doesn’t follow your baby’s age

So disappointed in this. I paid for a year subscription and it does not follow my baby’s age so I can’t even follow along on my baby’s current age. I have emailed twice about it with no responses

Not worth it.

Not worth the hassle. You sign up and answer so many questions and have a membership plan that you have to buy in order to use the app.

Free App but Need Membership

This is a free app for you to enter your name, child’s name, and child’s birthday, just to be hit with a membership pay wall.

Great support

Thanks for your quick response to my review, have updated the app and re-logged in, the new version of the app is great and much improved from the first version. A very handy resource to have and great support from the developers 😊

I love Willo

Omg I am in love with this app thank you all

Response from developer

Thank you, its an early version but we are working day and night to make it the best tool for new parents. The next updates will make it even better. If you have any problems or suggestion please reach out via email at any time, we carefully look at all feedback positive or negative to improve the app for moms and new parents.
