User reviews

Scam annual rate

I was supposed to be paying for .67 cents until the first of the year then charged for yearly rate instead they took 34.99 from my account

Response from developer

Hi, apologies for the confusion, its not a scam, the .67 cent is a weekly displayed of the Anual payment. This is Apple’s way of displaying different plans. I understand your frustration, if you email help@meetwillo.app I can help you quickly get a refund of your purchase. The intention isn’t to confuse anyone, simply display as an example the weekly amount. Thank you for the feedback, we will make the necessary changes 🙏

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 😊
