Customer Reviews

From Design to Customer Service...

This app is top notch! Beautifully designed, user-friendly (especially for the target age) w/impeccable customer assistance! (I had an issue resolved w/i minutes of emailing the company). Get this app! You AND your little will be glad you did!

Doesn't work at all!

I purchased this app but it not only doesn't work, it doesn't even open! Terrible! I'm disappointed as it was recommended.
