1. I'm using android 4.1It's to boring for my 2 year old there's no change in the activities and most of the things you have to buyI was trying to teach my sister shapes but the screen froze on us that's why I rate this app 1 out of 5 starsAbsolute rubbish.
2. Also some children with significant disabilities can use.Other languages than english are not working.
3. I tried arabic , indonesian and turkish non of them worked for me.
4. Easy for little ones to use with minimal help.
