Today I found the best app for children in Google Play... PlayTales! It is a brand of interactive stories with amazing illustrations and interactive pages. The application is utilized as a library, linked here: goo.gl/WC9TP You can also find the complete listing of stories available for free or purchase. However, they have created a sister account where you can find all of the stories for free: goo.gl/fm0jJ I hope you enjoy it! I love them!
