istory apps (Interactive stories for kids)

My original idea was to create a kids story book, but taking a more modern approach to it, I thought why not make it an istory app. Basically its interactive stories for kids. Its funny I've never heard of istories until the other day when i seen my brother showing his son a little book, the istory book had a voice over to read out the story and it had animated page turns, and very cool sound effects. I thought what a great idea for kids. After class critique my lecture also touched on the point that I should look into istory apps, which has now lead me to this stage now of the process. Here are some of examples of how istory apps look like :

This example here shows you that you can slide through to different books
