My 4 year old and I spent over an hour on the app the first day - and I am quite happy so far! In todays iPhone world, this app is a throwback to "Reading Rainbow" and exactly what I was looking for for my son. He gets to feel like hes on the phone, but hes looking at a static pictures and reading or listening to stories. And by having to turn the pages himself, he feels like hes engaged and actually doing something. I think this is a great educational tool.
