Good app for someone with alzheimers

I downloaded this app and shared it with my grandmother who has alzheimers. She enjoyed seeing the animals. The slide interface could be improved; the page turn arrows were of no use. It would be nice if the slide interface worked while ones thumbs are on the left and right side of the screen.

That toy where you pull a string and it makes an animal noise sounds better than this app. Maybe thats where the sounds were recorded from!
