I am new to the iPad. I am visually imparied. I had eye exercises on a p.c. But I do not have access to that pc any more. So does anyone know where I can get an app or program that has a ball that bounces on the screen. Also a ball in the center of the screen that changes size. It goes from very little to the size of the screen and then back to small. Back and forth like that. I would like any help, thanks.
