It looks like a very basic app, and it is. But my 4 month old daughter (now almost 3 years) loved it. All it does is display a picture on the screen along with copies of the picture, and the child touches each one, in whatever order she wants. A number appears on each one touched counting higher and higher until all the pictures have been touched, and a voice calls out the number along with it. To toddlers, or at least my daughter, it was addicting, and when she started pre-preschool, she was the only kid who knew her numbers up to 20 (not sure if it goes beyond that, but for a 3-4 month old, I think that's pretty decent).
