I wrote Connecto Shapes Free for my daughter, and it has been a great app for all of the parents I've heard from. It's a connect-a-line between two shapes game. It's for anyone who benefits from learning about shapes, patterns, matching, depth perception, and early motor skills. The default mode is to connect two shapes by tapping one and then the matching one. When two shapes are connected, a light tone is played, and when all the shapes on the screen are connected, a fun WIN sound is played. My youngest tester was 13 months old and she had a great time on this very playable, educational game. There's a free version that shows ads, but for 99 cents a parent-friendly ad-free version is available. Check out Connecto Colors, Letters, and Numbers too.
