Potatoss.com all of the games, you can find them in the AppStore. I made it with a friend a couple of months ago, it did like 250k downloads but anyway we couldn't fight against huge companies like disney or rovio, there is too many bad things happening under the hood of the AppStore. Specially what some companies call a burst... did you know that some Chinese companies who will download your games millions of time for money?
The apps were made with cocos2d and Chipmunk for the physics engine.
