I was looking into Guitar Lab's reviews and most beginner's like me complained how the app was not too suited for them. The app was assuming that the user knew how to play some what. Even the users with basic knowledge found it a bit too fast.

I want to know if there was any other guitar app that's intended to teach beginner's how to play...learn step by step type of thing....
