This is probabely the best piano app I have used so far, it has got a great practice mode, clear instructions and a huge ammount of songs. The only downside I have about it is the price, for me, a student, it is a little bit too expensive in my opinion. All around, a great piano app when you want to learn how to play your favorite songs if you have a little bid of extra money lying around.
