Great learning app.
I have been using this for a couple months now, and has helped me quite a bit. I really like that it has almost any popular song you want and easy to control speed, replay, beginner or advanced(Im just at beginner, but nice to hear what pro sounds like to give inspiration)
I have a couple other piano apps as well, that give feedback, simply piano, which is great too, and Yousician, which I found expensive and moved too fast for my abilities. This one is my go to site when wanting to play. Highly recommended.
