Do not and I repeat DO NOT download Simply Piano. It is an absolute waste of money. I had downloaded it and my sister and I both had an account, and we played for about a year, and I thought we were doing pretty good. We'll my sister just started in-person lessons with a local teacher, and she knows more in 3 lessons than what I learned in a year of playing simply piano. Simply Piano misses teaching you some of the fundamentals of playing piano. Don't waste your money, it is not worth it at all.
