I really dont like simply piano. I said that I know the basics because I learned that in school and it still showed the basics. I tried skipping but it didnt work. Sorry but that gave it one less star. Then I had to eat do I put my phone away and IT DIDNT SAVE MY PROGRESS ON THAT BASIC! Anither thing is that my brother wanted anither profile to try it and it pjt hin exactly where I was. I also hate how it cost money. This app would be good if the ads made it hsound how it really is!
