There is many things wrong with this app. While I do appreciate the thought and attempt to teach trombone, it has many mistakes. The scales are inaccurate (i.e.: "D Major" when it is actually C major). This app does not teach trombone, but instead provides you with sheet music. Which is also kinda annoying, because it doesn't give you the option to listen to the music before playing it. 8Notes is a better option

Hi, thanks a lot for your feedback ✌️. We fixed the scales, thanks for the hint 😉! You are right, with tonestro you can't learn from scratch. You have to know basic things about music/the instrument. You get feedback on pitch & rhythm while playing, you can improve your skills & compete with others while having fun & staying motivated 🎵. Alex

Great app that makes me play those 20 minutes every day. New songs are added all the time, the app shows you what you do wrong and you can also compete with others in weekly challenges. Recently background music was added and that makes it even nicer. 5 starts deserved for a free app. (With advertising after playing for about 15 minutes on a day)
