Worse then awful

I got it to practice my note training and it was a waste of time. It doesnt have anything to do with the range of a voice, so yes some notes it plays are physically IMPOSSIBLE for a person to sing. Like a soprano one yeah cant hit a BASS note. Not gonna happen! It doesnt tell you if your flat or sharp so you dont know where to move with it. Overall awful application
