Excellent app for learning scales
One thing that could improve is that when playing the scales it recognizes a successful attempt forward but not in reverse which prevents users from getting through the rest of the mastery practice. Other than that - great app for piano players at any level of experience. The app really helps to memorize the keys in the major scales and (as long as you know the relative minor) it is a very useful tool as a reference for making music in any key!
