Terrible I really wanted an app that could help me improve my sight reading skills. This seems to be the only app on the market that comes close to what I have in mind, so I give it props for that; it's just so poorly made. The musical notation is written in an uncomprehensible manner. The app's ability to accurately discern the beats you tap is virtually nonexistent. It's also stupid how it just takes you back to the menu screen if you mess up a certain amount of times. What is the point in that? Don't get it.
