It works, but shows ad banner – Amazing Drums Lite Review

Initially thought it did not work (gave it multiple attempts). My iPhonr was on silent mode, but app didn't alert me. A different drums app warned me and that's how I knew. So this is a good app, but would be nice if it recognized if your phone is on silent mode and displayed a message about it.
