Should be better – What Note Is This? Review

I'm disappointed that this app contains some glaring bugs right off the bat. It's initially confusing because you're directed to begin by an arrow that points to nothing on the screen. By pressing buttons on opposite side of screen can you actually begin the game. The notes begin to appear well enough but after about ten notes the game sporadically hangs and more than one note appears (If it's quizzing chords that early in the first quiz it should be clearer; but it's not--it's a glitch).
