Okay. So for whoever wanted to play an ocarina, don't buy this. I know I sound like a whiny baby right now but look, all that this app has is an ocarina that beeps instead of play, and there is an awkward delay between playing the note and it coming out. This is a problem for people who want to be experts at the Ocarina. Also there is an awkward blowing pattern to this, as it takes your mic and measures for loudness, so if there is a loud background, expect some terrible noise.
