Great a cappella pitch pipe – TUNE - Smart Chromatic Tuner Review

Downloaded this to use for an a cappella duet. Love that I can set the frequency (for $2 upgrade that's still a cheap pitch pipe) since we wanted to try 432. We can also watch the app as we sing to see if we're going flat. So helpful! And the simplicity is perfect.
