I singing a Christmas caroling group in Chicago and this app is perfect for gigs. I have our entire list of songs along with the keys for each song in one app. It's awesome!The only thing I fear is that the lower pitches can't be heard sometimes when a room has ambient noise. I would love to have a choice of another octave for the C pitch pipe and F pitch pipe. I would also happily pay for the app for the removal of the ads!

This app is great! I love the “Songs” page feature where I can save my list of songs and set up their pitches beforehand. Just make sure you lock the rotation on your phone before using; if you press a note and your phone orientation rotates then it will lock that note and keep playing it until you close the app. I only wish I could pay for this app so it would not have the small ads. At least they are not pop-up and disruptive ads. I just have to be careful to not click them. I mostly use this app on airplane mode anyway.

Downloaded this app for an a capella gig. Sweet, I thought, no need to go buy a fancy pitch pipe. Bugs within the app wreaked havoc on our performance. Ordinarily I would forgive and forget, but there’s no forgetting the horrors of singing Semi-Charmed Life in 4 different keys in front of 100 seniors.Basically, the app got “stuck” and started playing multiple pitches at once, making it impossible for me to play and hold the “right” pitch :(

Love this app, because I can keep a whole set list for our a cappella quartet :-) Would love it if you could add a 432 Hz button like the tonal energy app has.
