I desperately need an update for your previous “Auto-Tune mobile app”!!

I use Auto-Tune mobile to make music but an updated version of garageband causes the auto tune to be pitched up roughly 50 cents and is unbearable. I have to use an old ipad to create music at this point. It was worth the money and the best Auto-Tune app i have ever installed but i am quite dissatisfied with this mishap and hope it will be fixed soon. Thank you so much!! 😄

Solid, User Friendly Key Detection App

Simple and functional, the pop up keyboard is handy for checking if the key is correct. And the app is free with no ads.
