Seriously. This is it. You need no other.

This app is stunning. Its easy to use and does everything I need it to. I use it to play tones into a Bluetooth speaker for tuning pipe organs. With the custom pitch selection and any temperament you could ask for, this app really has everything. Congrats, app creator friends!!!
