Needs an update !!

Needs an update! Doesn’t talk to the mic on Iphone xs os12.1 ! Love the temperament selections. A small tweak would fix all this. Emailed the admin with no response!

As someone who tunes professionally for a living, this app is a godsend for harpsichords and clavichord Tuning. Generally I tune by fork and I can do many historic temperaments that way, but with the pitch pipe on this; it is a whole new level with so many more options. Love this app! And let me just also note: the interface is so easy to use. Perfection all the way around.

Was great...

This app worked great for me until updating to 12.1. Now, the tuner does not work. Only the pitch pipe works. I tried restarting my phone, and even reinstalling the app. Before this update, I loved how this app made tuning the harpsichord such a breeze. Setting temperaments makes the music come to life! Please update ASAP.
