Crashes

Doesn’t load with 12.5.8 when opening it. Works on later iOS.
A mute button should be added for the metronome.
Thanks

Wants to charge me again???

This is app does a decent job in all its functions. But with the new update it’s requiring me to repurchase the upgrade that includes Buzz Feinten. And there is not “restore previous purchase” button.

Excellent

Great, easy to use tuner and easy to access metronome. I use the tuner more than my Peterson.

As of 2025

I have used this app reliably for over a decade now. It is a no muss, no fuss, tuner / metronome / chord library.

No hidden in app purchases or subscriptions. Highly recommend.

Great app!

I have had no problems with this app so far. I am also a member of D’addario’s players circle, and I was so excited to see they made an app that I could use with guitar.
