FAQ

What is the difference between Richter and Power Bender?
Richter is the standard tuning on most diatonic harmonicas. Power Bender and other alternative tunings like Paddy Richter, Country, and Natural Minor rearrange notes to make certain bend or chord
patterns easier. Try them in the in-app tuning menu.

Does it work without internet?
Yes. Once installed, no internet is needed. The tuner runs entirely on your device.

What permissions does it need?
Microphone access only. Audio is processed locally and never uploaded.
