Guitar tuner: C standard tuning

Every string goes down two whole steps: the lowest you can go before switching to a 7-string guitar. Use heavier strings to keep enough tension.

Sound is analyzed on your device. Nothing is recorded or sent.

Automatic string detection. Tap a string to hear it and select it.
