Free guitar tuner FAQ
Is this an online chromatic guitar tuner?
Yes. Chromatic mode follows the nearest note; Auto String follows your six selected tuning targets. Needle and strobe use the same pitch measurement.
What does Attack Check measure?
It compares pitch push and relative input levels across nine plucks. This guitar tuner with string gauge guidance estimates a hand band for this session, not physical force or a laboratory measurement.
Is my microphone audio private?
Audio stays in your browser. Nothing is recorded or uploaded. The microphone stops when you stop the tuner or hide the page.
