Stay in tune, together
Two modes. Reference tones always work — play the pitch and tune by ear. Mic mode listens to your instrument and shows the note and how many cents sharp or flat you are. (Mic mode needs HTTPS — reference tones work everywhere.)
Tap a pad to sound the reference pitch, adjust your string, repeat. For a guitar: low E → A → D → G → B → high E.
