A guitar tuner you don’t have to read.

Play a string, tune toward green. That’s it.

Tune toward green

The screen responds to every string: red when you’re off, filling toward green as you get close. No needle to squint at.

Down to the cent

Tells you to tune up or down and by how many cents, with a small haptic tap and the note played back softly when a string lands in tune.

Finds the string

Tunic follows whichever string you play. Want to tune one at a time? Tap a note to lock onto it, tap again to let go.

Every tuning

Standard, Drop D, Half Step Down, DADGAD, Open G, Open D, Open E, Drop C, Double Drop D. Or build your own from any six notes.

Your reference pitch

A4 = 440 Hz by default, adjustable if that isn’t your thing.

Nothing else

No account, no ads, no tracking. Audio never leaves your phone. Get in tune, get back to playing.
