A guitar tuner you don’t have to read.

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

Tune toward green

Red when you’re off, green when you’re in tune, and everything in between as you get close. The whole screen tells you. No needle to read.

Tuning as a Live Activity

Put the phone down and keep tuning. The note and how close you are show up in the Dynamic Island and on the Lock Screen, until you stop playing.

Every tuning

Standard, Drop D, Half Step Down, DADGAD, Open G, Open D, Open E, Drop C, Double Drop D. Build your own from any six notes, down to a low B. A4 is 440 Hz unless you say otherwise.

Down to the cent

Tells you to tune up or down, and by how many cents. When a string lands in tune, you feel a small tap and, if you like, hear the note played back.

Finds the string

Tunic figures out which string you’re playing. Want to tune one at a time? Tap a note to lock onto it. Tap again to let go.

Nothing else

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