Simple TunerIn tune, the moment you open it.

A warm, analog guitar tuner for iPhone — plus genre scale maps for blues, folk, soul & reggae.

Just play

Open the app and it's already listening. Pluck a string and the big display shows exactly where you are and which way to turn.

It knows whether you're on the low E or the high one, so there's nothing to tap. Lock to a single string when you want to stay put.

A pocket reference grouped by feel — tap any scale to see it on the fretboard, transpose to any root, and save your favorites.
