Professional Tuner

Open it and tune — guitar, bass, ukulele, cavaquinho and mandolin, with the precision you'd expect from a real instrument.

Tune your instrument the way it deserves to be tuned.

No ads. No account. No subscription just to see if a string is flat. Open the app, play a note, and get an instant, precise reading — the way a real instrument should feel, not a cluttered utility.

Works with guitar, bass, ukulele, cavaquinho, and mandolin.

TUNE YOUR WAY Pick a string and tune to a fixed target, or let Chromatic mode detect whatever note you're playing — no guessing which string is which.

MONITOR MODE See all your strings at once. Watch the pitch move in real time and spot the one that's off in a glance.

REFERENCE TONES Not sure what a string should sound like? Tap to hear it before you tune.

BUILT FOR PRECISION Set your own reference pitch (A4), and switch between standard and alternate tunings — Drop D, Open G, DADGAD, and more.

PRIVATE BY DESIGN All audio is processed on your device. Nothing is recorded, stored, or sent anywhere.

Whether you're warming up before a gig or tuning between takes, this is the tuner you'll actually want to keep on your home screen.
