What's New in Chromtuner

1.3.4

October 19, 2026

REFERENCE TONES THAT SOUND LIKE YOUR INSTRUMENT Click a string, or press a note key, and you now hear that string: plucked steel for guitar, bass, mandolin and banjo, nylon for ukulele, and a bowed string for violin, viola, cello and double bass. Every tone holds exactly the right pitch. A DISPLAY THAT TELLS YOU WHICH WAY TO TURN A quiet caption on the display now says Tune up, Tune down or In tune, and lamps either side of the display light on the side you're off, in the menu-bar tuner too. It settles instead of flickering at the edge of in tune. And the display has glass over it now: a faint sheen and reflection that follow your pointer. Prefer plain LEDs? Turn off Display glass in Settings. A CLEANER, CALMER WINDOW The tuning picker groups tunings by instrument and shows each one's strings. Settings are larger and easier to read, on glass. The string buttons are glass now too, like ChromTuner on iPhone and the web. And Window → Note Window shows just the note you're playing, on a staff, in a small floating window.
