iPhone
A calm tuner for guitar, bass and ukulele, with chromatic mode and reference pitch from 430 to 450 Hz. No ads or accounts. Audio stays on your device.
Fork is a tuner that does one thing well.
Play a string. The note settles, the dot centres, the screen goes still.
That stillness is how you know you’re in tune.
Choose guitar, bass or ukulele for automatic string detection, or use chromatic
mode for any note in the tuner’s range. Standard tunings: guitar EADGBE,
four-string bass EADG, and ukulele GCEA with a high G.
Set your reference pitch from 430 to 450 Hz. The string targets follow your
chosen reference. Turn haptics on for a quiet cue when a string settles in tune.
Fork listens through the microphone. Audio is processed on your device, in the
moment, and is never recorded, stored or sent anywhere. No ads, accounts or
analytics.

Bass and ukulele join guitar and chromatic mode.
Choose your instrument for automatic string detection: standard four-string
bass EADG or high-G ukulele GCEA. Low-note detection now reaches bass low E.
Controls give a small tap back, and the haptics switch controls every buzz.
