Tine: Tuner & Metronome

A quieter, steadier tuner: it hears soft instruments in a silent room, holds the needle when a string locks in, and rings a bell. No ads, no account, no tracking.

Tine is a precision tuner, metronome and drone made to feel like the best hardware you've owned. It opens straight into tuning, reads cleanly from across a room, and keeps perfect time.

TUNE ANYTHING • Chromatic tuner with a spring-damped needle, or a true strobe accurate to a tenth of a cent • 40+ instruments and tunings: guitar (6, 7, 8, 12-string), bass (4, 5, 6), ukulele, banjo, mandolin, violin, viola, cello, double bass, winds and brass in written pitch, voice, oud, Highland pipes • Strum check: strum all six strings and see which ones are off • Reliable low notes, down to the 31 Hz low B on a 5-string bass • Octave guard warns before you over-tighten a string • Any reference from 380 to 500 Hz, including 415 Baroque, 442 orchestral and 480 pipes • Historical temperaments: just intonation, Pythagorean, meantone, Werckmeister III, Kirnberger III, Vallotti, Bach/Lehman • "Adopt this pitch": play the piano's A and Tine matches it
