Fork is a tuning fork that listens. Strike it — tap the fork, shake your phone, or knock on the body — and it rings with the long, pure decay of real brass, a haptic pulse in your hand. Then let it listen: Fork hears your instrument and shows the note, with cents deviation on an engraved scale whose brass needle settles like a balance beam. Fork knows what pitch has meant across five centuries. Tune to modern concert pitch, or to A=415 as baroque players do, 432, 442 for orchestras, 444. Choose equal temperament — or just intonation and Pythagorean tuning, with every interval derived from the historical ratios. Strike the fork in any temperament and hear the difference, or tune by the beats between the ringing fork and your instrument: the method musicians used for three hundred years. No accounts. No ads. No noise. A tuning fork, a sheet of paper, and everything a fork should know. — Strike by tap, shake, or knock; haptic feedback; natural brass decay — Listen mode: live note and cents readout from your instrument — Any chromatic note, octaves 2–6 — Reference pitches: A = 415, 432, 440, 442, 444 — Temperaments: equal, just intonation, Pythagorean — with selectable tonic — Designed for iPhone and iPad Fecit Audio — small instruments, made properly.
