Iron Ear — Tuner & Metronome

Iron Ear puts a real tuner and a real metronome on your wrist. No phone needed, no account, no ads, nothing leaves the watch. TUNER Chromatic, or guitar, baritone, 4-string and 5-string bass presets with a string strip that lights the string you play. Two displays: a needle with a green lock inside 4 cents, or a strobe ring that drifts sharp or flat and freezes when you land it. A4 calibration from 435 to 445 Hz. The mic opens when you raise your wrist to the tuner and closes when you leave. METRONOME 30 to 300 BPM, eight time signatures from 1/4 to 12/8, quarter, eighth, triplet and sixteenth subdivisions, eleven click sounds plus Silent, and tap tempo on the big number. Feel the beat: haptic pulses on your wrist with the accents you choose, so it keeps time in a loud room. It keeps playing while you swipe over to the tuner. MADE FOR PLAYERS Everything stays on the watch. Data Not Collected. Pay once and it is yours. Made by a guitar player. The iPhone app Iron Ear — Guitar Ear Trainer is a separate purchase.
