ARN Metro

ARN Metro-Tuner brings two essential tools for musicians to your Apple Watch: a haptic metronome and a chromatic tuner. METRONOME Feel every beat through the Taptic Engine. Set your tempo from 20 to 220 BPM using the Digital Crown or tap the TAP button in rhythm to detect your tempo automatically. Choose 1 to 7 beats per measure (1/4 to 7/4) and enable the downbeat accent for a stronger haptic on beat 1. When you change the BPM mid-playback, the phase is preserved — the rhythm doesn't restart from zero. CHROMATIC TUNER Play a note and see it immediately: note name, octave, and cents deviation on a clear visual indicator. The tuner uses the YIN algorithm for accurate pitch detection across the full range of guitar, bass, violin, and voice (25–2000 Hz). When the note enters the in-tune zone (±5 cents), the Watch vibrates — you can tune without looking at the screen. SETTINGS • A4 reference from 415 to 446 Hz — adjust with the Digital Crown or choose from 8 presets (415, 432, 435, 440, 442, 443, 444, 446) • Mic sensitivity: Low, Medium, High • Downbeat accent: on/off Everything runs on Apple Watch — no iPhone needed during use. An extended runtime session keeps the metronome and tuner alive throughout your practice session. User manual available in English at www.arn-music.ch
