Intonaire

The one practice companion for string players, Intonaire. When your pitch is right, the screen glows clear and bright. When it drifts, it fades. More than numbers on a dial, Intonaire lets you feel whether your sound is in tune. ■ Precision Tuner Supports violin, viola, cello, double bass, guitar and ukulele. Pick your instrument and the strings on the fingerboard change; the moment you land in tune it glows gold and gives a gentle haptic. Set your reference pitch freely — 415, 440, 442 Hz and more. ■ Pitch Mirror Your pitch is drawn as a live curve in real time. Watch your long tones for wobble and check the evenness of your vibrato as you play. ■ Metronome (digital + analog) A crisp digital click, plus an analog mode with a swinging pendulum and warm wooden ticks. Time signatures, accents, and a speed‑trainer that gradually picks up the tempo. ■ Drone Hold a sustained reference tone and tune over it — the classic way string players train intonation. ■ Practice Log & Stats Record your practice and keep it on the calendar. See monthly and ranged practice time, per‑instrument stats, streaks, and daily goals at a glance.
