Intonaire - Tuner & Metronome

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.

■ Built to last
- Korean, English and Japanese
- Backup & restore so your history survives a device change
