Intonaire
Tuner, metronome & practice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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. Watch your progress build.
