Intonaire vs Advanced Tuner

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. ■ Built to last - Korean, English and Japanese - Backup & restore so your history survives a device change - iPhone, iPad and Mac (Apple Silicon) No ads. No subscriptions.

Advanced Tuner is a free guitar tuner and chromatic tuner that also handles bass, violin, ukulele, mandolin, viola and cello. Play a string, read the needle, done: tuning to the cent, with no menus in the way. TEN TUNINGS, READY TO GO • Guitar: standard EADGBE, Eb (half step down) and D (full step down) • Bass, ukulele and mandolin • Violin, viola and cello • Chromatic mode for everything else: it finds the nearest note on its own AUTOMATIC OR STRING BY STRING Leave it in automatic and it follows whatever you play. Or pick a string and it holds it, so a fret buzz or a neighbouring string cannot steal the reading. YOUR OWN TUNINGS Drop D, open G, DADGAD, seven-string guitar, banjo, baritone ukulele. Name each string, set its frequency, save it. Up to 7 strings per tuning. TUNE BY EAR TOO Tap a string to hear it, recorded from the real instrument. Useful for a wind instrument, a voice, or anywhere a microphone struggles.
