Tune the untunable.

A precision strobe tuner built for handpans and other multi-modal instruments where one strike sounds three notes at once.

Read the fundamental, octave, and 12th as independent strobe bands. Isolate any two chosen frequencies with the Spectrum Analyser to reveal their dedicated strobe bands.

Why V-Tune

Built for instruments that sing in chords

Three-band strobe display

See the fundamental, octave, and 12th as independent strobe bands. Motion means drift; stillness means locked.

Per-band pitch pipe

Hear the reference tone for any band — continuous, or a beep that fires on each strike so you can match by ear.

Live note detection

The note your mic picks up lights up on the pitch wheel in real time, so you always know what you just struck.

Handpan scales built in

Kurd, Amara, Celtic and more — the ding highlighted, every note at its real octave.

Spectrum analyser + isolation

See the full frequency content, then bracket any peak to give it its own dedicated tuning band.

FFT + phase-rate Goertzel

Peak detection finds the loud frequencies; phase-rate analysis measures how stable each one is, frame to frame.

Your sound never leaves your device

V-Tune processes microphone audio entirely on-device, in real time. Nothing is recorded, stored, or transmitted. No accounts, no analytics, no ads, no network requests — the app works fully offline.
