TuneHaven
Guitar · bass · ukulele · violin — 18 instruments & voice
The tuner that never guesses.
Cheap tuners flash “in tune” early, jump to the string they think you’re playing, or read a harmonic and send you tuning up until a string snaps. TuneHaven asserts nothing it can’t actually know.

Honest by design
It asserts nothing it can’t actually know
-
Never switches strings behind your back
It may suggest — you decide. Your tuning session stays yours.
-
Rejects octave errors
The mistakes that make other tuners read low strings wrong get filtered out.
-
Refuses to read a room it can’t trust
Rather than showing you noise, it tells you it can’t hear you clearly.
-
“In tune” means in tune
The needle is live and honest — no freezing, no early green.

Free means free
Free forever — in writing

Private by architecture
Nothing you play ever leaves your device
TuneHaven works fully offline — the app doesn’t even request the Internet permission, so it cannot transmit anything. One permission, the microphone, and audio is analysed on the device and immediately discarded. Don’t take our word for it: read the privacy policy — nothing collected, nothing shared.
TuneHaven Pro is a one-time supporter unlock — the chord library beyond major & minor, the course levels past the fundamentals, practice history & insights, String Health, the overtones view, extra colour palettes and a thank-you badge. Never a subscription, and nothing you already rely on will ever move behind it.
