TuneHaven: Guitar Violin Tuner

Cheap tuners guess. They 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 is a tuner that asserts nothing it can't actually know: • It never switches strings behind your back. It may suggest; you decide. • It rejects octave errors that make other tuners read low strings wrong. • It refuses to read a room it can't trust instead of showing you noise. • "In tune" means in tune. The needle is live and honest, with no freezing and no early green. Free means free. Every instrument, every tuning, the chromatic mode, custom tunings and reference tones: free, forever. No subscription, no ads, no account, no tracking. TuneHaven works fully offline, so nothing you play ever leaves your device. Don't take our word for it: check the Data safety section below. Nothing collected, nothing shared. The microphone is the only access to anything of yours the app asks for, and audio never leaves your phone.
