Pianotune · iPhone & iPad
Concert-grade tuning, in your pocket.
The scientific rigor working tuners trust over their own ears — full 88-key inharmonicity sampling, Railsback stretch curves, pitch-raise overpull — in a modern iOS interface with per-piano history and sync.
For technicians & serious players
Tune one piano — or a hundred.
Pianotune remembers every measurement, so every return visit starts where the last one ended.
Real-time pitch detection
Cents-accurate needle and strobe display on a full 88-key strip, with auto-detect and manual key override.
Learn-My-Piano
Full chromatic inharmonicity sampling builds a unique B-coefficient fingerprint for the exact instrument in front of you.
Railsback stretch curves
Stretch computed from the piano's own measurements — not a canned curve — so octaves ring true top to bottom.
Pitch-raise overpull
Overpull modelling for pianos far off pitch — get there in one pass instead of three.
76 temperaments
From equal to Werckmeister to Kirnberger — historical temperaments for period-accurate work.
Per-piano history & clients
Cloud-era workflow: every piano's measurements, tunings, and client details, synced and searchable.
The tuner your ears will trust.
Pianotune is in final preparation for the App Store. Watch the Alpine Squad homepage for launch.
