Harpie – Harp Tuner

DESIGNED FOR HARPISTS
Harpie is not a generic chromatic tuner with a harp mode bolted on. Every detail — the lever and pedal harp string list, the reference tone synthesis, all-flats note display, the A4 calibration — was built around how harpists actually tune.

Whether you're tuning up before a rehearsal or dialing in precise calibration before a performance, Harpie gives you the clean, responsive feedback you need.

TUNER
The arc gauge shows exactly how sharp or flat each string is, with a clear indicator so you know at a glance whether to tighten or loosen.

REFERENCE MODE
Tap any string in the list to play back a pure harp reference tone. Tune by ear or let the gauge guide you - your choice.

PEDAL HARP
Full 47-string layout, with all pedals set to flat as a starting point.

LEVER HARP
Configurable 19 to 40 strings. Choose the layout that matches your instrument.

CALIBRATION
Set A4 anywhere from 430 Hz to 450 Hz in 1 Hz steps. Preference for flats or sharps. Octave display on or off.

DARK MODE
Full dark theme support — easy on the eyes in low-light rehearsal spaces and pit orchestras.

TUNING REMINDER
Before each session, Harpie reminds pedal harp players to set all pedals to flat and lever harp players to disengage all levers — so your starting point is always consistent.

Supports English, German, French, Italian, Simplified Chinese, and Traditional Chinese.
