SpokeTune: spoke tension tuner

Tune bicycle and motorcycle wheel spokes the way you'd tune a musical instrument.

Tap or pluck a spoke and SpokeTune hears the note, measures its pitch, estimates the tension, and tells you exactly what to do: tighten or loosen, in eighth-turn steps. No tension meter needed — just the phone in your pocket.

WHOLE-WHEEL PASSES
Tap every spoke in order and get a worst-first list of the spokes that need attention, compared against your target tension or the wheel's own average. Fix the worst, run another pass, watch the wheel come true.

CALIBRATED TO YOUR WHEEL
A one-time calibration — pluck, turn the nipple exactly once, pluck again — measures how your particular wheel responds, so the turn advice matches reality instead of theory.

MADE FOR REAL WORKSHOPS
A live level meter shows when a tap registers. Unclear taps (too soft, two spokes ringing together) are rejected with a hint instead of polluting your readings. Every pass is saved to a log with per-spoke detail so you can track a wheel over time.

WIDE COVERAGE
Presets for bicycle spokes — plain gauge, butted, bladed, aluminium — and motorcycle wheels, including multi-length spoke sets where each length group rings at its own pitch.

PRIVATE BY DESIGN
No account, no ads, and no network access at all: the app cannot send anything anywhere. The microphone is used only while the listening screen is open; audio is analysed in the moment and never saved.

Works with the traditional wheelbuilder tap test — a spoke wrench or small screwdriver makes a great striker.
