Climbing Force Gauge

Climbing Force Gauge is a finger-force instrument and training ledger for climbers. Connect a BLE force gauge (Web Bluetooth, Weight Scale service) and run the standard 7:3 protocol on a 20 mm edge: the app streams force at 10–80 Hz, scores every rep from the raw force-time curve — peak, sustained mean, impulse in N·s, rate of force development over the first 200 ms, time in the target band — and excludes botched reps (no pre-load, bailed, too short) instead of silently corrupting the numbers. The critical force is fitted as mean force per rep against 1/work-time (asymptote plus a W′-analogue) and is always shown with its residuals and confidence band, never asserted as a single number. Everything normalises to bodyweight and to your MVC baseline, and unilateral runs produce a left/right asymmetry figure. The core of the app is the ledger and its scheduler: every grip position × edge depth keeps its outcome history, each item's decay half-life is estimated from your own re-tests, and the TODAY block tells you what to work — a stale item to test, an aging one to load lightly — and greets you after three weeks away with a re-baseline plan rather than a broken streak. A standard-protocol run compares as a percentile against everyone who ran the identical protocol (signed-in, aggregates only, never a leaderboard). No gauge? Import a force-curve CSV or enter a measured result by hand and the ledger, scheduler and cohort stay fully alive; a built-in simulator runs the whole pipeline for demonstration. Raw curves stay on your device in IndexedDB; only the compact derived ledger syncs to your VibePlat account. The interface follows the viewer's locale in English, Chinese, Japanese and Spanish.
