View on GitHub

A TypeScript client for the Web Bluetooth API that talks to force-sensing climbing hardware: Griptonite Motherboard, Tindeq Progressor, PitchSix Force Board, Kilter Board, Entralpi, Climbro, mySmartBoard, WH-C06, Frez Dyno, and more. Use it to stream force data, drive games, or build training apps on web, Capacitor, React Native, or the CLI.

Browser support

Web package requires Chrome, Edge, or Opera (Web Bluetooth). See Browser support. For iOS, use Capacitor or React Native.

Why use it ​

  • One API - Same connect, notify, stream, download across all supported devices.
  • Multi-platform - Web, Capacitor, React Native, and Node.js / Bun / Deno via Runtime and CLI from a single codebase.
  • TypeScript - Full types and device interfaces for tree-shaking and IDE support.
  • Battle-tested - Used by HangTime and Heli-Hero and open-source examples.

Get started in 3 steps ​

StepAction
1Install the package for your platform (Web, Capacitor, React Native, Runtime, or CLI).
2Follow the Quick start guide: connect, subscribe to data, and stream in a few lines.
3Pick your device and use device-specific APIs (battery, LED, stream, download).

Features ​

  • Connect - Pair with force-sensing devices over Bluetooth LE; same flow on all platforms.
  • Stream - Real-time mass/force via notify(): current, peak, mean, and optional distribution (left/center/right zones).
  • Activity - active() callback with configurable threshold and duration for “user is pulling” detection.
  • Export - Download session data as CSV, JSON, or XML.
  • Multi-platform - Same API on web, Capacitor, React Native, and Node.js / Bun / Deno via Runtime and CLI.

Live demos ​

DemoDescription
ChartStream force from your device and watch it plotted live. Ideal for testing connection and seeing mass/force values in real time.
Flappy BirdPull on your hangboard to fly the bird; pull strength controls altitude. Game and workout in one.
Kilter BoardSend a route from the browser. Your Kilter or compatible LED board lights up the problem on the wall.
PongMove the paddle by applying force to your device. Minimal game loop that shows streamed force as input.
