Speedometer (Speedometers.live)
A free, private GPS speedometer for Android, built from the web tool at speedometers.live.
- Live speed from GPS in five designs: Night Drive, Sport, Glass, Clean & Modern and Map + Gauge
- Gauge, large digital and mirrored HUD display modes
- Trip statistics: current, max and average speed, distance, time, altitude, heading, GPS accuracy, 10-minute speed chart
- Live route map (OpenStreetMap, or Esri satellite imagery)
- Trip history saved on the phone
- km/h, mph, knots and m/s
- Screen stays on while open, phone and tablet layouts, light and dark mode
Privacy: no accounts, ads, analytics, trackers or Google Play Services. Location is used only while the app is open, and speed, position and trips never leave the phone. The only network requests are map images from OpenStreetMap and Esri. Full policy: speedometers.live/privacy-policy/#app.

How it's built
The app is a Capacitor shell around the same speedometer the website uses.
| Path | What it is |
|---|
src/markup.html, src/speedometer.js, src/speedo-v2.css | The speedometer tool from the website |
src/app-shell.css, src/app-bridge.js | The app layer: full screen, safe areas, theme, GPS restarts, status bar, back button |
build-www.js | Builds www/ from src/, with Leaflet and the Inter font bundled so nothing loads from a CDN |
android/, ios/ | Native projects (the iOS project is set up but not yet released) |
assets/, design/ | Icon and splash sources, and the scripts that render the icon and store images |
fastlane/metadata/android/ | Store listing text and images, read by F-Droid and IzzyOnDroid |
GPS comes from the WebView's standard geolocation, which on Android reads the platform LocationManager. No Google libraries are used.
Build
Requires Node.js 22+, JDK 21 and the Android SDK (platform 36).
npm ci
node build-www.js
npx cap sync android
cd android
./gradlew assembleRelease
Without a signing key the release APK is unsigned. To sign, create android/keystore/keystore.properties with storeFile, storePassword, keyAlias and keyPassword. That folder is ignored by git.
node build-www.js --fetch first downloads the latest tool from speedometers.live into src/.
Development and AI assistance
This app was developed with substantial help from an AI coding assistant (Anthropic's Claude), which wrote much of the app layer, build scripts and store assets. Each release is tested on an Android emulator (GPS, map, permissions and back button) before it is published. Bug reports and pull requests are welcome.
