About SpeedometerOnline.com
SpeedometerOnline.com is a free web tool that answers one simple question: "How fast am I going right now?" Since launch, millions of speed checks have been run by curious passengers on trains, drivers verifying their dashboards, cyclists tracking rides, and travellers on buses, boats and planes around the world.
Our mission
We believe simple utilities shouldn't require installing an app, creating an account, or giving up your data. Everything on this site runs directly in your browser using your device's own GPS and sensors.
What we offer
- GPS Speedometer — live speed in km/h, mph, m/s and knots, with trip distance, max/average speed, speed alerts and a night HUD mode.
- Train, Bus & Car speed checkers — tailored guides for each vehicle.
- Speedometer test — check your dashboard speedometer accuracy against GPS.
- Full screen speedometer — giant digits for dashboards and bike mounts.
- Online compass — find your heading in degrees, right in the browser.
- Elevation finder — check your current altitude.
Privacy first
Your GPS position, speed and sensor readings are processed entirely on your device. We do not collect, store, transmit or sell your location data — ever. When you close the tab, nothing remains.
Accuracy
GPS speed is typically accurate within 1–2 km/h under open sky. We display a live GPS-accuracy indicator so you always know how reliable the current reading is. Our tools are guides for information and fun — always rely on your vehicle's instruments and obey local traffic laws.
