GPS Speedometer Online
Real-time speed in km/h and mph, top speed, distance traveled and active time. Nothing to install. Your location never leaves your device.
Everything the speedometer measures
Far more than just instant speed.
Real-time speed
The dial shows km/h and mph at the same time, updated continuously thanks to the GPS sensor.
Top and average speed
Logs your peak speed and automatically calculates the average speed for the current trip.
Cumulative distance
Calculates the distance traveled using the Haversine formula with filtering of GPS jumps.
Active time
Built-in stopwatch that measures the exact time since the GPS first locked on.
Running pace (min/km)
Switch to pace mode and instantly see your tempo in minutes per kilometer — perfect for training.
Compass and heading
View your heading in degrees and cardinal direction (N, NE, E…) using the device's GPS sensor.
Altitude and elevation gain
Shows the current altitude in meters and totals the positive elevation gain along the trip.
Speed history
Live SVG sparkline with the last 30 readings so you can watch how your pace evolves.
Configurable alerts
Set a threshold between 30 and 200 km/h. The screen warns you visually whenever you exceed it.
Save your trips
Stores each session (distance, top, average, duration, elevation) on the device itself, with no server involved.
GPX and CSV export
Download the full trip track as GPX (works with Strava, Garmin) or CSV for further analysis.
Total privacy
All the logic runs in your browser. No GPS coordinate ever leaves your device.
Track, save and export your trips
Every session is logged with average and top speed, distance, duration and elevation. Save it on your device or export it to GPX to load it into Strava, Garmin Connect or Komoot.
Real-time history
SVG sparkline with the last 30 speed readings so you can watch your pace evolve live during the trip.
Trips saved locally
Stores up to 50 trips in localStorage. Each one keeps date, average and top speed, distance, duration and total elevation gain.
Export to GPX or CSV
Download the full track as GPX 1.1 (works with Strava, Garmin, Komoot, Wikiloc) or as CSV for analysis in Excel or any spreadsheet.
Real privacy: saved trips never leave your device. Office Tools doesn't receive any coordinates, speeds or files. All persistence happens in the browser's local storage.
