Live GPS Speedometer Online | Track Speed in km/h & mph

Turn your smartphone into a highly accurate digital dashboard. Use our free web-based GPS Speedometer to track your live travel speed, monitor your maximum velocity, and log your trip distance without downloading any heavy apps.

How the Live Web Speedometer Works

Unlike traditional car speedometers that measure the rotation of your vehicle's tires, our online speedometer uses your device's internal GPS hardware. By calculating the exact time it takes your phone to travel between satellite coordinates using the Haversine formula, it outputs a highly precise real-time speed.

Key Features

• No Installation Required: Works entirely inside your mobile browser (Chrome, Safari, Firefox).
• Dual Unit Support: Seamlessly switch between Kilometers per Hour (km/h) and Miles per Hour (mph) without corrupting max speed or trip data.
• Trip Telemetry: Automatically logs your maximum peak speed and tracks your total distance traveled since you pressed “Start”.
• Privacy First: Your location data is processed locally on your device. We do not store, save, or transmit your physical coordinates to any servers.

Why is the Speedometer showing 0 or failing to track?

If the gauge is not moving, ensure the following:

1. You have granted location permission to your web browser.
2. You are currently outdoors. GPS signals often perform poorly indoors, under concrete roofs, or in basements.
3. You are physically moving. Desktop computers usually do not have GPS chips and may not work correctly with this tool.
