About SpeedSmeter
Your trusted GPS-based speed measurement tool for accurate real-time velocity tracking.
Our Mission
At SpeedSmeter, our mission is to democratize access to high-precision telemetry data. We believe that professional-grade speed measurement tools should be accessible to everyone—from competitive cyclists and runners to daily commuters and curious travelers—without the barriers of expensive hardware or complex software installations.
We are dedicated to building the world's most accurate, privacy-focused, and user-friendly browser-based speedometer, empowering users with real-time data they can trust.
Why Choose SpeedSmeter?
In a world of data-heavy apps and subscription-based services, SpeedSmeter stands out by offering a pure, streamlined experience:
Zero-Install Technology
Our advanced PWA (Progressive Web App) technology allows you to use GPS tracking directly in your browser. No downloads, no app store credentials, just instant access.
Privacy First
We believe your location data belongs to you. All GPS processing happens locally on your device. We do not store, track, or sell your movement history.
Cross-Platform Precision
Whether you are on iOS, Android, Windows, or macOS, our responsive engine adapts to your device's sensors to provide the most accurate reading possible.
How It Works
SpeedSmeter leverages the Geolocation API built into modern web browsers to verify your position against a network of 24+ global navigation satellites. By calculating the Doppler shift and time-delay of these signals, we can determine your ground speed with remarkable accuracy—often within 0.1 m/s.
Our proprietary algorithm filters out "GPS noise" and signal drift, ensuring that when you are stationary, your speedometer reads zero, and when you move, it reacts instantly.
Who We Are
SpeedSmeter is built by a team of web performance engineers and data visualization enthusiasts passionate about the intersection of physical motion and digital tracking. We started this project to solve a simple problem: "How fast am I going right now?"—without the need for native apps.
Since our launch, we have helped thousands of users—from train passengers verifying their commute speed to cyclists tracking their downhill sprints—gain better insight into their travels.
