About MPH Tester

Our Mission

MPH Tester provides accurate, accessible, and professional-grade speed testing tools for everyone. Whether you're an automotive enthusiast, researcher, or simply curious about your vehicle's performance, our platform delivers precise GPS-based speed measurements.

Why We Built This

Traditional speedometers can be inaccurate due to tire size variations, wear, and calibration issues. GPS-based speed measurement provides a more accurate alternative by calculating speed directly from satellite positioning data.

Technology & Privacy

All GPS calculations are performed locally on your device. We do not store, transmit, or share your location data. The speed testing functionality works entirely within your browser without requiring account creation.

Data Processing

• Location data processed locally on your device

• No GPS coordinates transmitted to servers

• Real-time calculations without data storage

• No personal information required
