GNSS Speedometer is a simple, lightweight, completely free and ad-free app that uses GNSS (Global Navigation Satellite Systems: GPS, GLONASS, etc). You can use the app in your car, motorcycle, bicycle, and even on an airplane. Accuracy depends on the accuracy of your device's navigation module, as well as weather conditions, terrain, natural and man-made obstacles, and other factors. In any case, your device should “see” some part of the sky for maximum accuracy. FEATURES • Russian and English
