Magnetic Flux — A GPS speedometer for cyclists
The moment you pedal, your speed is displayed.
Simply turn on the app and start riding without any complicated settings.
[Real-time GPS Speed Measurement]
It directly analyzes GPS signals to display your current speed in real-time.
Noise filtering eliminates errors from stationary states, showing only accurate speeds.
The speedometer gauge intuitively changes from low speed (green) → medium speed (yellow) → high speed (red).
