Simple Speedometer

Simple Speedometer is a free GPS based digital head up display (HUD) for Android that shows useful speed information for your journey. Ideal if your vehicle speedometer has died, if you want to verify your vehicle speed or if you just want to know your speed when you are driving, cycling, walking, running, flying, sailing...

Simple Speedometer only uses high contrast screen colors to spare your eyes.

Simple Speedometer supports:
-Night, day and auto color mode
-Multiple speed units; ft/s, km/h, kn (kt), m/s and mph
-Keeping screen on

Do not use Simple Speedometer when you are swimming unless your cell phone is waterproof! :P
