DigiHUD Speedometer

100% ad-free, doesn't require data/cell connection to work.

DigiHUD Speedometer is a free GPS based digital head up display (HUD) that shows useful speed and distance information for your journey. Ideal if your vehicle speedo has died, you want to verify your vehicle speed or you just want to know your speed when cycling, running, flying, sailing etc.!
The display can be switched between normal viewing and HUD mode which mirrors the display for viewing as a reflection in a vehicle windshield (most useful at night, depending on the device's brightness). 
DigiHUD can open as a floating window on top of other apps or your homescreens. Works with external GPS receivers (tested at 10Hz). 

Although we strive to make all readings as accurate as possible they are only as accurate as your device's GPS sensor and should only be regarded as approximations.

For more than a dozen extra features, with many more planned, try DigiHUD Pro (link at the bottom of this description).
