custometer

Within the app you can combine different modules to your personal layout - or use ready-made ones. For each module you can define a color - or use a predefined color scheme. You have the choice. 
The following modules are available:
-A speed display (in km/h or mph)
-A map that shows your location
-A battery indicator (in %)
-An altitude display (in m or ft)
-A watch
-A street display
-a compass
-An overview (with highest speed, highest altitude and distance traveled today)
-A navigation module
-A distance display (how much you have driven today)
-A top speed display

You can also view your speed, distance and altitude over time in the statistics.

Use the app as a construction kit for your own speedometer.
