Besides car performance measuring, it includes news on G-class, stock, AMG versions and tuners versions as well.

Another feature of the app is its unique visualization of the speedometer with color bars illustrating each "target" of the speed or distance you pass.

In all our tests we compared our app results with RaceLogic Vbox (a professional speed measuring device), with an average accuracy at least 95%.
But please keep in mind that the app requires normal GPS signal, and it might work inappropriately in tunnels, near very high buildings and other places with limited sky view.
