The description of Rallycheck App
Rallycheck.com checks your rally route and replaces passage controls using GPS positioning.
The Rallycheck app displays the passage control on your screen. You decide if you want to record the passage control. The passage control is shown on the display when you are in the immediate vicinity of the location where the rally organisation has placed the control.
The passage control is no longer physically located next to the road, but is shown only on your display.
Using Rallycheck you never miss a control. All recorded passage controls are saved digitally en this enables the rally organisers to calculate the results in a timely and correct fashion.
