The Open Road Race Timer is a specialized application for high-speed automobile racing on closed highways. It allows racers to set precise target times based on a combination of speed and distance. Users can input speed, distance, and starting time to compute the target time for the race. The app features countdown functionality to the race start and offers the option to fine-tune time adjustments down to ten-thousandths of a second.

For added precision, users can synchronize the app's clock with the official race clock. Speed settings range from 60 to 170 mph in 5 mph increments, catering to various racing conditions. The app also allows for detailed GPS inputs, including Finish Line coordinates, to compute time errors accurately. Users can track their performance against ideal time and distance measurements, making it a valuable tool for competitive racing scenarios.
