This App allows you to measure most of your car performance tests:
1) 0-60 mph, 0-100 mph acceleration etc
2) 1/8 mile, 1/4 mile (quarter mile) and other drag-racing results
3) maximum speed achieved
Also, your previous results are saved in history table with simple visualization.
Another feature is the unique visualization with color bars illustrating each "phase" of the speed or distance you achieve. This unique manner greatly helps to quickly understand the approximate speed/distance passed with at first glance. This greatly improves safety while driving and makes the interface more intuitive.
And since GT1.com organizes or co-organizes car events, the app has been tested on multiple cars, from classic muscle cars of the 60s (Chrysler 300, Dodge Charger, Ford Mustang, Chevrolet Camaro) to the modern Japanese sports cars like Nissan GT-R, Skyline, Toyota Supra, and others.
In all tests there also was used RaceLogic Vbox professional equipment, with an average accuracy of the App shown being at least 95%.
Please keep in mind that due to the limited satellite signal, the app might measure improperly when tested in a tunnel, near high buildings and some other locations.
