Dragy GPS Performance Meter
The Ultimate Smartphone-Enabled Performance Meter!
Dragy uses Satellites to accurately measure the performance of your vehicle to within 1/10th of a second.
In addition there are many advanced features under development including superimposing performance data over your mobile camera, virtual races with friends, an internal feed for photos and performance discussion, and more to come. Runs are saved in both metric and SAE formats, allowing comparisons of 100-200kmh and all metric equivalents. You can also define your own performance windows for measuring both trap speeds and/or elapsed times, time to brake performance such as 100-0, and much more.
The system can be run simultaneously with JB4 Mobile and other bluetooth apps. Requires the Dragy app which is available free of charge for both iOS and Android.
