The easiest way to track your performance on the fly!

Monitor your 0-60mph, 1/4 mile, 60-130mph, 100-200kmh, 1/2 mile performance, and more!

Dragy uses multiple high speed GPS satellites to accurately measure the performance of your vehicle within 1/100th of a second, producing identical results to the much more expensive and cumbersome Racelogic Vbox system, in a less expensive and easier to use package. The Dragy software automatically charts slope on all timeslips which you can then post to forums or social media, share with friends, or even upload to the Dragy leader board. Dragy has an amazing video overlay feature. The Dragy box is extremely compact at 1" x 3" (25.4mm x 76.2mm) with a magnetic base and can be set on the dash when testing and stored in the glove box or center console when not in use.

In addition, there are many advanced features under development including 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 dragy system can be run simultaneously with JB4 Mobile and other Bluetooth apps. Requires the FREE Dragy phone/tablet app which is available for both Apple® iOS and Android® devices. The dragy reviews don't lie. This is a great product!
