Set to make a formal debut at this year SEMA Show, RageTank.com is looking to bring the racing community from all over the US & Canada together. The new mobile app allows you to select your racetrack for the day, the car you are flogging and the best part is it operates in airplane mode. A great feature since most of our beloved tracks receive little to no cell signal as it is. Once off, the app records your best lap time, top speed and even can calculate your predicted lap time. Other features like the Gas/Food/Lodging buttons can help you find appropriate accommodations within earshot of the track. Bare in mind the app will only work when your smartphone GPS has entered into one of their 335 race tracks coordinates. It will not work for you hooning around your neighborhood or on a canyon run.
