Zero2sixty is an application that uses GPS to display vehicle speed, top speed, and the elapsed time when traveling from 0 to 60 miles per hour.
Zero2sixty will register your speed when moving, but will not register the elapsed time until you exceed 60 mph. Zero2sixty uses the GPS functions and will only work on 3g enabled devices.
Zero2Sixty will automatically save an image of the screen in your Camera Roll when you complete a 0 to 60 run. Just click on the Photos Icon and look in the Camera Roll for copies of the screen. Post them online, share them with your friends, print them and stick them in the rear window of your car.
