Zero2onehundred is an application that uses GPS to display vehicle speed, top speed, and the elapsed time when traveling from 0 to 100 kilometers per hour.
Zero2onehundred will register your speed when moving, but will not register the elapsed time until you exceed 100kph. Zero2onehundred uses the GPS functions and will only work on 3g enabled devices.
Zero2onehundred will automatically save an image of the screen in your Camera Roll when you complete a 0 to 100 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.
