PocketDyno™ transforms your iPhone or iPod Touch into an automotive performance meter. With it you can measure your vehicle's horsepower, your 0-60 and quarter mile time and much more all for the price of a hamburger and fries.
PocketDyno uses the iPhone’s built-in accelerometer to measure the drag racing performance of your vehicle. Hone launch techniques, reaction time, and shifting skills. Compare results before and after vehicle or engine modifications. It's like having a dragstrip in your pocket!
