PocketDyno measures vehicle performance, providing up to 20 different metrics that report time, distance, speed, acceleration, and power. Create a vehicle profile to store and compare test runs or evaluate vehicle modifications.

PocketDyno is a serious tool that gives **accurate** real-world results. Want proof? More than a million iPhone/iPod touch owners have downloaded PocketDyno or PocketDyno+. Listen to what some of them have to say:

“Not enough stars. This app uses your accelerometer to it's full potential!!!! Accurate results for people who aren't idiots…”

“Suprisingly accurate. This app got within 0.2 mph of the actual top speed and within 3 hp from the actual dyno test. I was shocked!”

****** HOW TO GET ACCURATE RESULTS ******
1) Calibrate just before a test run (temperature effects accelerometers).
2) Enter the exact weight of your car (includes people, fuel, & cargo).
3) Secure iPhone/iPod device in car so it cannot move (we need to measure the car’s motion, not the device bouncing around).
4) Start test run from a dead stop; go when the light turns green.
5) Drive in a straight line on a level track.
6) Read the user’s manual for complete instructions.
