iSuspend... Suspension and shock absorber check for any vehicle. Just place your iPhone in a stable position inside the vehicle (e.g. passenger floor), press the start button, accelerate and then gently apply full brakes. That's it: iSuspend records vehicle's oscillations, measures the maximum and minimum pitch, and displays the test results in a graph which may be used to evaluate the status of suspensions and shock absorbers.
