Car Performance Meter is a simple and transparent app for testing performance of your car or any other vehicle. It can be used for testing performance of a car, motorcycle, boat and others. Draging and braking tests use automatic start-stop and write the measured speed and distance data on the chart. Accurate approximation algorithms are used on devices with slow GPS update rate. You can fully customize benchmark parameters of the drag and even use freestyle mode with a racing car style speedometer and stopwatch.
