Are you interested in finding out what is the acceleration of your car and how modifications effect to the performance ?

This app contains two parts:

- Calculation of car / vehicle performance according to vehicle data and estimation of the effect of modifications, such as increased engine power and torque, weight reduction, gear ratios or tire size change etc. to the performance.
- Measurement of the actual performance. The app uses acceleration sensor in the phone/tablet to avoid problems caused by possible loss of connection to GPS satellites.

Metric or imperial units supported and vehicle data can be saved for later use. Calibration of the measurement is possible as well.

Short guidance:

- Calculation: Fill in all the empty cells, but gear ratios only until highest existing gear. Then push "Calculate" on the Results-page.
- Measurement:
1. Stop the car, situate the cell phone/tablet to a place, where it can't move during driving.
2. Push "Start" and start accelerating the car. The recording of the acceleration won't start before the car is moving.
3. If the 'Automatic stop' is checked, the measurement will stop automatically when the car is not accelerating anymore.
