From Peter Kastenmaier:
Ever wanted to know how much G you are pulling in your vehicle?This app will provide an indication the amount of G your vehicle is experiencing either by acceleration and braking or cornering. The factors effecting the amount of G your vehicle can achieve is dependent on many factors (weight, power, traction etc). The app will show you the instantaneous G being experienced by the vehicle via a digital readout and also by a moving weight ball. It will also record the maximum G so that you do not have to continually monitor the app.For the app to work correctly your iPhone needs to be firmly attached to the vehicle. Any movement your iPhone experiences that your vehicle does not will be displayed and therefore the G readings will not accurately reflect what is happening to your vehicle. Once your iPhone has been attached to your vehicle you will be instructed to calibrate the iPhone. This will zero any current G force experienced by your iPhone due to not being perfectly vertical and level within the vehicle.The app also allows you to set the scales for both acceleration/braking and cornering. Therefore the depending on you vehicles performance the appropriate scale can be used.
