This application is designed for drivers quality analyzing. It shows how quietly the driver is driving his car. This application uses just accelerometer of your iPhone or iPad. It doesnt used GPS at all.
It is like electronic glass of water on your head panel.
The quality of driving is calculated by trembling of accelerometers sensors. There is three levels of trembling. Moving level, First level and Second level. You can tune it via Settings page.
Expert page shows you graph of your driving quality and details parameters of your accelerometers and needed parameters for calculation of drivers quality.
Help page can give some description of work and settings.
I hope you will get a lot of positive emotions and this application will increase your drivers level.
Good luck with Drivers Analyzer.
