DriveStudy

DriveStudy enables research institutions to collect and use driving behavior data for the purposes of a specific study. It automatically detects when driving starts and stops and uses the phone’s sensors to measure your vehicle’s driving dynamics. It also acts as a low-power logger of all of your driving trips. 

DriveStudy runs in the background and uses GPS. Continued use of GPS running in the background can dramatically decrease battery life. DriveStudy uses low-power sensing methods to reduce battery consumption as much as possible.
