GrabTime lets you keep track of your working hours simply by using your location to check when you arrive to and depart from your workplace. You can set the time manually for days where this does not reflect your timesheet correctly.
GrabTime uses the iOS location services in a very efficient way, that do not drain your battery. All location information is considered confidential information and is only stored on your iPhone, but you can choose to email your timesheets: Either as a report to be read people or as a CSV report that can be read by IT
systems.
