Worktime is a time tracker (time sheet and time recording app) that makes it really easy to keep track of the time you spend at work. It records the time automatically - so you don't have to remember to punch-in and punch-out. It also shows the flex time and presents the times in a simple and easy overview.
Worktime works by looking for presence of a Wi-Fi network at your workplace and does not need to use the GPS, which means no additional battery consumption. There is no need to be connected to the Wi-Fi network.
