timeasy is an open source app you can use to track your working hours fast, easy and intuitive. You can start your time tracking just by tapping the play button. When you start the tracking the play button automatically changes to a pause-button where you can stop the timing. The time tracking does not depend on the app constantly running. You can even shut down your phone and the time tracking will go on. In the weekly overview you can see how many hours youve worked in a specific week. When opened it shows the current week. You can swipe to the left or right to switch between weeks. You want to know exactly when and how long youve worked? Just open the working hours oveview. Here you can see all time entries in detail, edit them, delete them or add new entries manually.
