How to Use

- Just got to work? Pick your work hours and press the "Clock in now" button. The start time becomes now and the end time is set that many hours later. You can still edit both fields afterwards.
- Press the full screen button or double-tap the clock to show only the clock. After a few seconds without input, the button and mouse cursor disappear.
- Leave full screen with the Esc key or the same button. On a tablet the clock resizes for both landscape and portrait.
