If you have selected a default shift and have come on time, setting the start time is not necessary. You simply tap the Stop button
at the end the day. So the end is recorded, the beginning and the pause duration are filled in in accordance with the standard shift. You can enter your roster on the roster page. A roster entry is given priority. For example, if your default shift is "early", but in the roster was entered „late" for today, the late shift is correctly taken into account.
If you have forgotten to take your time, that's no problem. Insert a new entry by touching the Stop button (if you have entered a default shift). Then tap the new entry - now you can adjust the start, end and break times.
