The Timer Screen
The timer screen will normally look similar to this.
The three control buttons are at the top. On the left is the Restart button, then the Start/Stop button in the middle and the Cancel button is on the right.
Just below the Start/Stop button is the current task name.
Information for the current shift and the previous shift is shown at the bottom.
Restarting & Cancelling
These work diffently depending on whether the current shift has started or not.
If the current shift has not started, tapping the restart button will set the last shift running as if it had never stopped. Tapping the cancel button will completely clear the last shift.
If the current shift has started, tapping the restart button will set the current shift start time to now. Tapping the cancel button will clear the current shift completely.
The restart and cancel buttons are only active if there are previous shifts to restart/cancel or a shift is currently running.
