A 'Timebar' is a bar that fills as time passes - a reminder of the limited nature of time.
Simply set a start and finish date, and it'll show the percentage of time passed.
Create a timebar to become aware of how much of the day has gone by.
Or how much of the week has gone by.
Or the month, or the year.
Or even...how much of your estimated life span has gone by!
The widget helps you develop a long-term awareness of time, because your timebars are right there on the home screen.
Become more aware of how you choose to spend your time. It's 'mortality motivation'.
