Most countdown apps only show what's left. Timesheet tools only count hours you logged. Track Time is a personal board of live clocks: time already gone and time still left, side by side.
A clock can be open-ended, upcoming, in progress, or over. Years and months follow the calendar, not a 30-day month. Hide a unit and the remainder rolls into the next one you kept. Mark work or personal, tag a family member, and email yourself at the start, the end, or days before.
