Frequently asked questions
Does it keep running when I switch tabs?
Yes. The time is calculated from the start time, not counted up. Even if the browser throttles the tab in the background, it is correct when you come back.
Is there a countdown timer too?
For focused work there is the Pomodoro timer, which counts down in fixed intervals.
