Count up, with laps
Good for intervals, presentations, exam practice and anything where you need splits rather than a countdown. If you want the opposite direction, use the countdown timer.
Common questions
How accurate is it?
It reads the system clock rather than counting animation frames, so elapsed time is accurate to the hundredth of a second and does not drift if the tab is throttled.
What does the lap button do?
It records a split without stopping the main count. Each lap shows both the time since the previous lap and the total elapsed, newest at the top.
