The time is worked out from the moment you pressed Start, not added up tick by tick, so it never drifts, even over hours.
Switch tabs, lock the screen or let the computer sleep: when you come back the stopwatch shows the right time.
A running stopwatch and its laps are saved in your browser. Close the tab by mistake and it is still running when you return.
Each lap shows its lap time and the total. The fastest lap is marked green, the slowest orange, with the average underneath.
Show the time across the whole screen for a class, a workout or a stage.
Download the laps as CSV with times in both minutes:seconds and milliseconds, or copy them as a table.
Space starts and stops, L records a lap, R resets and F switches to full screen.
Press Lap at the end of each run, round or rep to compare them side by side.
Leave it running: it keeps counting for hours, through sleep and reloads.
Use the online timer to count down from a set time with an alarm.
