What is the difference between a lap and a split?
A split is the time of one section, measured from the previous lap. The total is the time since you pressed Start. If you run four laps of 60, 58, 61 and 59 seconds, the splits are those numbers and the totals are 60, 118, 179 and 238 seconds.

Use it to time laps on a track, sets at the gym, a speed run or a presentation. The display updates every frame and uses the browser’s high-resolution clock, so it stays smooth. For a countdown instead, try the online timer.
Frequently asked questions
How accurate is the online stopwatch?
It uses the browser’s high-resolution timer and shows hundredths of a second. Real-world accuracy is limited by your screen refresh and how fast you press the button, typically within a few hundredths.
Does it keep running if I switch tabs?
Yes. It measures real elapsed time, so the number is correct when you come back, even if the tab was in the background.
How do I record a lap?
Press the Lap button or the L key while the stopwatch runs. Each lap shows its own split time and the total time so far.
Can I save my lap times?
Press Copy laps and paste them into a note or a spreadsheet. The page does not store them, so they are gone when you close it.
