Track elapsed time with lap tracking.
This stopwatch tracks elapsed time from the moment you press Start, with a Lap button to record split times without stopping the clock — useful for tracking intervals in a run, a workout circuit, or timing repeated steps in a process.
Each lap shows both the split time (time since the previous lap) and the total elapsed time, so you can see pacing across a session, not just a single final number.
Like the Timer, this runs entirely in your browser tab and keeps counting as long as the tab stays open, including in the background.
A timer counts down from a set duration to zero; a stopwatch counts up from zero indefinitely until you stop it, with no preset end.
Each lap records the split time since the previous lap and the total elapsed time, useful for tracking pace across intervals.
No practical limit — it will keep counting as long as the browser tab remains open.
