UTL
Stopwatch
Start, pause and record laps — split and total time are tracked for each lap.
00:00.00
How it works
Timing uses the system clock rather than counting display updates, so pausing and resuming stays accurate even if the tab is backgrounded for a moment. "Split" is the time for that lap alone; "Total" is the running time since Start.
Frequently asked
Does the stopwatch keep running if I switch tabs?
Yes — it tracks real elapsed time from the system clock, not from counting screen updates, so the time stays accurate even if the browser throttles the tab in the background.
Is there a limit to how many laps I can record?
No practical limit — laps are kept for the current session until you reset.
