Time an activity and keep lap splits

A stopwatch is only half the job — the lap table is what tells you which stretch was slow.

Tools used in this guide

The job

Interviews, workouts, cooking stages, exam sections — anything where the total is less useful than the breakdown. Start the stopwatch and press lap at each boundary.

Using laps

Each lap records the split since the previous lap and the total so far. Scanning the split column tells you where time went; the total column is a sanity check against the clock.

The display keeps counting real elapsed time even if the browser throttles a hidden tab, so you can switch away mid-measurement.

Limits

Precision is hundredths of a second — fine for human activities, not a laboratory instrument. Laps are kept only while the page is open; they are not saved, so copy them out if you need them later.
