Start, lap, and reset. Lap times are kept in a list for the whole session, with the split and the running total for each.
This is a straightforward elapsed-time stopwatch, ticking to the hundredth of a second, running entirely within this browser tab — press start, and the timer counts up continuously until you stop or reset it.
The lap feature records two figures each time you tap it: the split (time elapsed since the previous lap) and the total elapsed time since the stopwatch started — useful for tracking pace across intervals during a workout, a race, or any timed activity with multiple stages.
Nothing is saved once you leave or refresh the page — this is a simple, ephemeral timer for the moment you're using it, not a workout log or a tool that tracks history across sessions. If you need to keep a record, note down your lap times as you go.
The split is how much time passed since your previous lap (that interval alone). The total is the full elapsed time since you started the stopwatch. Both are recorded together each time you tap lap.
It continues running in the background as long as the tab stays open, since the timer is based on actual elapsed time rather than something that pauses when the tab isn't visible.
No practical limit is imposed by the tool itself — record as many laps as your activity needs.
No — this is a simple, in-the-moment stopwatch with no history or account system. Note down any times you want to keep before closing or refreshing.
