Stopwatch
Simple online stopwatch with lap timing, pause, and reset functionality.
About Stopwatch
Built with athletes, cooks and anyone timing an activity in mind, the Stopwatch keeps every input and every result on one clean page. Time any activity with millisecond accuracy, using start, stop, lap and reset controls, with each lap time recorded so you can review splits. The stopwatch keeps running in a background tab, which matters for long tasks, and it shows both the elapsed and the lap time clearly. Athletes use it for runs, cooks for proofs and bakes, and students for timed practice, and the lap feature is what sets it above a phone clock. Because it is a pure browser tool, it works offline and never uploads anything. A large, readable display suits use at a distance, and the controls stay finger-friendly on a phone. It is the no-frills timer that always starts instantly. Dates follow the DD/MM/YYYY convention used across India, and timezone behaviour matches how calendars and salary cycles actually run here. Common scenarios include timing a run with lap splits, timing a proof or bake, and timing a practice test section. Bookmark it once and it is ready whenever the need comes up again.

Lap time records the duration of each completed lap/segment. Split time shows the cumulative time from the start. Both are useful for fitness and performance tracking.
Can I use stopwatch in background?
The stopwatch continues running even if you switch tabs, but browser timer throttling may reduce accuracy after several minutes in background tabs.
Does the stopwatch keep running in another tab?

What are lap times for?
Laps record the time at each point you press, so you can review splits for each segment of a run or task.
