What this online stopwatch does
This online stopwatch times anything directly in the page, with start, pause, lap, and reset controls. Start it when an activity begins, record lap times to capture splits without stopping the clock, and pause or reset when you finish. It needs no app or account, which makes it handy for workouts, cooking checks, practice sessions, classroom activities, and quick timing jobs at a desk.
When lap times are useful
Laps let one timing session hold several results: interval training, repeated attempts at a task, or each stage of a process timed separately. Pressing Lap saves the current split while the main clock keeps running, so you can compare segments afterwards instead of restarting the stopwatch for every attempt and losing the overall time.
Good to know
Timing uses your device clock and runs in this page; closing the page pauses the session, and the stopwatch is not a certified timekeeping device. For everyday timing it is dependable, but official or competition results should come from dedicated timing equipment.
Frequently asked questions
How do lap times work?
Press Lap while the stopwatch runs and it records the current split in a list, while the main timer keeps going. Record several laps in one session and compare them afterwards.
What happens if I close the page?
The timing pauses when the page closes, because the stopwatch runs in the page itself. Keep the page open for an unbroken session, and use Reset to start over.
How accurate is this stopwatch?
It follows your device clock, which is accurate enough for training, cooking, and everyday tasks. It is not certified equipment, so avoid it where results have official consequences.
