What is Stopwatch Timer?
This stopwatch runs locally in your browser. Click Start to begin, Stop to pause and again to resume, Lap to log the current elapsed time into the lap list, and Reset to clear everything. The lap list records each lap in order. Accuracy depends on the browser's built-in timer, which is fine for everyday timing. All state lives in the current page — refreshing clears it, and nothing is uploaded. Great for sports training, cooking, meeting speaking limits, exam simulations, and focused work sessions.

What is a stopwatch timer?
An online timing tool. Input: start, pause, lap, and reset actions. Output: elapsed time and a lap list. Used for sports, cooking, and work timing. Runs locally in your browser.
How do I record laps?
While timing, click Lap and the current elapsed time is appended to the lap list in order.
How do I resume after pausing?
Click the Stop button again — timing resumes without resetting the accumulated time.
How accurate is it?
It uses the browser's built-in timer, which is plenty for daily use; use professional equipment for millisecond-critical timing.
Does the timer survive a refresh?
No. All state lives in the current page; refreshing or closing clears it.
Does it keep running in the background?
Browsers throttle timers in background tabs, so keep the page in the foreground for accurate timing.
Does it need a network connection?
Once loaded, it works offline — timing requires no network.
