About this tool
A stopwatch is the right tool when you need to measure elapsed time rather than count down to zero. Athletes, facilitators, and engineers use stopwatches to capture splits, compare attempts, and keep meetings within budget.
Unlike a wall clock, a digital stopwatch with lap memory lets you record multiple segments in one session. That makes it easier to analyze performance trends or document how long each phase of a process actually takes.
Running the stopwatch in the browser keeps your workflow lightweight: no install step, and you can reset or copy results when you are done. Lap data can be exported for notes, spreadsheets, or training logs.
Using this stopwatch
Press Start to run, Lap for splits, and Export laps to copy results to your clipboard for spreadsheets or notes.
