FAQ

How accurate is the stopwatch?

The stopwatch uses JavaScript’s Date.now() for timing and displays millisecond precision. It’s accurate enough for most timing needs including workouts and productivity tracking. For scientific precision, use dedicated hardware.

Can I save my lap times?

Yes. Click the “Copy Laps” button to copy all recorded lap times to your clipboard. You can then paste them into a spreadsheet, notepad, or any text application.

Does the stopwatch keep running if I close the tab?

No. The stopwatch only runs while the page is open. Closing the tab or browser resets the timer. The stopwatch does not use server-side timing.

What’s the difference between split time and lap time?

Split time is the total elapsed time since the stopwatch started. Lap time is the duration since your last lap was recorded. For example, in a running workout, split time tells you your total run duration, while lap time tells you each individual mile split.

Can I use keyboard shortcuts?

Yes. Press Space to start or stop, press L to record a lap, and press R to reset. These shortcuts make it easy to use the stopwatch without touching your mouse.

Tips

• Use keyboard shortcuts for faster control during workouts — Space to Start/Stop, L for Lap
• Record a lap at the start to mark your baseline, then each lap tracks interval duration
• Copy laps to a spreadsheet after your session for detailed analysis of your performance over time
• Use the stopwatch alongside a timer for interval training — time your work periods and rest periods separately
