?Frequently Asked Questions

How accurate is this online stopwatch?

This stopwatch uses your browser's high-resolution performance API, making it precise to the millisecond. However, accuracy can be slightly affected by your device's processing speed.

Can I use the stopwatch offline?

Yes! Once this page is loaded, the stopwatch functions entirely locally on your device using JavaScript. You don't need an active internet connection to keep timing.

Does it work in the background?

Most modern browsers will throttle inactive tabs to save battery. For long-term timing, we recommend keeping this tab active or in its own window to ensure the highest accuracy.

How do I save my lap times?

After recording laps, click the 'Export CSV' button to download a spreadsheet file compatible with Microsoft Excel and Google Sheets, or 'Export JSON' for raw data.
