Frequently Asked Questions About Stopwatch Usage

How accurate is the online stopwatch?

Our digital stopwatch uses your browser's high-resolution time API, which typically provides accuracy within milliseconds. The actual precision may vary slightly depending on your device's hardware and current system load, but for most practical applications, the timing is sufficiently accurate.

Can I use the stopwatch without an internet connection?

Yes, once the page is loaded, our online stopwatch works completely offline. The timing functionality is handled locally by your browser, so no internet connection is required during use. This makes it reliable even in areas with poor or no connectivity.

How do the voice alerts work?

The voice alerts use the Web Speech API available in modern browsers. When enabled, the stopwatch will announce start, stop, and lap events using synthetic speech. You can customize the voice type and which events trigger alerts according to your preferences.

Can I save my lap times for later analysis?

Yes, our stopwatch with lap timing includes an export feature that allows you to download all lap times as a CSV file. This file can be opened in spreadsheet applications like Excel or Google Sheets for further analysis and record-keeping.

Is there a limit to how many laps I can record?

There is no practical limit to the number of laps you can record. The stopwatch will continue adding lap times until you reset the session. However, extremely high numbers of laps may affect performance on older devices.
