What Stopwatch does

Users can enter a name for their stopwatch and click Start to begin timing; pressing Stop displays the total duration in hours, minutes, seconds, and milliseconds.

Stopwatch FAQ
- Can I use the stopwatch on a mobile device?
- Yes, but if the phone keeps the address bar visible, rotating to landscape mode is required for fullscreen display, which is a browser limitation rather than a tool fault.
- Does the stopwatch keep time if I switch to another tab?
- No, the overlay counts elapsed wall-clock time only while the current tab is active; switching tabs pauses the timer.
- Is there a way to add a delay before the stopwatch starts?
- Yes, the site offers an optional start delay of 5 or 10 seconds if you need time to put the laptop down or face the room before timing begins.
- What happens if I accidentally close the tab?
- Closing the tab ends the stopwatch entirely; the timer does not persist outside the browser session.
