FAQ
- How accurate is the online stopwatch?
- Time is measured by the browser's system clock to the millisecond, not by counting frames. Even if the tab goes to the background, the stopwatch shows the correct time when you return.
- Does the stopwatch keep running if I close the tab?
- The start moment is saved in the browser. If you accidentally close the page and open it again, the stopwatch resumes from the same moment.
- Where does my data go?
- Nowhere. The tool runs entirely in your browser: the page loads once, then everything is calculated on your device. You can go offline and it keeps working.
- Is it free and without registration?
- Yes. No accounts, no limits and no watermarks on the result.
