Frequently asked questions
- Does the counter continue if I leave the tab?
- Yes, time keeps counting even with the tab in the background. When you return, the displayed value is up to date. Note: some browsers may reduce timer precision in background tabs, but total time stays correct.
- Can I run stopwatch and timer simultaneously?
- Not in this version. The tool has a single active mode at a time. If you need to time multiple things in parallel, open several tabs or use a dedicated app with multiple timers.
- What are laps?
- Intermediate time markers within a continuous stopwatch. Useful for recording times of each lap on a track, intervals between sets in an exercise, or milestones during a process. The stopwatch keeps running, and each lap is recorded with total time and time since the previous lap.
