A stopwatch with lap times, a countdown timer, and a Pomodoro cycle with work and break intervals.

Tips
- The stopwatch measures elapsed time from a high-resolution clock, so it stays accurate even if the tab is throttled in the background.
- Lap times record the split since the previous lap alongside the total, which is what you want for intervals.
- The Pomodoro cycle defaults to 25 minutes of work and 5 of break, with a longer break every fourth cycle.
- Browsers block sound until you interact with the page, so press start at least once before relying on the alert.
Frequently asked questions
Is it accurate if I switch tabs?
Yes. Elapsed time is computed from timestamps rather than counted tick by tick, so throttling affects how often the display refreshes but not the measurement.
