A stopwatch and timer that just work
No app to install, no permissions to grant — open the page and start timing. The stopwatch counts up for whenever you need to measure how long something takes; the countdown timer counts down to zero and alerts you when time's up. Switch between the two with a tap.
Handy for everyday timing
It's the quiet workhorse of a productivity routine: timing focused work sprints, keeping presentations to length, managing rest between gym sets, steeping tea, or running a quick experiment. Because it lives in a browser tab, it's always a click away on whatever device you're already using.
Frequently Asked Questions
Does this timer work when I switch tabs?
Yes. The timer continues running in the background even when you switch to another browser tab. However, some browsers may throttle background JavaScript after a period of inactivity. For critical timing, keep this tab active or use your phone's native timer app.
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method where you work for 25 minutes, then take a 5-minute break. After four such "pomodoros," you take a longer break of 15–30 minutes. Use the countdown timer to implement this technique — set 25 minutes for work and 5 minutes for breaks.
Can I use this stopwatch for sports timing?
Yes. The stopwatch measures time to millisecond precision and supports lap recording, making it suitable for timing running sprints, swimming lengths, or cycling segments. For official competitive sports events, a certified stopwatch or timing system should be used.
