Stopwatch and timer
A precise stopwatch with lap times and a countdown timer with an alarm sound, in your browser.
Private by design: everything is processed on your device. Nothing you add is uploaded or stored.
How to use it
- Choose Stopwatch or Timer.
- Start, pause, add laps or set the time.
- Keep the tab open; the timer rings when it ends.
Questions
Does it keep running if I switch tabs?
Yes. Times are measured from the clock, not by counting ticks.
