How to use
- Stopwatch: press Start to time to 1/100 second; press Lap to record splits.
- Timer: enter hours, minutes and seconds, or tap a preset like 5 or 25 minutes, then press Start.
- When the timer ends, an alarm plays and the tab title flashes, even if you’re on another tab.
Good to know
Timing uses your browser’s high-resolution clock, so it stays accurate even if you switch tabs.
The Pomodoro technique alternates 25 minutes of focus with 5-minute breaks — tap the 25 min preset to start.
On phones, sounds may be delayed or blocked when the screen turns off. Keep the screen on for important alarms.
FAQ
Does it keep running in another tab?
Yes. Time is measured from real elapsed time, and the tab title shows when the timer is done.
I can’t hear the alarm.
Browsers only play sound after you interact with the page. Make sure you pressed Start yourself and your device isn’t muted.
Are there keyboard shortcuts?
In the stopwatch: Space to start/stop, L for lap, R to reset.
