Medium timers (10–45 minutes)
Press start for a full-screen 10-minute timer that counts down 10:00 and rings a loud alarm when it reaches zero. You can pause and resume it, reset it, and the countdown keeps running accurately even if you switch tabs or your screen dims. No sign-up, nothing to install.
Ready · 10-minute timer
Ten minutes is the sweet spot for a meaningful short task: a tidy-up that genuinely changes a room, a focused stretch of reading, a brisk walk, or a tightly-run meeting agenda item. It is also the length of a popular guided meditation and a common classroom activity block. Enough time to make real progress, not so much that the task expands to fill it.
The ten-minute rule is one of the most reliable anti-procrastination tools there is: commit to doing the dreaded task for just ten minutes, with full permission to stop when the timer rings. The trick works because resistance is almost entirely about starting. Once you are ten minutes in, the task no longer looks like an undifferentiated wall of effort — you can see its edges, you have momentum, and stopping now feels worse than continuing. More often than not you carry straight on past the chime. And on the days you do stop at ten minutes, you have still made ten minutes of progress on something you would otherwise have made zero on, which compounds faster than it sounds.
Most browser timers drift, because they count by accumulating small ticks, and browsers deliberately slow those ticks down in background tabs to save battery. This one is different: the moment you press start it records the exact wall-clock time the countdown should end, and every frame it simply measures how long is left until that fixed end time. If you switch tabs, lock your phone, or the tab is throttled, the remaining time is recomputed from the real clock the instant you come back, so a 10-minute timer is still a 10 minutes timer rather than however long the throttled ticks happened to add up to. On phones the page asks for a screen wake lock while the countdown is running, where the browser allows it, so the display does not sleep mid-count. The alarm is synthesised in the browser with the Web Audio API, which means there is no audio file to download and the chime is ready the moment you start.
