Timers & productivity
Pick a length and the countdown fills the screen, rings a loud alarm at zero, and keeps perfect time even in a background tab. 13 common lengths from one minute to two hours, each on its own page with a one-tap start and a deep-linkable autostart URL.
A timer is the simplest productivity tool there is, and also the most underrated. Putting a finite, visible boundary around a task changes how you approach it: a five-minute break stops sprawling into twenty, a dreaded chore becomes a survivable ten-minute sprint, and a vague afternoon of “working on the report” turns into three concrete twenty-five minute rounds. The countdowns below are built for exactly that. Each one is a full-screen, single-purpose timer with a clear digital readout, a progress ring, and an alarm you cannot miss, with nothing else competing for your attention.
Every timer here is anchored to a fixed end time rather than counting ticks, so it stays accurate when you switch tabs or your phone sleeps — a real problem with naive browser timers, which the operating system throttles in the background. Pick a length to open its page, where you will also find a short, practical note on what that exact duration is best suited to, from the two-minute rule to the ninety-minute ultradian work cycle.
These timers count down a set length. If you want a different shape of timer, the Pomodoro timer automatically loops work and break intervals and tracks your sessions, the online stopwatch counts up from zero with lap times, the alarm clock rings at a specific time of day rather than after a duration, and the countdown maker counts down to a future date and can be shared or embedded on your own site.
Yes, completely. There is no sign-up, no app to install, and no limit on how many times you can use it. Pick a length, press start, and it counts down with an alarm at the end.
Yes. Each timer is anchored to a fixed end time the moment you start it, so the remaining time is recomputed from your device clock whenever you return — it does not drift the way tick-counting timers do in throttled background tabs. Keep the page open so the alarm can sound, and on mobile the page requests a screen wake lock so the display does not sleep.
A short series of rising chimes, repeated, generated in your browser with the Web Audio API. Because it is synthesised rather than loaded from a file, it is ready instantly and works offline. Raise your device volume for a louder alert.
Yes. Add ?autostart=1 to any timer URL — for example /timer/5-minutes?autostart=1 — and the countdown begins the moment the page loads. Bookmark the ones you use most so a single click starts them.
For short breaks, 5 minutes is the classic choice; for focused work, 25 minutes is the Pomodoro interval; for a power nap, 15 to 20 minutes avoids grogginess; for deep work, 45 or 90 minutes match natural attention cycles. Each timer page explains what its length is best for.
