Shortcuts: Space = start/pause · R or Esc = reset
The Countdown Timer counts down from a time you set to zero, then alerts you with a sound. Enter hours, minutes, and seconds, or tap a preset, and hit Start. You can pause and resume, reset at any time, and the display flashes when time is up so you don't miss it even with the sound off.
It's built for time-boxing — focused work sessions, breaks, cooking, workouts, study blocks, or any deadline where you want a clear "stop" signal. There's nothing to install and no account, and it works on phone, tablet, or desktop.
One practical note: the timer runs in your browser tab, so keep the tab open while it counts. If your device silences background tabs, the alert may be delayed until you return — for anything critical, keep the tab visible.
Set your time
Type hours, minutes, and seconds, or tap a preset like Pomodoro (25 min).
Press Start
The countdown begins; the display pulses in the final seconds.
Pause or reset anytime
Pause to hold the remaining time, or reset to start over. Space and R work as shortcuts.
Hear the alert
When it reaches zero, an audio alarm plays and the display flashes.
A popular way to use a countdown timer: alternate focused work with short breaks. Set the timer to each duration in turn.
| Session | Duration | Purpose |
|---|---|---|
| 🍅 Work | 25 minutes | Deep, focused work |
| ☕ Short break | 5 minutes | Rest and recharge |
| 🍅 Work | 25 minutes | Continue focused work |
| 🛋️ Long break | 15–30 minutes | After every 4 work sessions |
