What is Countdown Timer?
Countdown Timer runs a simple in-browser timer with start, pause, reset and an audible alert when it finishes. No accounts, no installs — just open the page and set the duration. Useful for focus sessions, recipe steps, workout intervals, or any short fixed duration where you want hands-off notification.
Why use this tool?
- Touch-friendly UI, fine on phones for on-the-go edits
- No registration, account, or installation required
- No API keys to manage and no rate limits to monitor
- No upsell to a paid plan: every feature is free forever
- Designed for everyday quick tasks — open the page, get the answer, move on
How to use
- Enter hours, minutes, and seconds — or pick a quick preset (5min, 25min Pomodoro, 1h)
- Click Start to begin counting down
- Pause/resume as needed — Reset clears back to the original duration
- An audible alert plays when the timer hits zero
Examples
Pomodoro focus block
Set 25:00, click Start, mute notifications elsewhere, and let the timer ping you when the block ends.
Recipe step
Cooking pasta for 8 minutes? Set 8:00 and walk away — when the alert plays, drain the pot.
Time-boxed meeting
Project the timer in a stand-up to keep updates to 2 minutes each. The visible countdown nudges people to wrap.
Common use cases
- Pomodoro and time-boxed focus sessions
- Cooking and recipe step timers
- Workout intervals (HIIT, Tabata)
- Time-boxed meeting segments and presentations
Troubleshooting
- No sound when timer ends.
- Most browsers block audio until you've interacted with the page. Click anywhere on the page first, then start the timer.
- Timer pauses when tab is hidden.
- Browsers throttle background tabs. Keep the tab visible, or use a dedicated OS-level timer for long durations where exact second-counting matters.
