Countdown Timer & Stopwatch (Alarm, Interval, Pomodoro)
Dial in the exact hours, minutes, and seconds you need. Start, pause, reset, and reuse presets all in one interface.
Set shareable countdowns for launches, workouts, or study blocks.
Use a browser-based countdown timer for Pomodoro sessions, workouts, cooking, study blocks, meetings, or classroom pacing. Start, pause, reset, and reuse presets without installing an app or creating an account.

What This Timer Is Best For
This page is meant for single-person countdowns that need to start immediately and stay visible. It works well for Pomodoro sessions, study blocks, meetings, workouts, cooking, interview practice, classroom pacing, and short breaks between focused tasks.
If you need a public event countdown that lasts for days, a shared team timer, or reminders that still fire after you close the tab, use a calendar or dedicated event app instead. This tool is intentionally simple: set a duration, press start, and keep the timer open while you work.
Recommended Presets for Real Work
| Use case | Starting point | Why |
|---|---|---|
| Pomodoro focus block | 25 minutes | Balanced for concentration without too much resistance |
| Admin cleanup | 15 minutes | Good for email, review, and quick batching |
| Deep work sprint | 45 minutes | Better when context switching is expensive |
| Workout round | 30 seconds to 5 minutes | Easy to reuse for interval work |
| Short break | 5 minutes | Prevents breaks from drifting too long |
| Timed meeting segment | 10 to 20 minutes | Keeps discussions moving |
How To Get Reliable Results
- Set the timer to the real session length you plan to finish, not an idealized one.
- Keep the tab open and visible when possible, especially if the session matters.
- Test a short timer first if you are relying on the completion state for a class, meeting, or workout.
- If you are presenting or using a shared screen, pair this with Keep Screen On so the display does not dim halfway through.
Good Ways To Use It
- Put it on a second monitor during meetings so everyone can see the remaining time.
- Use 15-minute starts when you are procrastinating; short starts lower the friction of beginning.
- Run repeated 25/5 or 45/10 cycles for study, coding, and writing.
- Keep it visible during cooking or lab work instead of relying on a phone that may lock or distract you.
What This Tool Does Not Try To Do
- It does not sync across devices or team members.
- It does not replace a calendar or reminder app.
- It does not guarantee audio playback if your computer is muted.
- It does not keep running after you close the tab.
Privacy and Review Notes
The timer runs locally in your browser. There is no account, no saved schedule on our server, and no upload step because there is nothing to upload. This page is maintained as a practical workflow page rather than a thin landing page, so browser limitations and common timer setups are documented alongside the tool itself.
Key features
- Focus-Friendly Visuals: A large, clean progress ring allows you to check remaining time with a quick glance, minimizing cognitive load while you work.
- Background-Aware Accuracy: Uses robust time-syncing logic to ensure the timer stays accurate even if you switch tabs or your browser throttles background activity.
- Pomodoro & HIIT Presets: One-tap access to 25-minute focus blocks or custom intervals for High-Intensity Interval Training (HIIT).
Frequently asked questions
Will the alarm sound if my computer is muted?
No, you must have your system sound on. We recommend testing the volume with a short 5-second timer first.
Can I use this for presentations?
Yes! The clean interface looks great on projectors, and the "Keep Screen On" feature (compatible with most browsers) prevents the display from dimming.
Does the timer keep running if I switch tabs?
Yes. The countdown uses JavaScript intervals that continue as long as the tab stays open. If the browser throttles background tabs, the timer syncs itself as soon as you return.
Can I reuse my favorite durations?
Use the quick presets (5, 15, 25, 45 minutes) or set a custom duration and hit start. The previous values stay in place until you adjust them again.
Will it make a sound when finished?
When the remaining time reaches zero the interface highlights the completion message. You can keep the tab open to stay notified or pair it with your own audio cue.

Pomodoro vs. Deep Work: How a Simple Countdown Timer Boosts Productivity
People usually frame productivity as a tool problem. In practice it is more often a structure problem.

They are just two different ways of timeboxing attention. Pomodoro: Short Cycles With Clear Recovery Pomodoro is best when you need help…
