Timer
A countdown timer with hours, minutes, and seconds. Switch to Pomodoro mode for automatic 25-min work / 5-min break cycles. An audio beep and screen flash alert you when time is up.
What Is an Online Timer
This timer is a browser-based tool that counts down from a time you set and alerts you the moment it reaches zero. There's nothing to install and no account to create — just open the page, pick a preset, and the countdown begins. One-tap presets are available for 1, 3, 5, 10, 15, 20, 25, 30, and 60 minutes, and any other length can be entered directly using the hours, minutes, and seconds fields.
The remaining time is shown both as digits and as a circular ring, so you can check your progress at a glance even from across the room. When the countdown ends, an audio beep and a flashing screen let you know, and a "+1 min" button lets you extend the session on the spot without resetting everything. All the counting happens locally in your browser — the time you enter is never sent to a server.
How to Use the Timer
- Choose a duration Tap a preset like "3 min" or "5 min", or type numbers directly into the hours, minutes, and seconds fields.
- Press Start The countdown begins immediately, with the remaining time shown as both digits and a ring.
- Pause or reset as needed Use "Pause" to stop and "Resume" to pick up where you left off, or "Reset" to return to your original setting.
- Get notified when time is up A beep sounds and the screen flashes at zero. If you need a little longer, tap "+1 min" to keep going.
Tips for getting more out of it
- The Pomodoro Technique uses 25 minutes of focus followed by a 5-minute break. Switch to Pomodoro mode and it manages the cycle automatically.
- After time's up, press "+1 min" to extend the countdown — handy when you need just a bit more time.
- Toggle the sound alert with the button below the timer. If no sound plays, check your device and browser volume settings.
- The timer keeps running in background tabs, but some browsers may reduce accuracy in power-saving mode.
- Closing or reloading the page resets the timer. Keep the tab open during long sessions.
When This Timer Comes in Handy
Cooking and kitchen tasks
Three minutes for instant noodles, a set time for boiling pasta, ten minutes for steaming rice — a single tap starts the countdown even when your hands are full.
Focused study or work sessions
Practice the Pomodoro Technique of 25 minutes of focus followed by a 5-minute break. Switch to Pomodoro mode and the app automatically manages the work/break cycle and set count for you.
Exercise and training intervals
Great for interval workouts like 30 seconds on, 30 seconds off, or for timing static holds such as planks.
Presentations and meeting time limits
Keep speaking slots and meeting agenda items on track. Share your screen and everyone in the room can see the time remaining.
Timer Terms Explained
- Countdown timer
- A timer that counts down from a set duration to zero, the opposite of a stopwatch, which counts up from zero.
- Pomodoro Technique
- A time-management method built around repeating cycles of 25 minutes of work followed by a 5-minute break, with a longer break of around 15 minutes after every four cycles.
- Interval timer
- A way of using the timer to alternate between fixed-length segments, such as exercise and rest, by restarting it for each new segment.
- Background throttling
- A browser behavior that reduces processing in hidden tabs to save power. Because this timer calculates the remaining time from its start timestamp rather than counting ticks, switching tabs never throws off the finish time.

Side Note — The Pomodoro Technique and the Story Behind Its 25-Minute Interval
The Pomodoro Technique was created in the late 1980s by Francesco Cirillo, then a university student in Italy. The name comes from the tomato-shaped (pomodoro) kitchen timer he used at the time. The method breaks work into 25-minute focused sessions ("pomodoros") separated by 5-minute breaks, cycling repeatedly to maintain concentration and boost productivity.
Why 25 minutes? Cirillo himself said he experimented with 10, 20, and 30 minutes before settling on 25 as the best balance between focus and rest. Research suggests that humans can sustain peak concentration for limited periods — some studies cite 90 minutes as the upper limit — and that breaking work into smaller chunks increases motivation through frequent small wins.
Today countless Pomodoro apps exist, yet the technique's core appeal remains its simplicity: all you need is a timer. Recent studies consistently show that single-tasking outperforms multitasking in both quality and speed, and the Pomodoro Technique remains one of the most practical frameworks for putting that principle into daily practice.
