This Online Timer is three tools in one: a countdown timer, a stopwatch, and a Pomodoro timer. Switch between them with the tabs at the top. Set a countdown with the hour/minute/second fields or a one-tap preset, time an activity with the stopwatch and record laps, or run focused work sessions with the Pomodoro mode.
It runs entirely in your browser — no sign-up, no ads interrupting the count — and sounds an alarm when the countdown or a Pomodoro phase ends. The timing is anchored to the real clock, so it stays accurate even if the tab is in the background.
How to use the online timer
- Pick a mode: Timer, Stopwatch, or Pomodoro.
- For the timer, enter hours, minutes, and seconds, or tap a preset like 5 or 25 minutes.
- Press Start to begin, Pause to hold, and Reset to clear.
- For the stopwatch, use Lap to record split times; for Pomodoro, set your focus and break lengths and the number of rounds.
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method that breaks work into focused intervals separated by short breaks. You work for a set period — classically 25 minutes — then take a 5-minute break; after a few rounds you take a longer break. It helps sustain concentration and avoid burnout.
This timer runs the full cycle for you: it counts down each focus and break period, sounds an alarm at each switch, and automatically moves to the next phase, tracking which round you are on.
A classic Pomodoro cycle (all lengths are configurable here).
| Phase | Length | When |
|---|---|---|
| Focus | 25 min | Each work session |
| Short break | 5 min | After each focus session |
| Long break | 15–30 min | After every 4 focus sessions |
Timer, stopwatch, or Pomodoro — which to use
- Timer: counts down from a set time — for cooking, workouts, exams, or any fixed-length task.
- Stopwatch: counts up from zero and records laps — for timing how long something takes.
- Pomodoro: alternates focus and break periods — for studying and deep work.
- The alarm and timing keep working while the tab is in the background, so you can switch away and still be alerted.
Frequently Asked Questions
Does the timer keep running if I switch tabs?
Yes. The countdown is anchored to the real clock rather than counting ticks, so it stays accurate in a background tab, and the alarm sounds when time is up. Some browsers throttle background audio, so keep the tab open if you rely on the sound.
What is the Pomodoro Technique?
It is a focus method of working in timed intervals — typically 25 minutes of focus followed by a 5-minute break, with a longer break after four rounds. This tool runs the whole cycle and switches phases automatically.
Can I change the Pomodoro focus and break lengths?
Yes. In Pomodoro mode you can set the focus length, short break, long break, and the number of rounds before a long break. The classic settings are 25 / 5 / 15 over 4 rounds.
Is there an alarm sound?
Yes, the timer plays a tone when a countdown finishes or a Pomodoro phase ends. It uses your browser’s audio, so make sure the tab is not muted.
Does it work offline and is it private?
Everything runs in your browser with no sign-up, and nothing you set is sent anywhere. Once the page has loaded it keeps working without a connection.
