Keep This Tab Visible but Muted: The timer needs to run in a foreground tab. Browsers throttle background tabs, so the alert might not fire on time if you switch away. Keep the tab open in its own window.
Customize Durations to Your Rhythm: The default 25/5 works for most, but some people do better with 50/10 or even 90/20. Experiment and find what keeps you in flow without burning out.
Protect the Break Time: The 5-minute break isn't optional — it's when your brain consolidates what you just worked on. Stand up, stretch, look away from the screen. Don't cheat the break.

What Is a Pomodoro Timer?
A Pomodoro timer is a productivity tool based on the Pomodoro Technique, a time management method developed by Francesco Cirillo in the late 1980s. The name comes from the tomato-shaped kitchen timer (pomodoro in Italian) that Cirillo originally used as a university student. The core idea is simple: break your work into short, focused intervals (traditionally 25 minutes) separated by brief breaks. Each interval is called a pomodoro. After completing four pomodoros, you take a longer break of 15–30 minutes. This structured alternation between focus and rest helps sustain concentration, reduces mental fatigue, and makes large tasks feel more approachable. Our timer runs entirely in the browser — no sign-up, no downloads, no data sent to any server.
How to Use
Choose your mode at the top — Work (25-minute focus session), Short Break (5 minutes), or Long Break (15 minutes after four sessions). Click Start to begin the countdown. When the timer buzzes, take your break and then start the next session. Adjust all durations in the settings panel to match your personal rhythm.

Pro Tips for Pomodoro Success
The Pomodoro Technique works because it breaks large tasks into manageable sprints, lowering the mental barrier to starting. The forced breaks prevent decision fatigue and keep your brain fresh across long work sessions. The ticking clock also creates gentle accountability — knowing a break is coming in 25 minutes makes it easier to resist distractions now.
Frequently Asked Questions
What is the Pomodoro Technique?
A time management method: work 25 minutes, break 5 minutes. Repeat 4 times, then take a 15-30 minute break.
Can I customize the timer?
Yes, adjust work, short break, and long break durations in the settings below the timer.
Why keep the timer tab open?
Browsers throttle JavaScript in background tabs, which can delay the countdown and alert sound. Keep the tab in a visible window for accurate timing.
Does this Pomodoro timer work offline?
Yes. The entire timer runs in your browser with no server calls. Once the page is loaded, it works without an internet connection.
How many sessions should I do per day?
Most people find 8-10 sessions (4-5 hours of focused work) to be a good daily target. Start with 4 sessions per day and gradually increase as your focus improves. Quality matters more than quantity.
What if I get interrupted during a session?
If you're interrupted, pause the timer or let the session complete naturally. The goal is focused work — if you can't focus, it's better to reset and start fresh than to push through distractions.
Can I use this for studying or exercise?
Absolutely. The Pomodoro technique works for any focused activity: studying, writing, coding, exercise, or language practice. Just set your work duration to match your task.
Pomodoro Variations
There are many ways to adapt the Pomodoro technique to your needs:
52/17 Method: Work for 52 minutes, break for 17 minutes — for deep work sessions.

Tips for Maximum Productivity:
Start small: If 25 minutes feels too long, begin with 15-minute work sessions and gradually increase.
Single task focus: Resist the urge to check emails or messages during work sessions — that's what breaks are for.
Prepare your break: Before starting a session, decide what you'll do during the break (stretch, water, quick walk).
Track your patterns: Note when you're most focused and schedule demanding work then.
End on a high note: Stop mid-task when the alarm sounds — you'll know exactly where to continue next time.
Weekly review: At the end of each week, assess your productivity and adjust durations accordingly.
