openpomodoro is a free, customizable Pomodoro timer that works on any desktop or mobile browser — no sign-up required. It helps you stay focused on any task: studying, writing, coding, or deep work. Built around the Pomodoro Technique, a time management method developed by Francesco Cirillo, openpomodoro breaks your work into 25-minute focus sessions followed by short breaks so you stay sharp without burning out.
The Pomodoro Technique turns intimidating projects into a rhythm of short, winnable sprints. Here's the loop:
Decide what you'll work on before you start. One task, one timer — that's the whole trick.
Press start and work with full attention until the timer rings. No tabs, no feeds, no “quick checks.”
Step away from the screen. Stretch, grab water, look out a window — let your brain breathe.
After four Pomodoros, reward yourself with a longer 15–30 minute break before the next cycle.
A timer should help you focus, not become another app to manage. Every feature here earns its place.
Classic 25/5 doesn't fit everyone. Switch to 45/15 for slow warm-ups, 50/10 for deep coding sessions, or anything in between — work, short break, and long break are all adjustable in settings.
Pick your alarm, add optional ticking for urgency, and tune the volume of each.
Chain Pomodoros and breaks automatically so the rhythm carries you — no clicking between rounds.
Open the page, press start. No account, no paywall, no trial that expires mid-sprint.
Desktop, tablet, or phone — if it has a browser, it has a Pomodoro timer.
Every completed Pomodoro bumps your round count, so you always know how deep into the cycle you are.
The countdown lives in your tab title, so you can see time left from anywhere. Go fullscreen to hide everything else, and control the timer with Space — start and pause without touching the mouse.
The technique was created by a developer, entrepreneur, and author Francesco Cirillo. He noticed that when faced with large tasks or a series of assignments, we're able to be most effective if we break the work down into short, timed intervals (called "Pomodoros") which are spaced out by short breaks.
In essence, it is a cyclical system based around working in short bursts of 25 minutes with intermittent breaks, of 5 minutes, which can help to improve motivation, creativity and efficiency.

I used the Pomodoro Technique as a student to push through long study sessions. My problem: I only warm up after 20–30 minutes— exactly when the classic version tells you to stop. If that's you too, switch the 25/5 intervals to something like 45/15: work for 45 minutes, then take a proper 15-minute break. This timer lets you set whatever rhythm fits your brain.
