Free Online Pomodoro Timer — Focus Sessions, Breaks, Sound Alerts & Custom Durations
Start a Pomodoro session in one click. The circular ring counts down your 25-minute focus block, a gentle three-tone chime plays when time is up, and the timer switches automatically to a short break. No account, no app install, no subscription — just a clean, distraction-free focus timer in your browser.
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s. The method divides work into 25-minute focused intervals separated by short 5-minute breaks, with a longer 15-minute break after every four sessions. The technique works because it creates urgency (a countdown makes tasks feel finite), forces regular rest (preventing cognitive fatigue), and builds interruption awareness (you consciously defer distractions rather than react to them).
This timer follows the classic four-stage cycle. The round indicator shows four dots — one fills each time you complete a Pomodoro — so you always know where you are in the cycle. After the fourth Pomodoro, the long break triggers automatically. The tab title updates every second so you can monitor the countdown from any tab without switching back. Enable browser notifications to get a desktop alert when sessions end — even if the browser is in the background.
The task input above the timer lets you write what you're working on before you start. This is one of the key habits of the Pomodoro Technique: stating your intention explicitly before starting a session sharpens focus and gives you a record of how you spent your time. The daily stats panel tracks sessions completed, total minutes focused, and full cycles finished — giving you a satisfying summary of a productive day.
All durations are customizable in the settings panel. Common alternatives to the default 25/5/15 are 50/10/30 for deep work sessions, 45/10/20 for university study blocks, or 15/3/10 for short task bursts. Toggle auto-start to chain sessions automatically without clicking Play, and toggle sound alerts to control the chime. Everything runs offline once the page is loaded.

How to Use
Type what you are working on in the task input field above the timer — this sets your intention for the session. Click the red play button to start the 25-minute Pomodoro. The circular progress ring shrinks as time passes and the tab title shows the countdown so you can check it at a glance from another tab. When the session ends, a chime plays and the timer automatically switches to a short break. Work through four Pomodoros — the round dots track your progress — and the timer will trigger a 15-minute long break. Click the gear icon to customize session and break durations, toggle auto-start (so the next session begins automatically), toggle sound alerts, and enable browser notifications for desktop alerts. Use the skip button (▶|) to jump to the next session at any time. Use the reset button (↺) to restart the current session. Your daily stats (sessions, minutes, cycles) accumulate until you close or reload the page.

Frequently Asked Questions
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The method works in cycles: work for 25 minutes (one "Pomodoro"), then take a 5-minute short break. After completing four Pomodoros, take a longer break of 15–30 minutes. The name comes from the Italian word for tomato — Cirillo used a tomato-shaped kitchen timer when he developed the technique as a university student. The method is designed to reduce the impact of interruptions on focus, improve planning accuracy, and create a sustainable rhythm between work and rest.
Click the play button to start a 25-minute Pomodoro session. The circular ring counts down visually and the tab title shows the remaining time so you can see it at a glance without switching windows. When the session ends, a sound plays and the timer automatically moves to a short break. After four Pomodoros it switches to a long break. Type what you're working on in the task input above the timer — this keeps your intention clear and helps you stay focused. Use the settings gear to customize session and break durations, toggle sound alerts, enable auto-start, and enable browser notifications.
The default durations follow Cirillo's original specification: 25 minutes for a Pomodoro (focus session), 5 minutes for a short break, and 15 minutes for a long break (taken after every four Pomodoros). These defaults work well for most tasks. You can customize all three durations in the settings panel — common variations include 50/10/30 for deeper work sessions, 45/10/20 for university study blocks, or 15/3/10 for tasks that require shorter bursts of concentration.
Yes — the timer continues counting down when you switch to another browser tab or window. The browser tab title updates every second to show the remaining time (e.g., "23:47 — Pomodoro | WDP Tools"), so you can glance at your tab bar without switching back. If you enable browser notifications in the settings, you will also receive a desktop notification when the session ends, even if the browser is in the background. Note that some browsers throttle timers on inactive tabs for battery saving — the timer uses setInterval which is subject to this, but the discrepancy is typically under a second.
Yes — click the settings gear icon in the top-right corner to open the settings panel. You can set custom durations for the Pomodoro (1–99 minutes), short break (1–60 minutes), and long break (1–60 minutes). You can also toggle auto-start (automatically starts the next session when one ends) and sound alerts. Changes take effect immediately when you click Apply. The current session resets to the new duration. Your settings are applied for the current session — they reset to defaults if you reload the page.
The Pomodoro Technique improves focus through several mechanisms. First, it creates urgency: a 25-minute countdown makes the task feel finite and manageable, which reduces procrastination. Second, it builds interruption awareness: knowing a timer is running makes you consciously decide to defer interruptions rather than react to them. Third, mandatory breaks prevent mental fatigue that accumulates during uninterrupted work. Research on cognitive performance shows that brief diversions from a task can dramatically improve ability to focus for prolonged periods. The technique also provides a natural unit for estimating task size — experienced users can estimate tasks as "2 Pomodoros" rather than abstract time, which improves planning accuracy.
Yes — this Pomodoro timer is completely free with no sign-up, no account, no subscription, and no feature paywalls. All features including customizable durations, sound alerts, browser notifications, task input, auto-start, and session stats are available without any registration. The timer runs entirely in your browser and works offline once the page has loaded.
During a 5-minute short break, stand up, stretch, look away from the screen, get a glass of water, or do light breathing exercises. The goal is to give your eyes and focused attention a genuine rest — avoid checking email, social media, or news, as these are cognitively demanding in different ways and prevent true recovery. For a 15-minute long break after four Pomodoros, take a proper away-from-screen break: walk outside if possible, have a snack, or do a short exercise routine. Research on attention restoration suggests that nature exposure or low-demand physical activity during breaks significantly improves performance in the next focus block.
