Pomodoro Timer
Run focused work sessions with custom breaks, sound alerts, progress tracking and a distraction parking lot that helps you stay on one task.
What will this session move forward?
Set one clear target before starting. The timer works best when the next action is obvious.

How to use the Pomodoro Timer
- Pick a single task you want to make progress on.
- Choose the Focus tab and click Start to begin a 25-minute session.
- Work without interruption until the timer rings. Resist the urge to check messages or social feeds.
- Take a Short Break of five minutes to stretch, hydrate or rest your eyes.
- After four focus sessions, take a Long Break of 15 to 30 minutes to recover deeply.
- Repeat the cycle. Each completed pomodoro is tracked in your daily counter so you can measure progress.
Why the Pomodoro Technique works
The Pomodoro Technique was created in the late 1980s by Francesco Cirillo using a tomato-shaped kitchen timer (pomodoro is Italian for tomato). The method exploits two well-known cognitive principles: time-boxing creates artificial urgency that shortcuts procrastination, while regular breaks prevent the steep drop in concentration that occurs after roughly 30 minutes of sustained attention.
Modern productivity research backs the approach. Studies on attention residue show that frequent context-switching erodes performance by up to 40 percent. By committing to a single task for one pomodoro, you eliminate switch costs and enter a flow state more quickly. The mandatory break then resets your working memory and protects against decision fatigue.
Tips for better focus
- Silence notifications, phone on Do Not Disturb, browser tabs closed.
- One task per pomodoro, split larger work into small, well-defined units.
- Park distractions, capture unrelated thoughts in the parking lot instead of switching context mid-session.
- Use breaks wisely, stand up, look at something far away, drink water. Avoid social media which restarts the dopamine loop.
- Track your sessions, knowing you completed eight pomodoros today is far more motivating than vague "I worked all day".
- Adjust the duration, some people focus better with 50/10 or 90/20 cycles. Use the settings to find your rhythm.
Frequently asked questions
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method developed by Francesco Cirillo in the late 1980s. It breaks work into focused intervals called pomodoros, usually 25 minutes, separated by short breaks. After several focus sessions, you take a longer recovery break. This rhythm makes large tasks easier to start, reduces decision fatigue and helps protect attention from constant context switching.
What makes this Pomodoro Timer different?
The power feature is the distraction parking lot. When an idea, message or unrelated task appears during a focus session, you can capture it quickly without leaving the timer or switching apps. The note stays in the current tab so your brain can let it go, then you can review the list during a break. This supports real deep work instead of only counting minutes. To measure word output during writing sessions, see the Word Counter.
Can I customize the work and break durations?
Yes. You can change the focus duration, short break, long break and the number of focus sessions before a long break. The classic setup is 25 minutes of focus, 5 minutes of rest and a longer break after 4 sessions, but many people prefer 50/10 or 90/20 cycles. Settings are kept only for the current browser tab.
Does the timer keep running if I switch tabs?
Yes. The countdown is based on timestamps rather than simply subtracting one second at a time, so it remains accurate when the browser throttles background tabs. The page title can also show the remaining time, which lets you monitor the session from the tab bar while working elsewhere. Sound alerts still depend on your browser and system audio settings.
Are my tasks, notes and stats stored permanently?
No. Focus targets, distraction notes, custom durations and session stats use sessionStorage, which is limited to the current tab. They are not uploaded to PureTools, not shared with a server and not kept as a long-term history. When you close the tab, the browser clears that data, matching the PureTools zero-trace privacy promise. Your data is never used to train AI models or improve machine learning systems.
What is the distraction parking lot and how does it help me focus?
The distraction parking lot is a capture field where you write any thought, idea or interruption that surfaces during a focus session, without stopping the timer or switching tasks. The cognitive mechanism is relief: once an item is written down, your brain no longer needs to hold it in working memory. At the next break, you review the list and decide whether to act on each item or discard it. This directly reduces the mental cost of interruptions and is one of the most evidence-backed tactics in the original Pomodoro Technique for protecting deep work sessions.
How many Pomodoro sessions should I aim for in a day?
Most practitioners target 8 to 12 sessions of 25 minutes, covering 3 to 5 hours of deep work. Research on sustained attention suggests that truly focused cognitive work has a practical ceiling of around 4 to 5 hours per day for most people, beyond that, quality tends to drop faster than quantity rises. The counter on this timer lets you track your completed sessions over time. If you consistently hit 8, try experimenting with fewer but longer cycles such as 50/10 to see whether the quality of your deep work improves per session.
