What is the Pomodoro Technique?
The Pomodoro Technique is a time management methodology developed by Francesco Cirillo in Italy in the 1980s. It involves focusing on a single task for 25 minutes, followed by a 5-minute break, and taking a 15-30 minute long break after 4 cycles.
This online Pomodoro timer provides features optimized for the Pomodoro Technique, including automatic session switching, statistics tracking, and screen wake lock. Use it directly in your browser with no installation required.
Key Features
Auto Session Switching
With auto-start enabled, focus → break → focus continues automatically. Turn it off to start each next block yourself. A long break follows the fourth focus session.
Flexible Time Settings
Adjust focus time (1-90 min) and break time in 5-minute increments to find your optimal duration.
Pomodoro Statistics
Stores completed focus sessions and the sum of their configured minutes in this browser. It does not measure work quality or output.
15 Alarm Sounds & Vibration
Choose from 15 alarm sounds including Soft Bells, Arpeggio, Good Morning, Solemn Bell, and Rooster, with adjustable volume. Vibration alerts are supported on touch devices.
Screen Wake Lock
Requests that supported browsers keep the display on. Sleep settings, battery state, or switching tabs may release the request.
How to Use
- Step 1: Set Time — Use the default 25 min focus / 5 min break or adjust with ± buttons.
- Step 2: Configure — Choose an alarm sound and volume, and adjust focus/break durations to your liking.
- Step 3: Start Focus — Press Start and immerse yourself in a single task.
- Step 4: Break & Repeat — When the alarm rings, take a 5 min break. Take a long break after 4 sessions.
Use Cases
Study & Exam Prep
Set a block for a chapter or group of practice questions, then check how much work was actually completed.
Coding & Development
Mark a start and rest point for coding or design work, then adjust the block length to fit the task's flow.
Reading & Writing
Use for reading, report writing, blog posts, and other tasks requiring sustained concentration.
Practice Tests
Simulate actual test conditions with time limits and manage break times between sections.
Frequently Asked Questions (FAQ)
What is the Pomodoro Technique?
Developed by Francesco Cirillo in the 1980s. Start with 25 minutes of focus, then 5 minutes of rest, and take a longer break after four focus sessions. This timing does not guarantee greater productivity or less fatigue for every task.
Can I change the focus time from 25 minutes?
Yes. Enter a focus time from 1 to 90 minutes directly, or use the ± buttons, which usually change it by five minutes. Short and long breaks can each be set from 1 to 30 minutes. Compare settings on similar work.
How do I check my Pomodoro statistics?
When a focus session finishes while the page is open, this browser records today's, this week's, and the last 90 days' session counts and configured focus minutes. Sessions that elapse while the tab is closed are not counted. The figures do not measure work output.
Does the timer stop if I close the tab?
Closing the tab prevents alerts. Other tabs, screen lock, or sleep can restrict browser execution and delay alarms or the next session. Keep the screen on for important sessions and check the remaining time and session state when you return.
Can I change the alarm sound or use vibration?
Yes, you can choose from 15 alarm sounds including Soft Bells, Arpeggio, Good Morning, Solemn Bell, and Rooster, and adjust the volume. On touch devices such as smartphones, vibration alerts are also available.
Is this service free?
Yes, the Pomodoro Timer is completely free with no registration or installation required. Use it directly in your browser.
What Focus-and-Break Research Can Tell Us
In DeskTime's analysis of its users' activity, a 52-minute work and 17-minute break pattern was observed among high-scoring users during one workday in 2014. A 2021 follow-up found a different pattern. Observational data cannot show that following a particular interval causes better output.
Treat 25/5 as a starting setting. For comparable work, note output, errors, interruptions, and fatigue; then adjust the intervals if breaks interrupt useful progress. This timer counts completed time blocks, not the quality of the work done in them.
Try Intervals That Fit the Task
Coding: If a 25-minute cue repeatedly interrupts problem solving, compare a 45–50 minute block. Itemized code review may fit a shorter block.
Writing: Give each block an observable goal, such as a draft introduction. If a paragraph is hard to stop midway, finish it before resting.
Studying: Note problems completed or review errors separately from time spent. Follow actual exam time rules when practicing for an exam.
Design: Idea generation and repetitive revision may have different rhythms; do not force the same interval on both.
Pomodoro Settings to Compare by Task
Twenty-five minutes of focus and five minutes of rest are starting values. These rows are settings you can enter on this page to compare similar work, not proven prescriptions for a profession. Review output, interruptions, and fatigue before keeping an interval.
| Example task | Focus | Short break | Long break | What to check |
|---|---|---|---|---|
| Basic start | 25 min | 5 min | 15 min after 4 | Actual work finished in a block |
| Long draft or coding | 50 min | 10 min | 15 min after 4 | Whether a 25-minute cue disrupts progress |
| Problem sets or itemized review | 20 min | 5 min | 15 min after 4 | Track both output and errors |
| Between emails or customer calls | 15 min | 5 min | 15 min after 4 | Pause if a call arrives |
| One mock exam | 80 min | 20 min | 15 min after 4 | Follow the real exam time rules first |
This timer schedules a long break only after the fourth focus session. You can edit the focus and break lengths shown here, but not the long-break frequency. For a single exam block, reset afterward. Browser alarms may be delayed by lock or sleep, so do not rely on this page as the only clock for a consequential exam.
