About this tool
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s, named after the tomato-shaped kitchen timer he originally used to track his work sessions. Structured work intervals reduce decision fatigue and create a natural rhythm for deep work - the technique's main benefit is not the timer itself, it is the commitment to a defined block of time, which reduces procrastination and task-switching.
This Pomodoro timer runs a 25-minute focus session by default, followed by a 5-minute short break - and a 15-minute long break after every 4th session - with all three durations fully customizable. When a session ends, the timer stops and switches to the next phase automatically, ready for you to start manually; it doesn't play a sound or send a browser notification, so keep the tab visible if you want to catch the moment it ends.
How to Use Pomodoro Timer
Set Durations
Customize focus, short break, and long break times.
Start Timer
Hit start and focus on one task during the work session.
Take a Break
When the session ends, the timer switches to your scheduled short or long break - click Start again to begin it.
Track Sessions
Monitor completed Pomodoros and long breaks over your session.
Common Workflows
Run the Default 25/5 Cycle
Click Start to begin a 25-minute Focus session; when it ends, the timer automatically sets up the next phase - a 5-minute Short Break, or a 15-minute Long Break after every 4th session.
Customize Your Session Lengths
Adjust the Focus, Short Break, and Long Break durations in the Customize Durations section - each field accepts any whole number of minutes from 1 upward.
Start Each Phase Manually
The timer stops and waits after each phase ends - click Start again to begin the next Focus session or break rather than expecting it to continue on its own.
Switch Phases Directly
Use the Focus / Short Break / Long Break tabs to jump to a different phase manually at any time, resetting that phase's timer to its full duration.
Watch the Session Count
Track your pomodoro and long-break counts live in the timer footer - keep the tab open, since the count is not saved if you refresh or close the page.
Best For
- Runs the standard Pomodoro cycle - 25 minutes work, 5 minutes short break, 15 minutes long break every 4th session - with all three durations independently customizable from 1 minute up.
- Tracks completed pomodoros and long breaks live on the page - the count resets if you refresh, since nothing is saved between visits.
- Browser-based: no app install, no account, works in any browser tab you keep open.
Examples
A full 4-session cycle at the default settings
Phase Sequence
Focus, Short Break, Focus, Short Break, Focus, Short Break, Focus, Long BreakDuration
25m, 5m, 25m, 5m, 25m, 5m, 25m, 15m (100 minutes total, including breaks)After every 4th completed Focus session, the timer switches to the 15-minute Long Break instead of the usual 5-minute Short Break - each phase still requires clicking Start manually, since the timer never begins the next phase on its own.
Use Cases
Structuring a deep-work session
Use the default or an extended Focus duration to block out uninterrupted time for writing, coding, or studying.
Breaking a large task into manageable chunks
Use repeated 25-minute Focus sessions to work through an intimidating task one interval at a time.
Building a work rhythm with regular breaks
Let the automatic short-break and long-break scheduling create a consistent on/off rhythm across a work session.
Common Mistakes
Problem
Expecting a sound or notification when a session ends
Solution
This timer does not play a sound or send a browser notification - it only changes the on-page display, so you need to be watching the tab, or check back periodically, to know when a session finishes.
Problem
Assuming the next phase starts automatically
Solution
The timer stops and switches to the next phase's full duration when one ends, but it does not start counting down on its own - click Start again to begin it.
Problem
Leaving the tab in the background for a long session
Solution
This timer uses a standard JavaScript countdown, not a background-safe mechanism - browsers can throttle timers in inactive tabs, so the displayed time can drift from real elapsed time if you switch away for a while.
Problem
Expecting the session count to survive a refresh
Solution
Pomodoro and long-break counts, along with any custom durations you have set, all reset to their defaults if you reload the page.
Tips & Best Practices
Keep the tab visible if you're relying on it to alert you
Since there is no sound or notification, glance back at the tab as a session nears its end rather than assuming you will be alerted.
Pair long sessions with your own reminder
For a long Focus or Long Break duration, consider setting your own phone alarm alongside this timer, since it will not notify you when time is up.
Try 45- to 50-minute sessions if 25 minutes keeps interrupting your flow
Longer sessions can suit deep, complex work better once you are used to focusing - adjust the Focus duration directly rather than restarting a 25-minute timer repeatedly.
Use the phase tabs to skip ahead deliberately
If you need to jump straight to a break or restart a Focus session, use the Focus / Short Break / Long Break tabs instead of waiting for the current phase to finish.
Limitations
No sound or browser notification
The timer does not play an audio alert or send a browser notification when a session ends - the only signal is the on-page display changing.
No background-tab protection
This timer uses a standard JavaScript countdown rather than a background-safe timing mechanism - browsers can throttle timers in inactive tabs, so real elapsed time can drift from the displayed countdown if the tab is not active.
No persistence between visits
Nothing is saved - your custom durations, current phase, and pomodoro/long-break counts all reset to their defaults if you refresh or close the tab.
No auto-start between phases
Each phase - Focus, Short Break, Long Break - requires a manual click on Start; the timer never begins the next phase on its own.
No task list or productivity tracking
This is a timer only - it does not let you attach tasks to sessions or keep any history beyond the current visit's session count.
Comparisons
25-Minute vs. 50-Minute Focus Sessions
Both use the identical countdown mechanism - only the Focus duration you set changes the rhythm of your work session.
| 25-Minute Sessions (Default) | 50-Minute Sessions (Custom) | |
|---|---|---|
| Focus sessions per hour of work | About 2, each followed by a break | About 1, followed by a break |
| Best suited for | High-frequency-decision tasks, or building the focus habit | Deep, complex work once you're used to sustained focus |
| Long break still triggers after | 4 completed Focus sessions | 4 completed Focus sessions |
Which should you use?
There is no single correct interval - set the Focus duration to whichever length keeps you working through a session without losing momentum, and the 4-session long-break cycle adjusts around it automatically.
FAQs
The most common question is whether 25 minutes is the right interval for everyone. It's a widely used starting point, but longer, uninterrupted blocks - often cited as roughly 50 to 90 minutes - can suit deep, complex work better once you're used to sustained focus, while shorter 25-minute sessions work well for high-frequency-decision tasks or when you're still building the habit. Adjust the Focus duration directly if 25 minutes feels too short for your workflow.
How many Pomodoros before a long break?
After completing 4 Pomodoro sessions, you take a longer break (typically 15-30 minutes) to rest and recharge.
Can I customize the Pomodoro timer durations?
Yes. This tool lets you set your own focus time, short break, and long break durations to fit your personal workflow.
