Pomodoro Focus Timer
Free online Pomodoro timer. Work in focused 25-minute sessions, take short breaks, and repeat. After four sessions, take a longer break. Customize all durations below.
How to Use the Pomodoro Timer
- Pick one task to focus on -- not a list, one specific thing.
- Press Start and work only on that task for 25 minutes. No email, no phone, no switching.
- When the timer rings, stop. Take a 5-minute break away from your screen.
- Repeat. After four work sessions, take a longer 15--30 minute break.
That's the core of the Pomodoro Technique. One task, one timer, full focus.
The Pomodoro Technique Explained
The Pomodoro Technique is a time management method created by Francesco Cirillo in the late 1980s while he was a university student struggling to focus. He used a tomato-shaped kitchen timer (pomodoro is Italian for "tomato") to commit to just 10 minutes of focused study -- and it worked.
The method has five steps:
- Choose a task you want to work on.
- Set the timer for 25 minutes.
- Work on the task until the timer rings. If a distraction pops up, write it down and return to the task.
- Take a 5-minute break.
- After four pomodoros, take a 15--30 minute break.
Why 25 minutes?
Research on sustained attention shows that most people maintain peak focus for 20--30 minutes before performance declines. The 25-minute interval is long enough to make meaningful progress but short enough that the end is always in sight -- which reduces the urge to procrastinate.
Why breaks matter
Breaks are not wasted time. Short pauses allow your brain to consolidate information, reset attention, and reduce mental fatigue. Studies on distributed practice show that spaced work sessions produce better retention and performance than unbroken marathons.
Common Timer Variations
The classic 25/5 pattern works well for most people, but you can adjust based on your task type:
| Variation | Work | Short Break | Long Break | Best For |
|---|---|---|---|---|
| Classic | 25 min | 5 min | 15 min | General tasks, studying |
| Deep work | 50 min | 10 min | 30 min | Programming, writing, analysis |
| Short burst | 15 min | 3 min | 15 min | Admin tasks, email processing |
| Extended | 45 min | 15 min | 30 min | Creative work, design, research |
Use the settings panel above to adjust all three intervals. The timer automatically cycles between work and break modes.
Example: A Pomodoro Study Session
Student studying for an exam -- 3 hours
- Pomodoro 1 (25 min): Read chapter 5, take notes on key concepts
- Break (5 min): Stretch, get water
- Pomodoro 2 (25 min): Summarize chapter 5 in own words
- Break (5 min): Walk around
- Pomodoro 3 (25 min): Practice problems from chapter 5
- Break (5 min): Snack
- Pomodoro 4 (25 min): Review errors, re-read weak areas
- Long break (15 min): Step outside, reset
- Pomodoro 5--6: Move to chapter 6, repeat cycle
Result: 6 pomodoros = 2.5 hours of actual focused study in a 3-hour window. That's more real focus than many people get in an entire day of "studying."
Handling Interruptions
Interruptions are the biggest challenge with the Pomodoro Technique. Cirillo distinguishes two types:
Internal interruptions
A thought pops up: "I should check that email" or "I forgot to buy milk." Write it down on a piece of paper or in a notes app, then return to your task immediately. Deal with it during your break. This is called the inform, negotiate, call back strategy.
External interruptions
Someone taps your shoulder or sends an urgent message. You have two choices:
- Defer: "I'm in the middle of something -- can I get back to you in 15 minutes?" Most things can wait.
- Void: If you must stop, mark the pomodoro as interrupted and restart it from zero once you're back.
Tracking how many pomodoros you void per day reveals patterns. Many people discover their "urgent" interruptions could have waited.
Frequently Asked Questions
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. You work in focused 25-minute intervals (called pomodoros), separated by 5-minute breaks. After four pomodoros, you take a longer 15--30 minute break. The name comes from the tomato-shaped kitchen timer Cirillo originally used.
Why does the Pomodoro Technique use 25 minutes?
Cirillo found that 25 minutes is long enough to make meaningful progress but short enough to maintain consistent focus. Research on sustained attention suggests most people concentrate deeply for 20--30 minutes before performance drops. The 25-minute interval sits in that effective range.
How many pomodoros should I do per day?
Most people complete 8--12 pomodoros in a productive workday, which equals about 3.5--5 hours of actual deep focus. The remaining work hours typically go to meetings, communication, breaks, and low-focus tasks. Tracking your count helps you understand your true focused work capacity.
Can I change the timer length?
Yes. While the classic technique uses fixed 25/5 intervals, many people adjust the durations. Common variations include 50/10 for deep work, 15/3 for short tasks, and 45/15 for creative work. Use the settings panel on this page to customize all three intervals.
What should I do during breaks?
Step away from your screen. Stretch, walk, get water, look out a window, or do a brief breathing exercise. Avoid checking email, social media, or starting another focused task. The goal is to let your brain rest so the next pomodoro is productive.
What if I finish my task before the timer ends?
Use the remaining time for review, improvement, or related micro-tasks. Cirillo calls this "overlearning" -- reviewing what you just did or planning ahead. Don't start the break early; maintaining the consistent rhythm is part of the method.
What if I get interrupted during a pomodoro?
For internal distractions (thoughts, ideas), write them down and return to your task. For external interruptions, either defer the request ("I'll call you back in 15 minutes") or void the pomodoro and restart it. Tracking interruptions helps you reduce them over time.
Does the Pomodoro Technique work for studying?
Yes. The technique is widely used by students because it breaks study sessions into manageable chunks, reduces procrastination, and builds in regular breaks that aid memory consolidation. Many students retain more material using timed intervals than during long unstructured sessions.
