How it works
The classic version has four parts. Each one matters more than it looks.
- Choose one task. Not "work on the project", but "write the intro" or "fix the login bug".
- Work for 25 minutes. No email, no tabs, no phone. If something comes up, write it down and keep going.
- Take a 5-minute break. Stand up, look away from the screen, get water.
- After four rounds, take a longer break of 15 to 30 minutes.
Why it works
Starting is the hardest part of most work. A 25-minute block is small enough that your brain stops arguing: you're not committing to finishing, just to the next 25 minutes.
The timer also makes distraction visible. When you feel the pull to check something, you notice it, because you've promised yourself not to until the break. Over a few days you learn what actually pulls at you, and how often.
Breaks matter as much as the work. Short, regular breaks keep your attention fresher for the whole day than one marathon session that ends in a slump.
25 minutes is a starting point, not a rule
The best interval depends on the work. Deep problems need longer to load into your head; admin work suits shorter bursts. Common variations:
- 25/5: the classic. Good for getting started, admin, and days when focus is hard.
- 50/10: better for coding, writing and design, where it takes 10 minutes to get into the problem.
- 45/15: popular for studying, with longer breaks to let things sink in.
- Flowtime: no fixed length. Start a timer, stop when you naturally lose focus, and take a break proportional to how long you worked.
Make distraction harder, not just visible
The technique assumes you'll ignore temptation for 25 minutes. In practice, a notification or a new tab breaks the spell. Remove the easy exits before you start.
In ZenTab, starting a session from the New Tab or popup puts you in focus mode, and the sites you've blocked show a calm block page instead. Focus sounds can play while the timer runs and pause on their own for your breaks, so the sound itself becomes a cue to focus.
Common mistakes
- Skipping breaks because you're "in the zone". If you really are, extend the session, then take a proportionally longer break.
- Counting rounds instead of results. Ten Pomodoros of the wrong task isn't a good day. Choose the task first.
- Giving up after an interrupted round. Interruptions happen. Reset the timer and start again; ZenTab still credits every minute you focused.
