Pomodoro Timer

25-minute focus sessions with short breaks and a visual progress ring.

The Pomodoro Technique breaks work into 25-minute focus sessions separated by 5-minute breaks. After four sessions you take a longer 15–30 minute rest. Each sprint targets one task, and the short, regular breaks are what keep your concentration sharp through a long study day.

How to use the Pomodoro Technique well

Before you press start, write down the one task you will work on for the next 25 minutes — “read chapter 4,” not “study biology.” A vague goal lets your mind wander; a concrete one gives the sprint a finish line. When the focus session ends, actually take the break: stand up, look away from the screen, move. The break is what makes the next sprint possible.

The timer counts a 25-minute focus session followed by a 5-minute break, then loops. The shrinking ring shows time left at a glance, so you can stay in the work instead of watching digits. The “focus sessions completed” counter ticks up each time you finish a sprint — a simple tally of real work done.

  1. 1
    Pick one concrete task. Name a finishable goal for the sprint — “read chapter 4,” not “study biology” — so the 25 minutes have a clear finish line.
  2. 2
    Start a 25-minute focus session. Work only on that task with no tab-switching or phone; if a stray thought pops up, jot it down and keep going.
  3. 3
    Take a 5-minute break when the timer rings. Stand up, stretch, drink water and look away from the screen — the short rest is what keeps the next sprint sharp.
  4. 4
    Repeat, then take a long break. After four focus sessions, step away properly for 15–30 minutes before starting the next set.
  5. 5
    Log it and line up the next task. Note what you finished, choose the next concrete task, and start the timer again.

The classic cycle

Four focus sessions make one set; take a longer rest before starting the next set.

Getting more out of each session

Protect the 25 minutes. If a stray thought or task pops up, jot it on a scrap of paper and return to the work — don’t act on it mid-sprint. Most interruptions can wait five minutes.

Don’t skip breaks to “push through.” The rest is not wasted time; it’s what stops the third hour from being useless. Skipping breaks is how a focused start turns into burnout by mid-afternoon.

Match the task to a sprint. Tasks that need deep thought fit one or two sessions well. For shallow admin work, batch several small jobs into a single 25-minute block.

This version uses the fixed 25/5 split, which suits most study. If you find 25 minutes too short for problem sets, the principle still holds — just run two sessions back-to-back through the short break.

Pair the timer with a clear weekly plan: a study planner turns your hours into the exact number of sessions each subject needs, and an exam countdown keeps the deadline in view.

Does the timer keep running if I switch tabs?
Yes — it runs in your browser. Keep the tab open and it counts down in the background, switching automatically between focus and break.
Can I change the durations?
This version uses the classic 25/5 split. To run a longer block, let two sessions run back-to-back through the short break.
Why 25 minutes specifically?
It is long enough to make real progress but short enough that starting feels easy and your attention rarely fades before the break.
What does the Skip button do?
It jumps to the other phase — from focus to break, or break to focus — without finishing the current timer. Use it when you stop early or want to start a break sooner.
Should I really take every break?
Yes. The breaks are what keep later sessions productive. Skipping them to push through is the fastest route to burning out by mid-afternoon.
What counts as a “completed” session?
Each time a 25-minute focus timer reaches zero, the counter goes up by one. It is a simple tally of focused work, not an estimate of hours.
