      Pomodoro study timer for revision

      Revision goes wrong in two ways: never starting, and sitting for three hours without taking anything in. A set of timed pomodoros fixes both, because each one is short enough to start and ends with a real break.

      The short answer

      For revision, 25 minutes of focus and a 5-minute break suits most people; once you can hold attention longer, 50 and 10 halves the number of stops. A set of four 25-minute pomodoros with its breaks and a 15-minute long break takes 130 minutes, just over two hours. Decide what each pomodoro is for before you press Start.

      How to use it

      Three steps to a timer on the wall

      1. Step 1: Choose a time

        Pick a preset or set your own. The timer remembers what you used last on this device.

      2. Step 2: Press start

        Start the timer, then press F or the fullscreen button to fill the screen.

      3. Step 3: Run the room

        Space pauses, the up arrow adds a minute, R resets. Fullscreen shows the timer alone, with no ads and no navigation.

      Running it well

      Four things worth knowing

      • Give each pomodoro a job

        "Chapter 4" is not a pomodoro. "Answer the ten questions at the end of chapter 4 without notes" is. A specific task stops the 25 minutes turning into re-reading.

      • Test yourself in at least one

        Reading notes feels productive and sticks poorly. Spend a pomodoro answering past-paper questions or writing what you remember from a blank page, then check.

      • Put the phone in another room

        A phone face down on the desk still pulls at your attention. Out of reach for 25 minutes is the easiest distraction to remove.

      • Take the break away from the desk

        Stand up, get water, look out of a window. A break spent scrolling is not much of a break, and the next pomodoro starts tired.

      In the room

      Built to be read from the back row

      A timer that only works on the person running it is not doing the job. The digits scale to the screen, the colour changes before the end, and fullscreen shows nothing else at all.

      FAQ

      Questions people ask

      Anything we've missed?

      Tell us

      How long is a set of four pomodoros?

      With 25-minute pomodoros, three 5-minute breaks and a 15-minute long break, a set takes 130 minutes, just over two hours.

      Is 25/5 or 50/10 better for studying?

      Neither is better for everyone. Start with 25/5, and move to 50/10 once you can keep attention for longer without drifting. The second means fewer interruptions for deep work such as essays or problem sets.

      What should I do in the breaks?

      Something away from the screen: stand, stretch, get a drink, look at something far away. Save messages and social media for the long break.

      Can I see how much I studied today?

      Yes. Each focus session you finish adds to today's count under the timer, kept in this browser only.
