Pomodoro Timer for Studying: How to Set It Up

To use a Pomodoro timer for studying, write down the one task for the next block and set a timer. Use 25 minutes for most tasks, or 40–50 minutes for problem sets and essays. Work only on that task until the timer ends, take a 5-minute break, then start the next block. After three or four blocks, take a longer break of 15–30 minutes.

You don't need a special app to start. The Clock app on a Mac has a countdown timer, and the Clock app on Windows has Focus sessions with optional breaks. A dedicated app helps when you want your task list and the timer in the same place, so you aren't switching windows every 25 minutes.

If you're new to the method itself, start with what the Pomodoro technique is. This page is about making it work for studying.

Why Pomodoro works for studying

Studying usually goes wrong in one of two ways. You never quite start, or you sit for three hours and take in little during the last hour. A timer helps with both.

• A fixed end makes starting easier. "Study chemistry" has no end. "Do questions 1–4 until the timer rings" does.
• One task per block forces a decision. You have to choose what studying means right now: reading, recall or problems.
• Breaks come before you're drained. You stop on a schedule, not when you're too tired to continue.
• Counting blocks is more honest than counting hours. Four focused blocks tell you more than "I was at my desk all afternoon."

Pick study block lengths by subject

The classic 25 minutes suits some study tasks and cuts others off too early. Match the block length to the kind of thinking you're doing.

Two rules make longer blocks work:

1. If the timer rings mid-problem, finish the step you're on, which should take a minute or two at most. Then write one line saying exactly where you stopped. That note makes restarting much easier than working from memory.
2. Keep long breaks long. After three or four blocks, take 15–30 minutes away from the desk, whatever block length you're using.

A sample 3-hour study session

Here's an exam-prep session that mixes block lengths. It fits 130 minutes of focused study into 3 hours.

The planning and review slots matter more than they look. Planning means you never spend the first minutes of a block deciding what to do. The review means tomorrow starts with a task instead of a blank page. If you study from a guide you made yourself, how to make a study guide pairs well with this schedule.

What to do in study breaks

Before you stand up, spend 60 seconds on a recall check. Write down two or three points from the block without looking at your notes. If you can't, that topic goes on tomorrow's list. This turns every break into a small review.

During a short break (5–10 minutes):

• Stand up and move away from the desk.
• Drink water.
• Look at something far away to rest your eyes. The 20-20-20 rule is a simple habit to borrow.

During a long break (15–30 minutes): eat, walk or get outside. Leave the room if you can.

What to avoid: anything with no natural end. A social feed, a video or a game can turn a 5-minute break into 40 minutes. If you reach for your phone, start the break timer first so something tells you when to come back.

Use the timer you already have

On a Mac: the Clock app

1. Press ⌘Space (Command-Space) to open Spotlight, type Clock and press Return.
2. Switch to the timer view in the Clock window's toolbar.
3. Set the length (for example, 25 minutes) and start the timer.
4. When it ends, set your break length and start it again.

This is enough if you keep your plan on paper. It doesn't count blocks or switch to breaks on its own, and your task list lives somewhere else. For more built-in options, see how to set a timer on Mac.

On Windows: Focus sessions in the Clock app

1. Open the Start menu, search for Clock and open it.
2. Choose Focus sessions.
3. Pick a session length and choose whether to include breaks.
4. Start the session.

Focus sessions are linked with Windows Do Not Disturb (formerly Focus Assist). If you've uninstalled the Clock app, you need to reinstall it to use Focus sessions. For other options, see the best Pomodoro timers for Windows.

Set up a study timer and checklist in Gubb

We make Gubb, a small app that keeps notes, a checklist and a timer in one window. For studying, that means your plan, your "where I stopped" notes and the countdown all sit together, and you can pin the window above your textbook PDF. Gubb is available for Mac and on the Microsoft Store for Windows. The steps below describe the Mac version.

Write the session checklist

1. Hover over the top of the Gubb window and click + (Create New Note).
2. Add a heading for the session: type #, press Space, then type something like "Bio exam prep".
3. On the next line, type [ ] and press Space. A checkbox appears. Type the first block, for example "Block 1 (25): recall lecture 7".
4. Press Return for the next checklist item. Press Return on an empty item to leave the list.

The checkbox appears when you type [ ] at the start of a line and press Space. Click a box to tick it, and the item is struck through. More syntax is in the Markdown checklist guide.

For priorities, due dates or sub-steps, use a to-do block instead. This helps with an assignment spread over a week:

1. On an empty line, type gubb@todo with nothing else on that line.
2. Type a task in Add a task... and press Return.
3. For more detail, click + (Add new task) to set a Due Date, a Priority and notes.
4. Click Add subtasks on a task to split a problem set into individual questions.

Due dates are dates only, and Gubb doesn't send reminders for them. Details are in the to-do help section.

Start the timer

1. Move the pointer to the right edge of the note to show the button column, then click Timer.
2. Choose Pomodoro (or Countdown). The default length is 25:00.
3. While the timer is stopped, set min and sec to your block length, for example 40 and 0.
4. Click Start.
5. Click the − (Minimize) button in the dialog header. The timer shrinks to a small pill at the bottom of the window, so your checklist stays visible.
6. Click Pin window on top in the right-edge column to keep Gubb above your other windows.

What to know about Gubb's timer:

• Pomodoro mode doesn't cycle by itself. It counts down the same way Countdown does. When a block ends, set your break length and click Start again.
• There's no completion sound. Keep the minimized pill in view while you work.
• Only one timer runs at a time, and quitting Gubb loses it. It keeps running while the dialog is closed or minimized. Clicking Close timer on the pill stops and resets it.
• Stopwatch mode is handy for past papers. Run it to see how long a question really takes you.

Add break reminders as a backstop

Gubb's Break Time feature runs on its own clock, separate from the Timer. It doesn't follow your study blocks. It counts its own work period (60 minutes by default), then starts a micro break of 10–60 seconds, and replaces every few micro breaks with a long break. That makes it a safety net that pulls you off the screen if you forget to start your break.

1. Click Settings in the right-edge column.
2. Open Break Time.
3. Turn on Enable Break Timer (it's off by default).
4. Adjust the settings below, then click Save Break Settings.

When a break starts, the Gubb window goes full screen and stays on top. It shows a countdown and the buttons +1 Minute and Skip Break. Other displays aren't covered, and you can always skip.

Long breaks only come after micro breaks, so turning off Enable Micro Breaks stops long breaks too. The separate micro and long switches aren't saved, and only the main Enable Break Timer switch is. Break reminders run only while Gubb is open. See what a micro break is for why short screen breaks are worth keeping.

Gubb is $59 one-time (lifetime) as of November 2026, and the Mac download includes a 7-day free trial.

Pomodoro timer apps for studying compared

If you're choosing a study timer app for Mac or Windows, these are the main options. We make Gubb, so weigh our view accordingly; we've tried to describe every option fairly. Prices are as of November 2026.

Session suits students who need help resisting distractions. Pro adds website and app blocking on Mac, custom session and break lengths, and sync, so a timer started on the Mac can notify your iPhone when it ends. The free plan shows analytics for only the past 2 days.

Flow suits students on Apple devices who want the focus and break rhythm handled for them. The free version covers the basic Pomodoro features. Check your macOS version first, since the Mac app needs macOS 26 or later.

Gubb suits students who want the plan, notes and timer in one pinned window and prefer a one-time price. It doesn't block apps or websites or count sessions, and its Pomodoro mode won't switch to breaks on its own.

For full roundups, see the best Pomodoro timers for Mac and the best Pomodoro timers for Windows.

Which to pick

• Pick the built-in Clock app if a countdown is all you need and your plan lives on paper.
• Pick Windows Focus sessions if you're on Windows and want free, scheduled breaks.
• Pick Flow if you're on macOS 26 or later and want the timer to run the work-break cycle for you.
• Pick Session if blocking distracting sites or apps is the main problem.
• Pick Gubb if switching between a notes app and a timer is what breaks your focus, and you also want a checklist and break reminders in the same window.

If it doesn't work

The block ended and you didn't notice. Gubb's timer makes no sound when it finishes. Minimize it to the pill and click Pin window on top so the countdown stays visible over your study material.

The timer disappeared. It resets if you quit Gubb or click Close timer on the pill. Only one timer runs at a time.

A break reminder didn't appear, or used the old interval. Make sure you clicked Save Break Settings. If you changed Work Duration Before Break, turn Enable Break Timer off and on again (or restart Gubb) so the new interval applies. Gubb must be running for breaks to fire.

Long breaks never happen. Long breaks only follow micro breaks. Turn Enable Micro Breaks back on and click Save Break Settings.

The window stopped staying on top. When a break ends, "always on top" is turned off, even if you had pinned the window. Click Pin window on top again.

gubb@todo didn't become a to-do block, or ticking tasks doesn't work. The command must be alone on its own line. If you typed it inside other text, create a new note and type gubb@todo on an empty line.

The full-screen break didn't cover your second monitor. Breaks fill only the Gubb window. Move Gubb to the display you study on.

FAQ

Is 25 minutes too short for studying?

For flashcards and reading, 25 minutes usually works. For problem sets and essays, 40–50 minute blocks with 10-minute breaks often fit better, because you spend less of each block getting back into the problem.

How many Pomodoros should I do in a study day?

It depends on your energy and workload. Plan a realistic number, count what you actually finish, and adjust. Our guide on how many Pomodoros a day covers planning in more detail.

Does Gubb's Pomodoro mode switch to breaks automatically?

No. It's a countdown that starts at 25:00 by default. When it ends, set your break length and start it again. If you want breaks scheduled for you, use Flow or Windows Focus sessions.

Can a study timer block distracting websites?

Some can. Session's Pro plan blocks websites and apps on Mac. The Mac Clock app and Gubb don't block anything.
