Pomodoro Timer Online
StudyClock's Pomodoro timer is a free online timer for focused study. It opens at 25 minutes, and you press play to start your first focus session. You do not need an account to use the timer. When the 25 minutes are up, it plays an alarm and switches to a short break, then back again, so you study in steady blocks instead of one long stretch.
It also works with your task list and the Chapter Tracker, so a focus block can count toward a specific task or chapter rather than just passing the time.
How the Pomodoro method works
A "Pomodoro" is one 25-minute block of focused work followed by a 5-minute break. The name is the Italian word for tomato, after the tomato-shaped kitchen timer the method's creator used.
The basic cycle is short:
- Pick one task.
- Work on only that task for 25 minutes.
- Take a 5-minute break away from the screen.
- After four rounds, take a longer break of 15 to 30 minutes.
Francesco Cirillo created the technique as a university student in the late 1980s and later wrote a book about it. The thinking is that a 25-minute block feels small enough to start even when you are putting the work off, and the fixed break gives you a clear stopping point.
The method is not magic, and the 25/5 split is not a rule. It is a starting point that many students find easy to stick to. If a different rhythm works better for you, the timer lets you change it, which the next sections cover.
How to use the StudyClock Pomodoro timer
You can start in a few seconds:
Open the Pomodoro timer. It loads on the Focus tab at 25:00.
Decide what you will work on for this block. One task is enough.
Press the play button. The countdown starts, and the time also shows in your browser tab title, so you can see it from another tab.
Study until the alarm sounds. Try not to switch tasks in the middle.
When the block ends, the timer moves to Short Break. Stand up, look away from the screen, drink some water.
Press play again for the next focus block. After four focus blocks, use the Long Break tab for a longer rest.
Two small icons near the timer control how it tells you a block is over. One toggles a browser notification, and one toggles the alarm sound. You can turn on either, both, or neither. The reset button sends the current block back to its full time if you need to start it again.
The timer counts from the real clock time, not from a number it adds up second by second. So if you switch tabs or leave the page for a bit, the time left is still correct when you come back.
Change the timer length
The default is the standard 25/5 setup with a long break, but you can change every part of it. Open Customize Timer under the clock and set your own focus length, short-break length, and long-break length.
Common changes students make:
- 50/10:
a 50-minute focus block with a 10-minute break, for work that takes a while to get into.
- 15/3:
shorter blocks for days when you are tired or the task is dull.
- 25/15:
the normal focus block with a longer long break, when four rounds leave you drained.
If you have a free account, you can save these as timer packages and switch between them. Only one package is active at a time, so your "exam week" setup and your "light revision" setup do not get mixed up. Saved packages sync to your account, so they are there on your phone and your laptop.
Alarm sounds and notifications
Open Customize Alarm Sound to pick the sound that plays at the end of a block. This helps if the default is too soft to hear with headphones on, or too sharp for a quiet library.
You have three ways to be told a block is done, and you can combine them:
- The alarm sound.
- A browser notification, which is useful if the tab is in the background.
- The live countdown in the browser tab title, which you can watch without leaving your current tab.
Link a task or a chapter to your session
Under the timer there are three tabs: Tasks, Chapters, and Revisions. These need a free account, because they save to your profile and not just to your browser.
Tasks is a simple study to-do list. You add tasks, mark them done, and see a count of total, done, and pending. You can add tags to group tasks by subject or exam. The "Link a task" dropdown ties your current focus block to one task, so the time you study counts toward that task.
Chapters is the Chapter Tracker. You add a chapter with its subject and, if you want, the exam name and date. For each chapter you set a difficulty and a confidence score from 1 to 5, and the tracker shows a progress percent. When you use "Link a chapter" during a focus block, that study time is added to the chapter's total, along with the session count and the date you last studied it.
Revisions is where the tracker earns its place. After you study a chapter, it schedules spaced review dates for you: a first revision, then a second, then a third, each one further apart. Spacing your reviews out like this, instead of rereading everything the night before, is one of the study habits that research reviews rate most highly. One example is a 2013 review by Dunlosky and colleagues in Psychological Science in the Public Interest. The Revisions tab is your list of what to review and when.
This turns the timer from a plain clock into a record of what you studied and what still needs work.
Sounds and focus mode
A few controls help you settle in:
Ambient sound mixer:
mix background sounds such as rain or a cafe, and save a mix you like.
Music:
play background music while you work, with playback that continues as you move around the site.
Picture-in-picture:
pop the timer out into a small floating window that stays on top of other apps, so you can watch the time while you read a PDF or write in another window.
Fullscreen:
hide everything on the page except the timer.
What it tracks over time
Every finished focus block is saved as a study session when you are signed in. Those sessions feed the analytics dashboard, which shows your total study time, a focus score, simple insights about your best times of day, and a CSV export if you want the raw data. Finished blocks also count toward your daily streak, toward badges such as the one for total Pomodoros completed, and toward the leaderboards if you use them.
On the free plan you keep 7 days of analytics history, which is enough to see your week. Longer history is part of the paid plan, but nothing about the timer itself is behind a paywall.
Studying with other people
If you focus better next to other people, StudyClock's study rooms have a shared Pomodoro. In a study group room, up to 20 people share one timer, so everyone starts, stops, and breaks at the same time. That is a different page from this one, and you can find it under Study Rooms. Sitting with other people who are also working makes it easier for many students to stay off their phone.
Where the Pomodoro method struggles
The 25-minute block is not right for everything. It gets in the way when:
You are in deep flow.
If you are finally deep in a hard problem, a break bell can cut your train of thought. Some people use longer blocks, such as 50 minutes, for this kind of work.
You are doing a timed mock exam.
For that you want one fixed countdown for the whole paper, not blocks. Use the countdown timer instead.
You just want to study and watch time add up.
If you do not want a fixed target, the study timer counts upward from zero, and the online stopwatch is plainer still.
Your work comes in unpredictable interruptions.
Frequent messages or questions will keep cutting your blocks short, and restarting the timer each time gets tiring.
The method also depends on protecting the 25 minutes. If you check your phone twice during a block, it is not really a focus block. The timer keeps the time for you, but staying off distractions during those minutes is still your job.

Is it free, and do I need an account?
The timer is free, with no sign-up, no download, and no time limit. You can open the page and start a 25-minute block right away.
A free account adds the parts that need to be saved: the task list, the Chapter Tracker and its revision schedule, saved timer packages, session history, streaks, and analytics. Creating one takes an email address or a Google sign-in. The paid plan is mainly for AI study tools and longer analytics history, and it does not change how the timer works.
FAQ
Yes. The timer works with no account, no download, and no time limit. A free account only adds saved features such as the task list, Chapter Tracker, and history.
No. Open Customize Timer and set any focus length, break length, and long-break interval you want. The 25/5 split is only the default.
Yes. It counts from the real clock, and the time left shows in the browser tab title, so it stays correct when you come back to the page.
Yes. It runs in the mobile browser with no app to install. You can also add StudyClock to your home screen as a web app.
It ties your current focus block to a chapter in the Chapter Tracker. The time you study is added to that chapter's total, and the tracker uses it to schedule your spaced revisions. This needs a free account.
Yes, if you turn the alarm on. You can also turn on a browser notification. You pick the alarm sound under Customize Alarm Sound.
Yes, in StudyClock's study rooms. A study group room gives up to 20 people one synced Pomodoro so everyone breaks together. It is a separate page under Study Rooms.
The timer keeps running if your connection drops during a session. Saving sessions, tasks, and chapters needs a connection so they can sync to your account.
There is no correct number. Many students aim for 8 to 12 focus blocks across a study day, with proper breaks and at least one long break. Start lower and build up.
Start a focus session
Open the timer, pick one task, and press play. If you study better with a record of it, sign in first and link the block to a task or a chapter.
