There are two ways to use a pomodoro timer with friends. Either everyone opens one shared countdown that starts and stops for the whole group, or each of you runs your own 25 minute timer while you can see that the others are focusing too. The first suits a study group that wants to take breaks together. The second suits friends who sit down at different times and still want company.
Roomie Cafe is a free focus timer you share with friends, and it works the second way. We make it, so keep that in mind as you read. We will be clear about what it does not do, and we will point you to a shared countdown when that is what you need.
What is the Pomodoro Technique?
You pick one task, set a timer for 25 minutes, and work on nothing else until it rings. Then you take a short break, usually about five minutes, and start the next round. After four rounds you take a longer break.
Francesco Cirillo started building the method in the 1980s while he was preparing for a university exam. His own site says he challenged himself to concentrate for just two minutes using a kitchen timer shaped like a tomato, which is where the name comes from: pomodoro is Italian for tomato [1]. Cirillo's full method also covers planning, recording interruptions and a process for teams [2].
Why is a pomodoro 25 minutes?
No study chose 25 minutes. Cirillo began with two minute blocks and arrived at longer ones through his own observation and practice [1]. The number stuck because it is short enough that starting does not feel like a big commitment, and long enough to get something real done.
So treat 25 as a default you can change, for example 50 minutes for writing once you are warmed up. What matters more is that the block has a fixed end and a break follows it.
What does research say about timed work and breaks?
The evidence is encouraging but limited. There is no large body of trials on the Pomodoro Technique itself.
The closest direct test is a 2023 study of 87 university students in the Netherlands during a real day of self study. Some took a 6 minute break after every 24 minutes, some took a 3 minute break after every 12 minutes, and some decided their own breaks. The students who decided for themselves studied and rested in longer stretches, and reported more fatigue and distraction and less concentration and motivation. They did not finish more work. The authors concluded that fixed breaks had mood benefits and finished the same amount of work in less time [3]. It is one study over a single day.
A 2022 review pooled 22 samples with 2,335 people to see what short breaks of 10 minutes or less do. Breaks gave a small boost to energy and a small drop in fatigue. The effect on overall performance was not significant, and it showed up mainly for less demanding tasks. Longer breaks gave a bigger performance boost [4].
An earlier lab experiment at the University of Illinois found that attention on a long, dull task faded over time, and that briefly switching to a second task now and then kept that decline from happening [5].
Put together: scheduled breaks seem to make long sessions feel better, and they probably help you keep going. Do not expect a timer to make hard work faster on its own.
Why do pomodoros with friends at all?
Working while other people work makes it easier for many of us to start and keep going, an effect often called body doubling. We explain the psychology behind that in why focusing alone is harder, so we will not repeat it here. Researchers who interviewed neurodivergent people who work this way describe it as a range, from quiet company in the background to active accountability, and people pick the point on that range that suits them [6].
A pomodoro gives that company a shape. Everyone knows when the focus block ends and when it is fine to talk.
How does a shared pomodoro timer work?
In this setup one person creates a timer, shares a link, and every screen shows the same countdown. When it hits zero, everyone breaks at once.
Leaderboarded, a tool built mainly for scoreboards, runs a free shared study timer that works this way. Only the person who creates the timer needs an account. Everyone else opens the link, and the creator presses start for the whole group. Leaderboarded notes that its timer does not cycle through work and break on its own, so someone resets it between blocks [7].
Some study apps build pomodoros around rooms you join with other people. Focumon runs focus sessions that are multiplayer by default, lets you invite friends by sharing the link to your own training center, and has parties of up to six people. It is free with a 4 hour focus limit, and Pro costs $6 a month [8, 9]. PomoPals offers themed focus rooms such as a library and a classroom, plus leaderboards. It is free on iOS and Android, with paid plans at $2.99 a month or $12.99 a year [10, 11]. Check each app yourself to see whether a room shares one timer or shows each person's own.
A shared countdown is the better choice when your group sits at the same table or on the same call and wants to talk in the same breaks. The downside is that everyone has to be free at once, so a late friend joins halfway through a block.
Can you do pomodoros with friends on separate timers?
Here each person presses start when they are ready. You do not share a countdown, but you can see who else is focusing right now and what they are working on.
This is how Roomie Cafe works. You press start, pick a focus area such as "Thesis" or "Spanish", and choose a length anywhere from 5 to 90 minutes, so a 25 minute pomodoro is one tap away. Friends you follow appear at the top of Home while they are focusing. Nobody sees or hears you: there is no webcam and no microphone. People only see your name, what you are working on and your timer. When the timer ends you write one line about what you got done, and friends can cheer you on.
To be plain about the limits: Roomie Cafe does not sync one timer for a group, it has no group rooms and no chat, and it does not run your breaks for you. If you need everyone to break at exactly the same second, use a shared countdown for that.
The advantage is company that does not depend on schedules lining up. A friend in another time zone can start a session at their 9:00 while you are on your third pomodoro of the afternoon, and you both see each other in the row. Your finished sessions also build into a focus history, shown as a heat calendar next to your total focus time. There are no streaks to keep alive, so a missed day costs you nothing.
Roomie Cafe is free with no limit on sessions. An optional Supporter plan is on the pricing page if you want to fund it.
How to set up pomodoros with friends
For a shared countdown:
- Agree on the block length in your group chat. 25 minutes with a 5 minute break is a fine start.
- One person creates the shared timer and posts the link.
- Say what you will work on before you start, in one sentence each.
- Keep chat and calls muted during the block. Talk in the breaks.
- After four rounds, take a longer break or stop for the day.
For Roomie Cafe:
- Open Roomie Cafe on the web, or get the iPhone, iPad and Mac app.
- Follow your friends so they show up at the top of Home.
- If you want to start together, post a time in your group chat and each press start at that time with 25 minutes.
- Pick a focus area and work until the timer rings.
- Write one line about what you got done, cheer a friend, take your break, and start the next round when you are ready.

FAQ
How do you do pomodoro with friends online?
Either share one timer link so everyone follows the same countdown, or each run your own timer in an app where you can see who else is focusing. Agree on a block length and keep talking to the breaks.
Is there a shared pomodoro timer online?
Yes. Some tools show the same countdown on every device that opens a link, with one person controlling start and reset. Leaderboarded offers a free one where only the creator needs an account.
Why is pomodoro 25 minutes?
Francesco Cirillo settled on it through his own practice, starting from two minute blocks. No study shows that 25 minutes is ideal, so adjust it to the task.
Is the Pomodoro Technique backed by research?
Partly. A 2023 study of 87 students found fixed breaks led to less fatigue and better mood than breaks students chose themselves, with the same work done. Research on short breaks shows small gains in energy, with mixed effects on performance.
Can you use Roomie Cafe as a group pomodoro timer?
Not as one synced countdown. Each person runs their own timer from 5 to 90 minutes, and you see which friends are focusing at the same time.
