What is body doubling?

Body doubling is working on your own task while someone else is present and doing the same. The quiet sense of company makes it easier to start and harder to drift off. Focus Rooms bring that effect to your screen without a video call.

Yes. The full Pomodoro timer, all 16 themes, free music, streaks, statistics, up to 7 tasks, and joining public Focus Rooms are free forever. Premium adds unlimited tasks, the ability to create and go private in rooms, the full music library, and year-long stats.

Do I have to turn my camera on in a Focus Room?

No. There is no video and no microphone. Other people see your status (focusing, on a break, paused) and nothing else.

Which platforms is Kaizen on?

iOS, Android, the web as an installable app, and Windows through the Microsoft Store. Your timer, tasks, and stats sync across all of them.

Does the timer keep running if I switch apps?

Yes. The timer uses the system clock, so it stays accurate when you lock your phone or switch apps, with a notification to bring you back.

Pomodoro timer + Focus Rooms

Focus better, together

Kaizen is a Pomodoro timer with Focus Rooms: quiet spaces where you study next to other people in real time. No video, no small talk. Just the steady pull of a room full of people getting work done.

The problem

Willpower runs out. A room full of people doesn't.

You sit down to study, then your phone wins. Again. Focus Rooms fix this the way a library does, not with another blocker app, but with other people. When someone can see you are focusing, you keep focusing.

Focus Rooms

Study alongside people who are also heads-down

Join a public room for free, or spin up your own. Everyone runs their own timer, and you can see who is focusing, who is on a break, and who stepped away. Around 95% of people focus better with someone else there, an effect called body doubling.

See who is focusing
Live status for everyone in the room, focusing, on a break, or paused, plus the tag each person is working under.
Public rooms are free
Browse and join open study rooms without paying. Create or go private on Premium.
2 to 50 people
Sit in a small study group or a packed hall. You set the size.
Presence that means something
Leave the app for more than 15 minutes and you are removed. Being there is the point.

How Focus Rooms work

The timer

A Pomodoro timer you will actually want to look at

Pick a preset or set your own from 5 to 180 minutes. It keeps perfect time in the background and tells you when to switch, so you can stop watching the clock and start working.

Your intervals
Classic 25/5, Quick, Extended, Long Focus 90/15, or anything from 5 to 180 minutes.
Runs in the background
Built on the system clock, so it stays accurate with the screen off or the app closed.
Knows when to nudge
Sounds, vibration, and a controllable notification when a session ends.
Immersive mode
Hide everything but the timer when you want zero distraction.

Tasks

Know exactly where your time went

Pin a task, start the timer, and Kaizen logs the minutes against it on its own. No stopwatch, no guessing afterwards.

Tap to focus
Set one task active. Every minute you work counts toward it automatically.
Subtasks and estimates
Break big work down and watch the progress fill in. (Premium)
Synced everywhere
Your tasks and tracked time follow you across every device.

Explore task management

Progress

Watch the hours add up

The work does not vanish when the timer stops. Kaizen keeps a daily streak going and turns your focused minutes into stats you will actually want to check.

Daily streaks
Milestone tiers shift colour as your streak grows. Showing up is the habit.
See your focus time
Today, this week, and this month for free. Premium opens the full year.
Focus by tag
Label a session Work, Study, or Personal and see where your hours actually go.
Find your patterns
Focus by hour and weekday, so you learn when you do your best work.

Real reviews from the App Store and Google Play.

An amazing app to have all the things at one place! A timer, a todo and a room to study in with your friends. I’ve been wanting to study with my friends without using social media or distracting apps, and this is really it.

Best productivity app yet! Love how I can compare estimated vs actual time of my tasks and stay motivated in the focus rooms.

Franzi

Clean interface that is intuitive and awesome to use! I love how it keeps me focused with no distractions. The tracking feature is also great, with stats that’ll keep you motivated to keep up your focus streak!

The app has a relaxed and beautiful composition, soothing music, nice backgrounds… A nice and welcome feature to track your work versus the time spent… Rooms make it so you can study with other friends in the app, driving motivation and discipline. I am a believer and I’m sure you will be too.

I’ve been using the web version of this app for a while now, and it improved my productivity significantly. I use it daily. I quite enjoy the modification abilities and the ability to see my progress.

I’ve been using it for my tasks and setting up timers, and so far it’s been amazing. I like how it integrates the tasks and timer together. You can customise the app too.
