A focus app that does the boring parts for you

Kaizen keeps time, tracks where it goes, and puts other people in the room with you. Here is everything inside, free and Premium.

Pomodoro timer

The timer at the center of it all

Four presets out of the box, or set your own. Classic runs 25 minutes of work, 5 short, 15 long, across four sessions. Quick is 15/3/10. Extended is 50/10/30. Long Focus is 90/15/30. Custom sessions run from 5 to 180 minutes. Or pick Stopwatch in the timer settings and let focus count up.
  • Fully adjustable
    Work and break lengths, sessions before a long break, auto-start, all yours.
  • Stopwatch mode
    Focus until you are done, then Finish. Breaks stay the length you set. Free.
  • Background accurate
    Keeps perfect time with the screen off, then notifies you when a session ends.
  • Immersive mode
    Hide the header and tab bar for a clean, single-purpose screen.

App blocking

Block the apps, not the notifications

Block the apps that pull you away while you focus, or right away with Block now. You can also block apps on a schedule, even with Kaizen closed. On iPhone, iPad, and Android.
  • On with the timer
    Blocking starts and stops with your session, and breaks always lift it.
  • Three levels
    Normal is free. Premium adds Strict, which holds through a pause, and Locked, which runs the session to the end.
  • Nothing leaves your device
    No Accessibility service on Android, and on iPhone and iPad Kaizen cannot even see which apps you picked.

Focus Rooms

Body doubling, built in

Study alongside others in real time, the camera-free version of body doubling. See each member's status and the tag they are focusing under at a glance. Join any room for free, public from the list or private with a code, or host your own private room for up to 4. Premium lets you make rooms public, grow them to 50 people, and share the task you are working on.

Tasks

Tasks that track their own time

Capture anything into the Inbox in one line, then plan the ones you commit to. Up to 7 tasks on the To Do list free, with priorities and due dates. Make one active, focus, and the minutes log themselves. Premium removes the limit.
Inbox
Get a thought down now, decide what it is later. No limit on captures.
Due dates
All-day or a specific time, with a reminder from the due time to a week ahead.
Subtasks
Break work down and reorder it. Free on every plan.
Logbook
Completed work is archived and searchable, not deleted.

Habits

A habit tracker the timer feeds

Up to 5 habits free, unlimited with Premium. Check-off habits take one tap. Focus-time habits carry a minute target and complete themselves while your Pomodoro runs, the same way tasks track their own time. Streaks follow your schedule, and a skipped rest day never breaks the chain.
  • Timer-fed
    Every work-session minute counts toward the habit you picked on the timer screen.
  • Forgiving streaks
    Schedule-aware streaks with skips, open days, and honest backdating.
  • Consistency, not vibes
    A percentage and a trend line tell you whether a habit is building or slipping.

Themes

Set the mood, then get to work

Start with the free selection, or get the full library with Premium. Switch between cozy illustrations, real photography, and gently animated scenes whenever the moment calls for it, and expect new ones to keep turning up.
  • Six collections
    Lofi illustrations, nature photography, city, cozy, space, and minimal.
  • Some of them move
    Animated backgrounds loop quietly behind the timer. Some are free to try, the rest come with Premium.
  • Always something new
    Fresh scenes join the collection regularly, so the picker is never the same for long.
  • Your own background
    Drop in your own photo behind the timer. (Premium)

Focus music

A soundtrack for deep work
