The Kaizen timer running a focus session
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

Pick the apps that pull you away and they stay blocked while a work session runs. Breaks unblock them by themselves. A free Block now button blocks until you turn it off, with or without the timer, and you decide in advance whether the block screen offers a way through. Three apps free, on iPhone 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 phone
    No Accessibility service on Android, and on iPhone Kaizen cannot even see which apps you picked.

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

Every still background is free. 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. Most are free, a small number are 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
