Kaizen is a Pomodoro focus timer with a built-in app blocker that blocks distracting apps while you focus. Plan your day in a to-do list, build habits, and join study with me rooms for body doubling when you focus better with company.

POMODORO TIMER & STOPWATCH
A study timer and productivity timer for simple time management:
• Presets: Classic (25/5/15), Quick (15/3/10), Extended (50/10/30), Long Focus (90/15/30), or your own
• Focus 5-180 min, short breaks 1-60, long breaks 5-120
• Stopwatch: count up with no fixed end and finish when you're ready
• Auto-start the next session while Kaizen is open, until the cycle ends
• Keeps time in the background and notifies you when a session or break ends
• Immersive fullscreen focus mode showing only the timer

APP BLOCKER
Pick the apps that pull you away, like social media or games, and the app blocker blocks them while you focus:
• Blocked during focus sessions, open again on your breaks
• Block now: block them right away, until you turn it off
• An optional "Open anyway" button: you set the uses, the wait, and the time limit
• Premium: Strict mode keeps apps blocked while you pause; Locked mode also stops the session from ending early, except one emergency end a week
• Block up to 3 apps free, or any number with Premium
Uses Android's Usage access and Display over other apps settings, never an Accessibility service. Your app list never leaves your phone.

HABIT TRACKER
Build daily routines that stick with a flexible habit tracker:
• Check-off habits, or timed habits your focus sessions fill in
• Schedules: daily, set weekdays, or X times per week
• Forgiving streaks that don't punish a skipped day
• A consistency score and trend chart: building, or slipping?
• Backdate any missed day
• Reminders that follow each habit's schedule

THEMES & LOFI FOCUS MUSIC
• 60+ backgrounds across Lofi, Nature, City, Cozy, Space, and Minimal, including animated ones
• Lo-fi study music, ambient, nature sounds, white noise, and classical to help you concentrate
• Tracks you play are saved for offline listening

STATISTICS & STREAKS
• Daily, weekly, and monthly focus breakdowns
• Focus by hour and by weekday: find your most productive time
• A focus trend chart to track your concentration over time
• Focus by tag: tag each session as Study, Work, Reading, and more to see where your time goes
• Session history you can re-tag or clean up
• Daily focus streak tracking with milestone colors

TO-DO LIST & TASKS
Your to-do list meets a work timer, so you see where your time goes:
• Jot a task down in one line now, sort out the details later
• Priorities, due dates, and push reminders
• Today, Tomorrow, and Overdue badges keep deadlines in view
• Pick a task to focus on and the timer logs your minutes to it
• Subtasks and time estimates with visual progress

FOCUS ROOMS: STUDY WITH ME
Study with friends or alongside others in a virtual study room, no camera or mic:
• Join any room free, or host a private one and invite up to 3 friends with a link
• See who's inside and whether they're focusing before you join
• Live timers for every member, plus the focus tag they picked
• Premium: host public or bigger rooms (up to 50 people), and share your task for accountability

• Remote workers and freelancers who need time for deep work
• Writers and developers who want a stopwatch to protect their flow state
• People with ADHD who focus better with structure and company
