Kaizen is a minimalist focus and study companion for people who'd rather just get to work. FOCUS, ENFORCED Run Pomodoro-style cycles or a standalone timer. Focus Guard means leaving the app mid-session actually costs you — no silent pausing, no cheating the clock. EARNED PROGRESS Tasks can only be checked off after you've actually put focused time into them. Group tasks under goals, watch progress bars fill up, and let finished goals archive themselves — or mark a goal to repeat, so it resets and tracks how many times you've completed it. CAN'T DECIDE? SPIN. When you don't know what to work on next, let the spinner pick from your open tasks. SEE YOUR PATTERNS A weekly chart and a monthly heat-map calendar show where your focus actually went, day by day. Streaks and a simple XP/level system make consistency visible without turning it into a game. PRIVATE BY DEFAULT No account, no sign-up, no server. Every goal, task, and session lives only on your device. Nothing is collected, tracked, or shared — see the full privacy policy for details. Kaizen — 改善 — means constant, incremental improvement. That's the whole idea.

Your pet is only alive because you focused. Mochiverse is a focus timer with a pixel creature living inside it. Start a session, put the phone down, and your Mochi grows. Neglect it, and it doesn't. HOW IT WORKS - Hatch an egg. One of 5 species, chosen at random. - Pick 15, 25, 45 or 60 minutes, or set your own. - Focus. Your Mochi sleeps beside you and gains XP the whole time. - Finish and earn coins, food and a streak day. - Feed it, play with it, keep its health up between sessions. IT CAN ACTUALLY DIE Hunger, mood and health drain in real time, even while the app is closed. Let health hit zero and your Mochi is gone for good, into the Memorial Garden. It turns out nothing makes you come back tomorrow like a creature that needs you. 31 FORMS TO DISCOVER Every Mochi evolves through a branching tree, and the branch it takes depends on how you actually cared for it. Feed it well and it grows one way. Play with it and it grows another. Your Collection remembers every form you have ever reached. BUILT FOR REAL FOCUS - Live Activity on the Lock Screen and Dynamic Island. Check the timer without unlocking. - Home Screen widget with your pet, your streak and today's minutes. - Focus subjects. Tag sessions as Math, Work, Reading, whatever you like. - A daily reminder at a time you choose. - Ambient sound while you work: lofi, piano or rain. - Streaks, session history and per-subject stats.

Never lose a pet for good. - Pets decay 40% slower, so they need less babysitting. - 11 extra themes: sunset, aurora, sakura, midnight, galaxy and more. - 7 exclusive pet skins: golden, cosmic, mint glow and others. - Pro stats: weekly goals, deep charts and per-subject reports.
