About

Kaizen

Features
Read full description

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.
