Not because they didn't work hard, but because their tools fight them: a to-do list in one app, a calendar in another, a Kanban board in a third, and an AI chat in a fourth. Nothing talks to anything. Kaizen brings it all into one app that you actually want to open. → TIME-BLOCK YOUR DAY, NOT JUST LIST IT Drag tasks straight onto your calendar. See your real day — to-dos AND time blocks — side by side on a split screen (iPad/large screens). No more "I have 17 to-dos and 6 hours, what now?" — Kaizen shows you when, not just what. → AI THAT ACTUALLY KNOWS YOU You can use Kaizen's build in AI assistant or work with frontier models through MCP. Set persistent instructions ("Be blunt", "Push me on my side project", "Cut me slack on Fridays") and the AI shapes itself around you instead of you adapting to it. Brain-dump out loud, get a structured plan back. → KANBAN WHEN A LIST ISN'T ENOUGH Every project gets a board view. Drag tasks through Backlog → Doing → Done. Perfect for side projects, course work, and creative work where a flat list doesn't fit. → LIFE TIERLIST: SEE WHAT ACTUALLY MATTERS Hidden behind a long-press on the calendar icon: rank the areas of your life — Career, Health, Family, Learning, Side Project, ... — into a visual hierarchy. When you don't know what to work on, your tierlist answers for you. No other planner does this. → MAKE IT YOURS — REALLY YOURS Backgrounds per page. Custom fonts, sizes, icons. Opacity and blur per element. Custom colors. Windowed mode on larger devices. Most planners give you "dark mode and three theme colors." Kaizen gives you a workspace that feels like it was built for your brain. WHO IT'S FOR • Employees juggling work, life and a side project • Founders and freelancers who can't afford a messy day • Students whose calendar and homework live in different worlds • Anyone who's tried five planners and bounced off all of them WHAT YOU GET WITH UNLIMITED - Unlimited tasks, folders, and task lists - Calendar with day, week, month views - Drag-and-drop time blocking - Kanban board per project - Habit-style recurring tasks and reminders - iOS, Android, and Web — synced - Life Tierlist - Deep customization (backgrounds, opacity, blur, custom fonts) - Import/export your data anytime AI UNLOCKS - Kaizen AI with persistent instructions + MCP for Claude/ChatGPT - Speech task creation WHY "KAIZEN" Kaizen (改善) is the Japanese practice of getting 1% better, every day. Not a productivity hack. A way of building a life that compounds. START TODAY Spend 60 seconds importing your existing tasks. Block tomorrow morning. Notice the difference by Friday. Have an idea? Tap "Suggest a feature" in settings — we read every one. ## Kaizen Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/88/71/72/887172b7-9fe9-de5b-910d-a0d82978b9b7/1.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0e/b1/e9/0eb1e9a5-5068-f72b-2963-26798d1f1882/2.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/ab/76/31/ab763156-783b-962f-db55-b39a9d9a8bdf/3.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/63/b3/97/63b39729-aa68-727a-a8b9-c9f1b520ce86/4.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/fd/d8/f7/fdd8f70d-9868-78ea-072c-f276d0bef3d8/5.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/8b/ce/ac/8bceac94-01cf-6052-29dc-8d9d69cea26c/6.png/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/f7/5c/83/f75c8374-7fac-a2bc-7958-c898259a8d86/7.png/1242x2688.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/73/cf/e0/73cfe020-1e5f-581b-9eeb-8fe032b5e835/8.png/1242x2688.png) ## Kaizen Rating Breakdown in United States - 5 stars: 0 (0%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 1 (50%) - 1 stars: 1 (50%) ## Kaizen Reviews in United States ### **--- "Not ready" I’m always baffled by these new apps that feel justified in charging people before they’re even ready too. You have a ton of work to do with glitches. I normally do not write reviews but the fact that so many feel the need to overcharge or even charge at all is ridiculous. -- Jaranda82, 2026-03-19 [View all Kaizen reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Kaizen In-App Purchases | Item | Price | |------|-------| | Kaizen Unlimited | $47.90 | | Kaizen AI | $14.99 | | Kaizen Pro - Lifetime | $179.00 | | Kaizen Pro - Annual | $39.99 | | Kaizen Pro - Monthly | $3.99 | ## Apps Similar to Kaizen - [TaskerPlan - Tasks & Habits](https://apptail.io/app/taskerplan-tasks-habits-qhum/united-states) - [TypeAce](https://apptail.io/app/typeace-rDEm/united-states) - [Habit AI: Günlük Takipçi](https://apptail.io/app/habit-ai-gunluk-takipci-OMeu/united-states) - [Kaizen: ToDo & Productivity](https://apptail.io/app/kaizen-todo-productivity-jOeu/united-states) - [Daily Planner Task List Bunny](https://apptail.io/app/daily-planner-task-list-bunny-SAIu/united-states) - [Daily habit tracker - MyRecap](https://apptail.io/app/daily-habit-tracker-myrecap-HDxv/united-states) - [Minima Do - Voice To-Do List](https://apptail.io/app/minima-do-voice-to-do-list-ivEv/united-states) - [TaskManage Pro](https://apptail.io/app/taskmanage-pro-xIVv/united-states) - [Prism — Focus & Screen Time](https://apptail.io/app/prism-focus-screen-time-mflx/united-states) - [Daybase — Трекер Привычек](https://apptail.io/app/daybase-treker-privycek-rrwx/united-states) ## Kaizen Available In - [United States](https://apptail.io/app/kaizen-tasks-calendar-qfXv/united-states) - [Canada](https://apptail.io/app/kaizen-tasks-calendar-qfXv/canada) - [Australia](https://apptail.io/app/kaizen-tasks-calendar-qfXv/australia) - [Switzerland](https://apptail.io/app/kaizen-tasks-calendar-qfXv/switzerland) - [Cyprus](https://apptail.io/app/kaizen-tasks-calendar-qfXv/cyprus) - [Czechia](https://apptail.io/app/kaizen-tasks-calendar-qfXv/czechia) - [Algeria](https://apptail.io/app/kaizen-tasks-calendar-qfXv/algeria) - [Spain](https://apptail.io/app/kaizen-tasks-calendar-qfXv/spain) - [Croatia](https://apptail.io/app/kaizen-tasks-calendar-qfXv/croatia) - [Iceland](https://apptail.io/app/kaizen-tasks-calendar-qfXv/iceland) - [Japan](https://apptail.io/app/kaizen-tasks-calendar-qfXv/japan) - [Sri Lanka](https://apptail.io/app/kaizen-tasks-calendar-qfXv/sri-lanka) - [Luxembourg](https://apptail.io/app/kaizen-tasks-calendar-qfXv/luxembourg) - [Madagascar](https://apptail.io/app/kaizen-tasks-calendar-qfXv/madagascar) - [North Macedonia](https://apptail.io/app/kaizen-tasks-calendar-qfXv/north-macedonia) - [New Zealand](https://apptail.io/app/kaizen-tasks-calendar-qfXv/new-zealand) - [United Arab Emirates](https://apptail.io/app/kaizen-tasks-calendar-qfXv/united-arab-emirates) - [South Africa](https://apptail.io/app/kaizen-tasks-calendar-qfXv/south-africa) - [Armenia](https://apptail.io/app/kaizen-tasks-calendar-qfXv/armenia) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
