End your day feeling done — not buried. 88% of people go to bed feeling unaccomplished. 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?

DisabilityLog

Document what your disability looks like - every day. DisabilityLog is a private daily journal for people applying for or maintaining SSDI, SSI, Long-Term Disability, or VA benefits. Record daily abilities, good and bad days, appointments, medications and personal notes. Create a PDF to review with your attorney or representative. Seven daily reference categories organize selected topics from SSA Form SSA-3373: personal care, meals, housework, going out, social, concentration, and stress. They are not a complete copy of the form, and App ratings are not official SSA scores. PRIVATE LOCAL RECORDS - No account, login or automatic record upload. - All daily logs, symptoms, appointments, and medications stored locally on your device using SwiftData. - PDF generation runs on-device with PDFKit. Reports never leave your phone unless you choose to share them. - No developer-operated record server; we do not receive your medical history through the app. WHAT YOU CAN DO FOR FREE - Daily check-in (function level 0-10 + day type + general notes) for up to 30 saved entries. - Home 7-day function trend and Insights 30-day ratio. - Up to 3 medical appointments and 3 medications. - Color-coded Good Day / Bad Day calendar. - Free PDF and Markdown summaries of all saved logs for the active claim. - Home screen widget, Face ID / Touch ID app lock, daily check-in reminder. - Read-only SSA-3373 category reference guide. UPGRADE TO PRO TO UNLOCK - Unlimited daily logs - no 30-entry cap. - All seven daily reference categories. - Longer-window Good Day vs Bad Day analysis. - Attorney or ALJ-ready evidence PDF, generated on-device. - Unlimited medical appointments and medications, including SSA Consultative Exams, with side effects. - Daily symptom sliders: pain, fatigue, cognitive, mobility, mood. - Activity attempted and activity avoided fields. - Sleep hours, quality, and daytime nap tracking. - Function and symptom trend charts. - Full structured CSV export of all log entries. WHO THIS IS FOR - First-time SSDI or SSI applicants told by their attorney to keep a daily diary. - Applicants denied at initial review who need stronger evidence for reconsideration or an ALJ hearing. - Long-Term Disability claimants whose insurance company is challenging the claim. - VA disability claimants filing or appealing a rating decision. - Continuing Disability Review (CDR) preparation. - Long COVID, fibromyalgia, chronic fatigue, mental health, and other chronic-condition applicants. WHO THIS IS NOT FOR - People wanting an eligibility checker that says whether they qualify. - People wanting AI to write their function report. - People wanting their data synced to an SSA account or law firm portal. DisabilityLog is a personal documentation tool. It does not provide legal or medical advice, determine disability eligibility, communicate with SSA or any insurance carrier, or auto-fill any government form. The app does not file forms on your behalf. Ratings are personal assessments; saved categories may include unedited defaults. PRO OPTIONS - Annual subscription, with an introductory trial only when Apple confirms eligibility and an applicable offer. - Lifetime: one-time purchase, when available from Apple. Existing monthly purchases remain supported. Current localized prices and offers appear in the app. Subscriptions auto-renew until canceled. Renewals occur within 24 hours before the period ends unless canceled at least 24 hours prior. Payment is charged to your Apple ID. Manage or cancel in Settings > Apple ID > Subscriptions. Apple handles refund requests under its policies and applicable law.
