STOP DROWNING IN YOUR TO-DO LIST You don't have a productivity problem. You have a clarity problem. Too many tasks, too many apps, too many choices — your brain freezes before you even start. Sixthings fixes this with one constraint: 6 priorities a day. No more. When you can only pick 6, you're forced to decide what actually matters. That decision — repeated daily — changes everything. BUILT FOR OVERWHELMED BRAINS If you've tried every planner, every system, every app — and still feel behind — Sixthings is different. It doesn't give you more tools. It takes them away. - Only 6 tasks. Ever. The limit is the point. - Priority #1 stays locked at the top. Do it first. - Evening planning: choose tomorrow's 6 tonight. Wake up clear. - Incomplete tasks roll over automatically — no guilt, no lost work. MEET IVY — YOUR PATTERN MIRROR After a few days, Ivy starts showing you what you actually do vs. what you say matters. "You've put 'exercise' on your list 12 times. You've completed it once. It's always #5 or #6. What's really going on?" Ivy isn't a chatbot. Ivy is a mirror. It shows you the gap between your intentions and your actions — the gap most people never see. WHY THIS WORKS FOR ADHD & OVERWHELM → Decision paralysis? You only get 6 slots. Choosing is fast. → Task initiation? #1 is highlighted. Start there. Just that one. → Losing track? Patterns show you exactly where your energy goes. → Guilt spirals? Rollover is automatic. Tomorrow is a fresh start. CORE FEATURES • 6-task daily limit — the constraint IS the product • Drag-to-reorder priorities • Streak tracking (consecutive days completing #1) • Ivy tab — your patterns, insights, and honest reflections • Weekly report with AI-powered analysis • Custom Vibes to tag focus areas • Evening planning mode (6 PM+) • iCloud sync across devices • Beautiful dark design — no visual clutter SIXTHINGS FOCUS (PREMIUM) • Daily Ivy insights (vs weekly for free) • Deeper pattern breakdowns • Morning reminder to start with #1 • Support independent development Sixthings won't do the work for you. But it will help you see yourself clearly enough to stop spinning and start choosing.
