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.

OneThing cuts through the ADHD fog and shows you one thing at a time. It's an ADHD focus & task planner. You have tasks in Google Tasks, events in Google Calendar, emails in Gmail, reminders in Apple Reminders, items in Todoist — and a brain that freezes when choosing where to start. OneThing reads all of it, scores by urgency, and hands you a single swipe card: the one thing to do right now. HOW IT WORKS Swipe right to commit and mark done. Swipe left to defer. Swipe up to delete. Swipe down to pin as your Do Now. Each swipe brings the next card — no lists, no overwhelm. WHAT YOU GET • Decision queue that merges calendar events, tasks, and emails into one prioritised stack • AI assistant you can voice-ramble to — it turns your thoughts into tasks and actions • Google Calendar, Google Tasks, and Gmail sync — see your whole day without switching apps • Apple Reminders sync • Todoist sync • Do Now mode: one thing, front and centre, for the next hour BUILT FOR ADHD No lists. No folders. No endless settings. Just one card, one choice, one tap. PRIVACY OneThing reads your calendar events, tasks, and email metadata (subject, sender, date). We never read email bodies without your explicit opt-in. Your data is never sold and never used for advertising.
