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.

Decidd turns a hard choice into a clear call. Big decisions get stuck in back-and-forth: too many options, too many "but what about...". Decidd gives you a simple, structured way through it. How it works: • Name your decision: type it or just speak it. • AI suggests the options you're weighing and the criteria that matter. • Rate how each option does on each criterion. • Set what's important with quick this-or-that comparisons. • Get a ranked result, a clear winner, and a short explanation of why. Why people like it: • Fast and focused: no clutter, no account, no sign-up. • Works your way: use the AI assist or do it all by hand. • Your data stays yours: decisions are stored on your device and synced privately through your own iCloud. No ads, no tracking, no analytics. Your Pathfinder to Lift-off.
