About

OneNext

Read full description

Not a to-do app. A starter. OneNext is built for getting started, not managing endless lists. When your to-do list grows, choosing what to do first can freeze you. OneNext removes the noise and guides you to one small next step. What OneNext does • One Next Step: Only one item on screen—no overwhelming lists. • Done / Later: Two choices to reduce friction. • AI “first step” breakdown: Turns vague tasks into a clear 5-minute action. Internet connection required for AI breakdown. • Make it smaller: Break it down again when it feels hard. • Keep your wins: Track what you did, not what you didn’t. Just one next step. Start small. Keep moving.

OneThing

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.
