The task is big. Your first step doesn’t have to be. Just Start helps you begin the task you keep putting off. Describe what feels hard to start, find one small action, and take it into a short focus session. MAKE THE FIRST STEP SMALLER Ask the app’s AI for a concrete first step for your own task. Still feels like too much? Ask for a smaller action. If AI is unavailable, you can write your own step or use the timer directly. START WITH TWO OR FIVE MINUTES Begin a short session without answering a survey. Pause when you need to. Longer focus and break presets are available when you want more time. SUPPORT WHEN YOU WANT IT Choose visual timers and ambient sounds. Pro adds more sound options, mixing, and optional AI check-ins. These check-ins are automated messages, not a live person working beside you. KEEP A LITTLE MOMENTUM See your focus history and progress. Return to a recent task or use a routine for something you do regularly. Optional account sync is available; an account is not required to start. START FREE The free app includes up to three focus sessions and three AI task requests per day, core progress tools, and three ambient sounds. Pro adds unlimited focus sessions and expanded support. AI requires internet access and is subject to service limits. PRIVACY The timer and local progress work offline. When you request AI help, your task and relevant context are sent through our server to our AI provider. Optional account sync sends account and synced app data to our cloud service. Read the privacy policy before sharing sensitive task information.

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.
