About

OneThing

Read full description

1Thing helps you cut through the noise and focus on what truly matters each day. The concept is simple: choose ONE important goal, lock it in, and give it your full attention. When you're done, close it with context — how much impact it had, how difficult it was. If you gave up, close it honestly and move on. ONE GOAL. NOT A LIST. Most productivity apps overwhelm you with tasks. 1Thing does the opposite — it forces you to ask: "What's the ONE thing that, if I do it today, makes everything else easier?" FEATURES Ā· Set one meaningful goal per day Ā· Lock it in with a two-question validation Ā· Mark it as achieved or resigned with reflection Ā· Weekly history to track your progress Ā· Home screen widget (small and medium) Ā· Daily reminders to define and close your goal Ā· Motivational quotes to keep you focused Ā· Beautiful, distraction-free design YOUR DATA. YOUR DEVICE. Everything stays on your iPhone. No accounts, no cloud, no tracking. Just you and your one thing. 1Thing — because less is more.
