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 · Set one meaningful goal per day · Lock it in with a two-question validation · Mark it as achieved or resigned with reflection · Weekly history to track your progress · Home screen widget (small and medium) · Daily reminders to define and close your goal · Motivational quotes to keep you focused · 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.

KEEP TRACK OF WHAT HAPPENED Create a Paper Trail for anything you don’t want disappearing into texts, emails, screenshots, sticky notes, or your memory.
