一息 Once

一息 Once is a quiet habit app for iPhone and Apple Watch. Choose one small thing, connect it to a moment that already happens, and reduce it to a step you can do even on a low-energy day: After dinner, walk for 5 minutes. Before bed, read one page. Add up to five habits. Each day only asks whether you did the smallest step. There are no streak scores, points, rankings, ads, or social pressure. Home Screen, Lock Screen, and Apple Watch complications keep the next step visible. Mark today on iPhone or Apple Watch, undo an accidental tap, or add yesterday when you really did it. Archive habits you are pausing without losing their history, and bring them back whenever you are ready. Trail shows a calm 13-week view of your progress. Your phone and paired Apple Watch merge records on device. There is no account, no cloud service, and no analytics. To move to a new phone, export a local .yixi file and import it yourself. Do one small thing. Then stop.
