About

One Earthling

[Today] Today's serious business is doing a little less serious business. Go for a walk, try something you've never eaten, or just take a break. Try it, or skip it. Either is fine. However today turns out, you can still say: "Today was great." [Notes] Human memory has its limits. That's why we invented notes. A sentence, a photo—the little things you don't want to forget are the snapshots that make up a life. You can also seal a note and leave it in time's care. When the time comes, open it and see what your past self left behind. [Let Go] Some things don't need to stay in your hands. Write down a worry, something you never said, or whatever you want to say goodbye to. Send it on its way with a small ritual. No explanations, no questions asked. What's sent away isn't saved. [Fate] What humans can't figure out, leave to fate. Whether you listen to it is still up to you. No completion rates, no daily check-in streaks, and no one telling you how you ought to live. After all, a trip to Earth already comes with plenty to worry about. As for the rest, sometimes it's fine to let it be. An earthling. An ordinary day is still a day. —————— No separate app account is required. Supports English and Simplified Chinese. A continuous 168-hour full-feature trial starts on first launch. No subscription is required, and the trial never turns into a charge automatically. Monthly, annual and permanent options provide the same features. Monthly and annual subscriptions renew automatically and can be managed through Apple. Permanent access is a one-time purchase. Prices and billing periods are shown for your App Store region before you confirm with Apple. After confirmed expiry without an active purchase entitlement, you can still read existing notes, open due sealed notes, view the status of future sealed notes, and delete existing notes or sealed notes. Creating, editing and scene actions require active access. A permanent purchase does not automatically cancel an existing subscription; check your renewal status in Apple's subscription management.
