Life Capsule

Life Capsule is a fully offline Android time-capsule app that helps you seal a private message for your future self. Write a title and message, choose a mood and capsule color, then set an unlock date and time that is at least one minute ahead and within twenty years. Before the unlock moment arrives, the sealed message stays completely hidden on every screen, with only the title, mood, countdown, and schedule visible. When the capsule becomes ready, a long-press open gesture with a short built-in animation reveals the text, which can then be copied or archived. Everything is stored only on the device with SharedPreferences, with no accounts, ads, analytics, cloud sync, or network features, making it suitable for calm personal reflection and Google Play distribution as a private utility.
