OffMemory is a fully encrypted diary — your words stay on this device. Every note, title, photo and drawing is locked with AES-256, and the password is derived with Argon2id, so guessing it offline is expensive. No cloud, no servers, no ads. It opens and you write Layered materials, a restrained type scale, a hairline border instead of shadows, and light or dark following the system. Every touch target was audited for size and contrast — a journal that does not compete for attention: writing first, features second. Three things worth calling out 1. Second Vault: set a second, decoy password. Unlocking with it opens a separate space where your real journal is not visible — separate database, separate keys, separate media folders, not merely a hidden entrance. 2. Apple Watch: capture from your wrist, entries wait in a sync queue so nothing is lost offline, and you can lock the phone from your wrist. No new permissions, and the watch never keeps note text. 3. On-device summaries on Apple Intelligence devices: summarise, suggest a title or reflect. Nothing leaves the device. Key features 1. Password protection with Face ID; the app locks itself when it leaves the foreground 2. Recovery code: write it down once and your notes stay readable even if you forget the password 3. Per-note lock: one entry behind its own Face ID check, separate from the app lock 4. Time Capsule: a letter to your future self, sealed until the day you choose 5. Full Markdown toolbar with inline sizes and colours, folders, tags, favourites, moods and a writing calendar 6. Event date: date an entry by when it happened, separately from when you wrote it 7. Insights: a year of writing as a heat map, with streaks, active days and average length 8. Year in Review: a year on one page; the optional share card carries statistics only, never note text 9. Optional Spotlight index — titles only, off by default, never locked notes, never note bodies 10. Home-screen widget and Lock Screen control (iOS 18+) 11. Export to PDF, Obsidian-ready Markdown or mood CSV; an encrypted backup restores on a new iPhone Download free — your first three entries are free to write; a one-time purchase then unlocks unlimited writing, forever. iPhone, iPad, Apple Watch, 15 languages.
