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. FOUR APPS, ONE DIARY — MOVE NOTES WHEN YOU WANT Native on iPhone, iPad, Apple Watch and Mac, and one purchase covers all four. Each app keeps its own encrypted library on that device, and there is no automatic sync. To move notes, bring two devices close, pair once with a 6-digit code and tick what to send — straight over your own Wi-Fi, with no server and no internet connection needed. Anything captured on the watch waits in a sync queue and reaches the iPhone even when you are offline. 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 12. Transfer between devices: bring two devices close, pair once with a 6-digit code, tick the notes to send — over your own local network, with no server in between Download free — your first three entries are free to write; a one-time purchase then unlocks unlimited writing, forever. iPhone, iPad, Apple Watch, Mac, 15 languages.

Verdict
The clearest difference is rating: OffMemory at 5.0 against Envision AI's 4.2. OffMemory also leads on update cadence (every 4 days vs every 5 weeks) and device support (5 vs 2). Envision AI's advantage is in-app purchases (none vs 1) and ratings volume (596 vs 1). On price, ads and iOS requirement there is nothing between them.
