Private Journal & Mood — Biometric, Encrypted, Offline (SwiftUI + Apple Watch)
Private Journal & Mood is a complete, App-Store-ready SwiftUI app for iOS 16+ with an Apple Watch companion (watchOS 9+). It's built around privacy that's actually real: - Two real security layers. A Face ID / Touch ID lock (with passcode fallback) gates the app, and every entry's text is encrypted at rest with CryptoKit AES-GCM. Only ciphertext is written to disk; the key lives in the Keychain, this-device-only, never synced or backed up. - 100% offline. No network code, no accounts, no analytics, no third-party SDKs. Ships with a correct `PrivacyInfo.xcprivacy` (declares no tracking, no data collection). - Beautiful, native UI. Light and dark mode on every screen, a mood calendar heatmap, mood trend charts (Swift Charts), streaks, smooth animations (Reduce Motion respected), Dynamic Type, and app-switcher blur. - On-device sentiment via Apple's NaturalLanguage — mood tags are the primary signal. - Apple Watch companion for quick mood logging + a streak glance, with a WidgetKit complication. The watch never holds entry text or the key (WatchConnectivity only). - Reskin in under an hour. Colors, strings, app name, and icon are centralized. Full Re-Skin Guide, Documentation (HTML), unit tests, and seeded demo data included. Positioned as a private journaling & mood-logging app — not a medical device.
