Mobile Applications (iOS & Android)

OS Share Sheet Receiver#

LaterBox integrates directly into iOS and Android system share sheets:

• iOS Share Extension: Native Swift extension that captures URLs from Safari, YouTube, Twitter/X, and Reddit without opening the full application.
• Android Intent Receiver: Listens for android.intent.action.SEND with MIME type text/plain, performing immediate background SQLite writes.

Biometric Security & Vault Locks#

• Supports Face ID / Touch ID on iOS and BiometricPrompt on Android.
• Allows users to lock private collections or the entire vault behind biometric authentication.

Mobile Offline Caching#

• Articles and metadata are cached in local SQLite.
• Extracted hero images are stored locally using flutter_cache_manager with automatic LRU cache eviction.
