Technical Implementation
Offline-First Architecture
Built with SQLite for complete offline functionality. All data operations (CRUD) work without network connectivity. Database schema includes cards, stamps, rewards, and categories with proper indexing for fast queries.
Native Mobile Performance
Flutter framework ensures native performance on both iOS and Android. Compiled to native ARM code, providing 60fps animations and smooth user experience across all devices.
Barcode Scanning Engine
Integrated mobile_scanner for real-time camera-based QR code and barcode recognition. Automatic card detail extraction and validation. Supports multiple barcode formats (EAN, UPC, Code128, QR, etc.).
Privacy by Design
Zero network dependencies. No analytics, tracking, or cloud services. All data encrypted at rest using platform-native security. No data leaves the device under any circumstances.
