What is it?
Captures QR attendance for events, classes, and teams; stores data locally during outages and turns it into reports later.

Schools, clubs, event teams, and small organizations.
Technical architecture
Built with a React/TypeScript UI, IndexedDB data layer, PWA setup, and Excel-friendly export flow.
