Why I Built This
Event venues suffer from severe cellular congestion and dropped Wi-Fi under crowd loads. Standard web forms freeze or drop responses when attendees submit surveys at interactive booths.
How It Works
1. Android TV Local Persistence Queue
Built with Flutter for Android TV touch displays. Every attendee submission writes immediately to a local SQLite journal. A connectivity listener detects stable connections and flushes queued JSON records in atomic batches.
Results & Numbers
Ran continuously for 8 hours on-site during a high-density live event with zero dropped responses and zero crashes.
8 Hours
Continuous offline operation during live event

Dropped survey submissions or app crashes
Retrospective:Adding an automated USB export fallback would give event coordinators even greater peace of mind during total network blackouts.
