TradeApp - Panini World Cup
A web app to manage and trade Panini stickers for the 2026 World Cup — track your collection, swap duplicates with friends, and complete your album.
TradeApp is a full-featured web companion app for the FIFA World Cup 2026 Panini sticker album. Users register with a unique username, then digitally track their collection across all 980 stickers — organized by 12 groups, 48 national teams, and 14 exclusive Coca-Cola cards. The app automatically identifies missing and duplicate stickers, and generates shareable lists or PDFs to coordinate trades. A built-in friend system lets users connect via @username or QR code, and the app calculates optimal trade matches between friends in real time — showing who can give what to whom. Progress is visualized through a stats dashboard with per-group breakdowns, completion rings, and team-level tracking. The app is installable as a PWA, syncs across devices via Firebase, and includes a WhatsApp integration for sharing trade proposals. An admin panel allows real-time management of global announcements and popup campaigns with engagement analytics.
