Álbum de Cromos

Álbum de Cromos is a free app, developed by Cesko Design, to keep track of the 2026 World Cup and LaLiga 2026/27 sticker albums: mark the ones you have and the ones you need, scan an album page with the camera to detect the gaps, swap duplicates with other users via messages and play a quiz.

It is published on Google Play and also runs as a web app. The app is built with Capacitor on React and TypeScript, uses OpenCV.js to recognise stickers, and the server is a PHP and MySQL API. The landing albumdecromos.es, in plain PHP, presents the app and links to the store.
