"Tricolorii" serves as the official application for the national football teams of Romania, providing a comprehensive platform for supporters. Formerly known as "Fan Arena by FRF," the app has been revamped to offer exclusive content, real-time news, and interactive features. Users can engage with behind-the-scenes materials, communicate with players, and participate in competitions, all while staying up-to-date with the latest developments in Romanian football.

The application also acts as a guide for fans traveling to the European Championship in Germany, featuring maps of points of interest related to match locations. Users can purchase match tickets, buy merchandise, and engage in various fan activities, including quizzes and voting for player accolades. With its user-friendly interface, "Tricolorii" ensures that Romanian supporters remain closely connected to their national teams.
