RSA+ is the official application of the Réseau Sports Adultes, designed to facilitate communication and organization for players, managers, and referees. Available for free on iPhone, this app allows users to manage one or multiple teams, confirm attendance, and communicate effectively with teammates. Its synchronization across iOS and web platforms ensures that users remain connected no matter where they are.

The app features two primary modes: Player Mode and Manager Mode. In Player Mode, users can confirm their presence at games, receive updates, chat with teammates, and quickly access schedules and results. Manager Mode provides additional capabilities, such as managing team rosters, sending attendance reminders, and finding replacements. With tools for scheduling, messaging, and player management, RSA+ enhances the overall experience of participating in adult sports leagues.
