Gosc is an iPhone application developed by CENTERSIS TECNOLOGIA DE INFORMACAO E ASSESSORIA EDUCACIONAL LTDA. It aims to streamline access to Masonic Lodge information, allowing users to view their data, check upcoming birthdays in their lodge and others, and access the Fraternal Guide. Users can discover active lodge members, search for brothers, view the Bulletin, and stay informed about all Masonic events.

Within the app, users can initiate phone calls, send SMS, or emails to the displayed brother in the Birthdays and Fraternal Guide sections, promoting communication among lodge members. Additionally, users can search calendars, mark attendance for events, and view Masonic Identity details.
