The availability of information about the Catholic church in the Special Province of
Yogyakarta is still limited. The lack of available media information makes it difficult for local and
out-of-town communities to get information about the location of the church where they want to
worship. The solution taken to overcome this problem is to build applications that can process
church data into useful information for the community. This application is an Android application
based on Location-Based Service technology and utilizes the Google Maps API, Firebase, and
Global Positioning System in its development. This application will make it easy for users to get
information about the name of the church, church address, church contacts, worship schedules,
church social media, church facilities, church photos, church maps, and the latest information.
