Folheto da Santa Missa dos Domingos is an Android application designed to help users follow along with the Sunday Mass. The app features the brochure of the Mass, which is available in PDF format and has been programmed into the app. This means that users can access the brochure without an internet connection, making it a convenient tool for people on-the-go.

The app provides the order of the Sunday Mass, including variations in music and homages to Saints depending on the region. Since the first Mass was celebrated in 1500 and is in the public domain, there are several websites where the brochure is available for free in PDF format. The app is primarily intended for users in the Northeast and North regions of Brazil, as well as some cities. The app will be updated every month to ensure that users have access to the latest version of the brochure.
