CantiCristiani is a free mobile application available on Android developed by Michele Mammini that provides an extensive library of liturgical songs with guitar chords. The app offers a variety of features such as selecting favorite songs, searching for songs by religious period or liturgical moment, and changing the chord key. Users can also enable automatic text scrolling during performance, customize the display mode, adjust font size, and create personalized playlists for use during mass. Additionally, the app provides links to YouTube videos for listening to the songs, remembers the set key and user-defined tempo, and allows sharing of favorite songs and playlists across devices via email. A new feature recently added to the app is a section dedicated to daily readings. The app works offline, with the exception of syncing with the database. Users can also report errors in lyrics or chords, request new features, and recommend new songs to be added to the app.
