The application stands out by offering full Universalis content for every day of the year without any need for internet connection. It includes features such as scripture readings from different versions like NAB (USA), ESV (Great Britain), and Jerusalem Bible (rest of the world). Additionally, it combines daily Mass readings with the Order of Mass in its 'Mass Today' page.

Designed for Catholics seeking spiritual enrichment through regular prayer and reflection, Universalis serves both personal devotion and educational purposes. Its offline functionality ensures uninterrupted access to essential texts regardless of location—a valuable asset for travelers or those residing in areas with limited connectivity.
