App Description
The Catholic liturgical calendar. Every day of every year, with notes on saints.
Feasts and celebrations according to the General Calendar and the local calendars of the UK, the USA, Australia, New Zealand, South Africa, Ireland, and others. Features "About Today" pages giving more information about the saint of the day.
You get a free one-month preview of the Universalis pages, which contain the Readings at Mass (NAB translation for the USA, the new ESV for Great Britain, Jerusalem Bible in the rest of the world), the Mass Today (which combines the daily Mass readings with the Order of Mass) and the Liturgy of the Hours: Morning Prayer, the three daytime hours, Evening Prayer, Night Prayer, and the Office of Readings (scripture readings – United States: RSV. Elsewhere: Jerusalem Bible, with RSV as an optional add-on).
If you like what you see in the one-month preview, you can take out a monthly subscription to it or you can buy the Universalis app instead.
You can purchase or subscribe to audio for all the Hours (spoken in English), the Gospel of the day (Jerusalem Bible, spoken in English), or the daytime Hours (Terce, Sext, None) spoken in Latin.
