BRAVO.I am a Lector and am very familiar with the official Lectionary of the Catholic Church. Universalis always gets the Calendar, Readings, and Mass prayers correct. I use Universalis “Readings at Mass” and “About Today” every day for my personal study and devotion. In addition, when attending Mass at a church where there are no full Missalettes, I use the “Mass Today” and “Order of the Mass”: it is always right on the mark for the entire readings and prayers for the Mass!I also like the ability to quickly go to any day of the Liturgical year and see the Feast/Memorial of the Saint of that day. Universalis has already added the brand new Feast “Mary the Mother of the Church” for the Monday after Pentecost!Praying the Liturgy of the Hours is somewhat complex for the average lay-person. Universalis makes it simple. The translations are different than some Breviaries, so may not be as useful for group recitation if all do not have the App. But the essence of each prayer is the same. May not be 100 pct perfect, but the ability to pray the LOH anytime, anywhere on your mobile device is literally a God-send. NOTE: to get the correct readings and calendar for your Diocese - it is important to go to the settings and select the local liturgical calendar for your country / region.For instance, in the USA, 6 Diocese celebrate The Ascension on the Thursday; the remainder celebrate on the Sunday. The Universalis settings options get it right.
