  1. 5/5Upon First Time

    This is a well-designed App. Taken to the heart of our Latin language, traditional ecclesiastical life, and for people like me, very very good, and I think this will continue to be my guide for a long time, and the fact it works OFFLINE!!! GREAT!! Thank YOU!! I saw this off a Purely Catholic YT post, and I went straight to it, and I am grateful, God bless! And though he probably didn’t make it with this direct intention, I hope the creator of this app has it known to millions, Love the inclusion of the Latin!! Our language, surviving, and baptized. From the Romans, to the Catholics. Amazing, and hope we can all come to pray together by ways like the Latin, God bless the creator of the app and all who share it! Amen

  2. 5/5TLM Catholic Dream

    For this who cannot afford or find a 1962 Missal or Divine Office, or for those who wish to know the “canonical” Catholic prayers in Latin (with pronunciation), this app offers all of that was and more. It allows you to create a prayer schedule with the traditional prayers, and it provides the traditional Latin with its traditional English translations, side-by-side. Great for any Catholic, whether traditional, modern/progressive, reconciler, or just Catholic, as it provides a standard for Catholic prayers and devotions.

  3. 5/5The Best Traditional Catholic App!

    Thank you creating this app! It is well designed, user friendly, an invaluable spiritual aid, informative, focused without unnecessary distractions, and has a zero stress factor in using it. The Holy Spirit must have breathed inspiration upon you to develop such a divine tool for the laity! Thank you and God Bless you! Pax vobiscum sit.

  4. 5/5Incredible

    Clearly so much effort and attention to detail was put in to this and to have full access for free without ads makes it even better. Would highly recommend for any Catholic that is even remotely interested in traditional practices.

  5. 5/5Fr.

    INTROIBO is perfect - well, nearly perfect (for all my needs). When INTROIBO includes a Latin/SPANISH language option, it will have attained ultimate perfection. In all seriousness, this is a magnificent and most helpful App meant to help every devout soul; for the traveling priest, it is especially beneficial. I thank God for this gift.

  • 1.1.7

    Complete Divine Office from DivinumOfficium The entire weekly psalter rebuilt from authoritative liturgical sources. Every psalm now has its own proper antiphon for Vespers and Lauds. Capitula, hymns, and versicles change automatically with the liturgical season. Ascension texts during the post-Ascension period, Advent antiphons by week, Easter Alleluias throughout Paschal Time. 285 saints' feast propers with collects and antiphons. 521 Mass Propers Introit, Collect, Epistle, Gradual, Gospel, Offertory, Secret, Communion, and Postcommunion for every feast and feria throughout the year, all imported from DivinumOfficium in Latin and English. Three Sets of Rubrics Choose the 1962 rubrics, the 1955 reforms, or the pre-1955 Tridentine rubrics. Each has its own liturgical calendar with proper feast rankings and precedence rules computed for 2024–2030. Liturgical Calendar A pre-computed ordo determines the correct office and Mass for every day, resolving temporal and sanctoral conflicts, tracking commemorations, and assigning liturgical colours.

With the full psalms, lessons, and responsories in side-by-side Latin and English. 67 traditional prayers.

Polished the Mass Propers and Office prayers: corrected spelling, removed stray formatting marks, and fixed the bilingual section headings so the English title sits centered beneath the Latin. Plus, assorted calendar and Office corrections from your feedback. Thank you for praying with Introibo.
