Introibo is a prayer companion built for the traditional Catholic life. Designed for the Roman Missal and Roman Breviary, with full support for the 1962, 1955, and pre-1955 rubrics. Ad-free, offline, and without subscription. No accounts. No tracking. Just the prayers of the Church, always available. YOUR DAILY COMPANION The Hodie screen shows today's feast, the proper of the Mass, the Divine Office, fasting and abstinence obligations, the daily psalm, and the seasonal Marian antiphon, all computed from the traditional calendar. See the liturgical colour, the season, and countdown to the next major feast at a glance. Follow one of seven patron saints with daily practice checklists and streak tracking to build a habit of devotion. THE TRADITIONAL ROMAN MISSAL The entire Ordinary woven together with 574 daily Propers in their correct order, each with full English translations. Latin and English rendered side-by-side. Every rubric observed: 14 proper Prefaces selected for each season and feast. The Gloria appears only when the rubrics prescribe. The Credo on Sundays and major feasts. Psalm 42 omitted in Passiontide. Proper Tracts replace the Alleluia from Septuagesima through Palm Sunday. The Canon includes proper Communicantes and Hanc Igitur for the great feasts. The correct dismissal, Ite Missa Est, Benedicamus Domino, or Requiescant in pace, chosen automatically. Three distinct Masses for Christmas. The Requiem Mass with its proper texts. THE DIVINE OFFICE Pray all eight canonical hours: Matins, Lauds, Prime, Terce, Sext, None, Vespers, and Compline. The complete weekly psalter with individual antiphons. Proper capitula, hymns, and versicles change automatically with the season. 285 saints' feast propers with collects and antiphons. Three-nocturn Matins with Te Deum for Class I and II feasts. Seasonal hymns for Advent, Lent, Passiontide, Easter, and Christmas. Four Marian antiphons at Compline. Set reminders for each canonical hour. LITURGICAL CALENDAR Browse the traditional calendar month by month in list or grid view. Every day shows its Latin feast name with English translation, liturgical colour, and season. Tap a day for full detail: feast, colour, season, fasting obligations under your chosen discipline, and a link to that day's Mass. Share any day as a styled PDF. THREE SETS OF RUBRICS Choose your tradition. The 1962 rubrics, the 1955 reforms, or the pre-1955 Tridentine rubrics, each with its own calendar and feast rankings. The ordo resolves temporal and sanctoral conflicts, tracks commemorations, and assigns the correct liturgical colour for every day. FASTING AND ABSTINENCE Three penance disciplines: the 1962 norms, the 1917 Code of Canon Law (with Ember Day fasts, vigil fasts, and Saturday Lenten abstinence), and the stricter pre-Pius XII observance (with Advent fasting and no upper age limit). The app shows your next obligation day and spells out exactly what you can and cannot do. SEARCH Search across everything, prayers, Mass propers, Office hours, saints, and reference articles, from one search box. Diacritic-insensitive, so "miserere" finds "Miserére." Results link directly to the content. PDF EXPORT Share or print the Mass propers and calendar days as styled PDFs with parchment background and bilingual side-by-side layout, ready to take to Mass. 67 TRADITIONAL PRAYERS Build a personal prayer rule for morning, midday, and evening.

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. ### 5/5 — No Latin-Spanish *2026-07-16* So many updates and none for a upcomming Latin - Spanish speaking ### 3/5 — UX isn’t as good as could be *2026-06-06* Font size too small for some elements. Doesn’t change between dark and light theme with the system. Doesn’t allow texts to be copied. App still seems to be slow and sluggish sometimes. ### 5/5 — The Best Traditional Catholic App! *2026-05-21* 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. **Developer response:** Thank you so much for your support. There is much more to come, so we’re happy you have enjoyed it so far. ### 5/5 — Outstandingly Thoughtful and Comprehensive Catholic Lifestyle Companion *2026-05-19* This app offers it all: Mass, prayers, daily asceticisms, and tutorials. I am grateful for the hard work put into this piece of software that will, no doubt, help countless people nurture a love of traditional Catholic life. ### 1/5 — Perfect *2026-05-18* One of my constant complaints has been trying to figure out how to do more traditional penances and this app seems like it will help with that. I really wish you guys would outline what each set of fasting rules contains though. Like whats the differences between each of the three. Deo gratias! **Developer response:** Thank you for the support and the specific feedback. You’re right that the differences between the three disciplines aren’t laid out in the app, that’s something I’ll add in a future update. We really appreciate the helpful insight. Please let us know if there’s anything else you’d like to see! ### 4/5 — Good potential, but buggy *2026-05-18* Upping my starts a bit because the developers are working to fix the issues. This app has great potential but rather buggy. Not yet five starts, but I appreciate the effort **Developer response:** Update 1.1.5 will be out soon and should address all those concerns. The Missal and Office needed some help, yes, and hopefully all the bugs are resolved. This is our first app, so there will be some issues, but rest assured we’re working hard to fix them. ### 5/5 — I love it *2026-05-18, version 1.1.5* Love how simple it is to use, no login, no nonsense but so rich of material and everything you need. Thanks so much 🤍 ### 5/5 — TLM Catholic Dream *2026-05-17* 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. **Developer response:** Thank you for your support! We’re so glad that it has been helpful for you. Please let us know if there’s anything you would like in future versions. ### 5/5 — Upon First Time *2026-05-16* 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 **Developer response:** We’re so glad you enjoy the app. When we were designing it we specifically wanted it to be offline because that was something we wanted for ourselves. ## Frequently asked questions about Introibo ### What rubrics does Introibo support?
