Our unqiue app for the traditional (1962) Missal and Breviary allows you to consult the Ordo everywhere and without a Wi-Fi/Internet connection after downloading.


The Ordo is an indispensable resource for clergy, sacristans, MCs and even the laity for properly following the daily calendar rules of the traditional Roman Missal and Breviary. This guide automatically applies the general rubrics of the missal and breviary to each liturgical day. So there's no need for you to look up the rubrics yourself!

Each daily entry includes the class of the day and its proper Mass, the color of the vestments, and lists the variable parts of the Mass and Breviary. [NB: an Ordo does not include the prayers or readings of the Mass.]


In publication since 1979, our printed Ordo is not only the most comprehensive edition available for the traditional Missal and Breviary, but also considered by many as the most accurate, year after year.


Other useful features of our Ordo include notes as when a Requiem Mass is prohibited, there's a special votive Mass option, and even pulpit announcements related to the liturgical year.

Our app also includes several appendices via a drop-down menu present on every entry page:

  • Explanation of abbreviations and signs

  • Excerpts of the Rubrics of the Roman Missal and Breviary

  • Concurrence/Occurrence table

  • Diocesan feasts for USA, Canada, Great Britain, Australia and New Zealand


We will also be rolling out several new features :

  • Screen swipe navigation for day-to-day entry
  • Listing of the proper Diocesan Feasts per country (already enabled for the USA) below the universal daily entry (see the daily entry pic above)
