Ordo 2020: Mobile App

For Android devices

Note & Substitute for Apple Devices App


Take the Ordo for the traditional (1962) Missal and Breviary where ever you go without having to carry a book (or requiring a Wi-Fi/Internet connection after download). This digital version offers the same great info from our printed Ordo, but is completely mobile and always available on your smartphone!


Officially titled in Latin as Ordo Divini Officii Persolvendi Missaeque Sacrificii Peragendi (Pro Anno Domini 2020), the Ordo is an indispensable resource for clergy, sacristans, MCs and even the laity for properly following the daily rules of the traditional Roman Missal and Breviary.

The Ordo takes all of the various classification rules listed in the Rubricae Generales sections of the missal and breviary and applies them automatically 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: the ordo only provides the rules for setting up the missal and breviary; it does not include the prayers or readings of Mass.]


Other useful notes are also included, such as when a Requiem Mass is prohibited, special votive Mass options, and even pulpit announcements related to the liturgical year.

The 2020 Ordo mobile app 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

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

Android app: $4.99 via Google Play Store.

How to use the Ordo app on Android devices

Note & Substitute for Apple Devices App

Unfortunately, we will not be able to provide a 2020 Ordo mobile app for Apple (IOS) devices. Apple has rejected our submission of the app, despite repeated appeals. This rejection from Apple came as a complete surprise to us, as we've successfully offered the Traditional Ordo App for IOS devices since 2018.

We will be offering a dynamic Ebook soon for Apple users.

In the meantime, to ensure that those with Apple devices can still consult the 2020 Ordo "on the go", we are offering a dynamic PDF version that runs until March 8, 2020 inclusive to December 2020 for just $2.00. It includes the appendixes for the USA, Canada, UK, Australia and New Zealand, as well as the preliminary informational sections.

We understand that this is not an ideal remedy and greatly apologize for this inconvenience, but hope that the PDF will at least bridge the gap until a better solution is found.

Testimonies about the Ordo App


Love it! I use it to pray the Office every day! It works great. It’s available in several languages. And it contains a whole bunch of extra prayers. Great app that is a must have for me! Jongleur_de_Dieu

Useful Ordo

I am eagerly anticipating receiving the traditional Latin breviary for Christmas [not purchase from Romanitas Press], and I want to give myself a head start so I can learn how to do the red and say the black. $5 seems perfectly fair for a portable rubrics map. hitheringwaters
