The toolbar

The toolbar contains all the commands you need to use Universalis.

Toolbar image

To see the toolbar, tap the middle of the screen.

09 ▾ Displays the calendar and lets you go to any date you want. The calendar page also has a button marked either "More" or "Special", which lets you choose the Office and Mass for the dead, as well as the Commons for the Blessed Virgin Mary, the Martyrs, and so on.

The About Universalis command gives you details about the app, copyrights, acknowledgements and so on.

Use the the Contact Us command to send us email if you need help, have a suggestion, or want to report an error.

The Copy Page command copies the text so that you can paste it into another application.

The Twitter command tweets the Hour you have just been reading.

Hours ▾ Use this command to select the page you want to view.

The Settings screen lets you control various optional settings, such as the prayers and antiphons at Mass and the parallel Latin text in the Liturgy of the Hours. It also lets you set up the daily email service.

Full instructions are here.

Choose the size and style of font you want to see, and also control the brightness of the screen: this includes a "dark mode" if you want to read at night.

Menu buttons in the text

Here and there you will see menu buttons at the right-hand of the text.

These let you choose between available options. For instance:

  • On optional memorials, you can choose whether to celebrate the memorial or stick with the ferial day.
  • On memorials, you can choose whether to use the Mass readings of the memorial or those of the ferial day.
  • In the Liturgy of the Hours, you can choose whether to see the Invitatory Psalm or not, and which Invitatory Psalm to use.
  • In the daytime Hours, you can choose whether to see the psalms of the day, the complementary psalms, or both.
  • In the Order of Mass (and also in Mass Today), you can choose between different penitential rites, Creeds, Eucharistic Prayers, and so on.

When you see a menu button, tap it to see what it does.

Choose your local calendar

Every part of the world has its own local variations from the General Calendar. These include whether some feasts of the Lord such as Epiphany and Ascension are moved to the nearest Sunday, as well as specific local feasts and celebrations. For example, Saint Benedict is celebrated with a memorial in the universal Church but with a feast in Europe, while Saint Willibrord, who isn't in the General Calendar at all, is celebrated with an optional memorial in some English dioceses and a solemnity in the Netherlands.

Universalis tries to guess what your local calendar may be, but its guessing ability is quite limited. To check what calendar you are using:

  1. Tap in the middle of the screen, to display the toolbar.
  2. Display the calendar by pressing the leftmost button in the toolbar.
  3. The calendar has a toolbar of its own at the top of the screen. This shows the name of the local calendar that Universalis is currently using. If this isn't the calendar you want, tap the name and a menu will appear which lets you select the local calendar to be used.


Spoken and sung material is available. Please visit this page for full details and instructions.
