The app

Traditio is licensed to you under Apple's standard licence agreement. The app is free: every text, version, calendar and language, with no account.

The texts

The texts, calendars and rules come from the Divinum Officium project, and the app's engine is checked against it page by page. Mistakes can remain: for anything that binds you, the Church's liturgical books prevail.

Who we are
