The traditional Catholic prayer app
Pray as the Churchhas always prayed.
The Mass, the Divine Office, the Angelus, the Rosary and the novenas of the 1962 rite, each at its hour of your day.
Everything the Traditional Latin Rite asks of a day.
Two thousand years of tradition. The line we hold.
The Roman Rite as it stood before the rupture. The Mass of all ages. The Breviary unchanged. The sacramental rites intact. We built Iter Fidei on this foundation — nothing before it is forgotten, nothing after it is included.
For Catholics who still kneel at the altar rail.
For those who pray the hours in Latin.
For those who go to Confession.
For those who never left.
The Traditional Latin Rite has endured for twenty centuries. It deserves a companion built with the same rigour.
One question, the answer of all time.
Short films that answer from Scripture, the councils and the catechisms. Every line is sourced.
The faith, explained from the sources.
Notes on the liturgy, tradition and the life of prayer — in the light of the sources from before the rupture.

The Catholic app, in a few questions
Is Iter Fidei a Catholic app?
Yes. It is made by traditional Catholics for Catholics who pray the Roman rite as it stood in 1962: the Mass, the Breviary, the Rosary, the novenas and the calendar of that year, in Latin and in English, without advertising. What's inside the app
Does it have the Divine Office — the Breviary of 1962?
Yes: the eight Hours of the Roman Breviary, from Matins to Compline, assembled for each day, Latin and English side by side, with the Little Office of Our Lady. It is the traditional Office, not the Liturgy of the Hours of 1971. The Divine Office app
Is there a rosary app inside?
Yes. The Rosary is prayed decade by decade with its fifteen mysteries — the mysteries of the day already chosen — every prayer in Latin and English, with the Latin recited aloud to pray along. The Rosary app
Can I pray a novena with it?
Yes. The app gives each day of a novena on its day, keeps your place and reminds you daily until the ninth day — the Sacred Heart, St Joseph, St Jude and many more. The novena app
Does it include a Catholic Bible?
Yes: all seventy-three books of the Catholic canon, the Latin Vulgate with the Douay-Rheims beneath, verse by verse, kept on your phone to read without a connection. The Catholic Bible app
Is it free, and when is it available?
