Santo Rosario

There are evenings when praying the Rosary alone feels like hard work, and what you really want is to be carried along by other voices. Santo Rosario, listed in the App Store as O Terço Mariano, is built for exactly that. It is a Portuguese-language Rosary app in which you pray along with a priest and a choir of the faithful. The effect is closer to joining a parish Rosary than reading prayers off a screen.

What the app does

The app follows the traditional weekly pattern of mysteries: the Joyful on Monday and Saturday, the Sorrowful on Tuesday and Friday, the Glorious on Wednesday and Sunday, and the Luminous on Thursday. It includes the full set of Rosary prayers, so you don't need a booklet beside you. It also invites you into a worldwide network of people praying at the same time, a quiet reminder that the Rosary is never really prayed alone. It is free, and it was updated in early 2026.

Who it suits

The obvious caveat is language. Everything here is in Portuguese, so it is for Portuguese speakers, for families who want to pass the prayer on in Portuguese, or for anyone learning the language who wants to pray in it. If you need English, look elsewhere. The app also has no App Store ratings yet, so there is little feedback from other users to go on.

For Portuguese-speaking Catholics living far from home, an app like this can be a small link to the parish they grew up in, with the same prayers in the same words. Older relatives who pray in Portuguese may find it easier to follow voices than text. It can also be a gentle way to teach children the rhythm of the decades.

The verdict is simple. Santo Rosario is a devout, free and warm way to pray the Rosary in Portuguese with a priest and choir beside you. If Portuguese is your language of prayer, it is well worth a place on your phone.
