Cato is the daily app for living the Catholic faith — learn the catechism, pray the
Rosary, and read Scripture a few minutes a day. Built like Duolingo, taught like the Church.
FIVE-MINUTE LESSONS — bite-size catechesis from the existence of God to the sacraments, the Mass, Scripture, and the last things. Learn by doing, not just reading.
PRAY DAILY — an interactive Rosary, the Ignatian Examen, and guided prayers to open and close your day.
THE BIBLE, BUILT IN — read the NRSV-CE (and La Biblia in Spanish), search any verse, and highlight what speaks to you.
• COMPETE & CONNECT — test your faith in live quiz battles and earn XP for your diocese on the global leaderboard.
• KEEP THE FLAME — daily streaks, coins, and XP to keep the habit.
In English and Spanish. Free to use. No ads, ever.
