# Catholic Encyclopedia vs CatholicBrain

The clearest difference is rating: Catholic Encyclopedia at 4.5 against CatholicBrain's 3.3. Catholic Encyclopedia also leads on review sentiment (64% vs 33%) and ratings volume (52 vs 7). CatholicBrain's advantage is in-app purchases (none vs 1) and update cadence (every 5 weeks vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. Catholic Encyclopedia sells 1 in-app purchase, starting at $0.49 per 7 days. CatholicBrain asks for nothing beyond the download.

Catholic Encyclopedia holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Catholic Encyclopedia has 52 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 64% of Catholic Encyclopedia's written reviews are positive against 33% of CatholicBrain's.

Catholic Encyclopedia ships an update every 3 months, CatholicBrain every 5 weeks. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
