# UCM vs Libros

The clearest difference is rating: UCM at 4.8 against Libros's 3.0. UCM also leads on ratings volume (21 vs 1). Libros's advantage is update cadence (fortnightly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

UCM holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: UCM has 21 ratings behind it against 1, so its average is the more settled of the two.

UCM ships an update monthly, Libros fortnightly. The most recent releases landed on September 24, 2026 and August 25, 2026 respectively.
