# Library Catalog vs Apollo Books Tracker

The clearest difference is rating: Library Catalog at 4.8 against Apollo Books Tracker's 3.0. Library Catalog also leads on ratings volume (15 vs 2). Apollo Books Tracker's advantage is review sentiment (100% vs 73%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Library Catalog holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Library Catalog has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 73% of Library Catalog's written reviews are positive against 100% of Apollo Books Tracker's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 24, 2026 and October 14, 2026 respectively.
