Verdict
The clearest difference is rating: GCLS Mobile at 4.0 against LibraryThing's 3.5. LibraryThing's advantage is ratings volume (288 vs 4) and iOS requirement (11.0 vs 15.6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
GCLS Mobile holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: LibraryThing has 288 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 47% of LibraryThing's written reviews are positive against 40% of GCLS Mobile's, so the app with the better star average is not the one people write more warmly about.
LibraryThing ships an update every 4 weeks, GCLS Mobile every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
