# Quollect vs Cat's Library

The clearest difference is rating: Cat's Library at 4.8 against Quollect's 3.0. Cat's Library also leads on update cadence (every 4 days vs every 2 weeks) and ratings volume (37 vs 2). Quollect's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quollect sells 3 in-app purchases, starting at $3.99 per month and Cat's Library sells 7 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Cat's Library holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Cat's Library has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 88% of Quollect's written reviews are positive against 87% of Cat's Library's, so the app with the better star average is not the one people write more warmly about.

Quollect ships an update every 2 weeks, Cat's Library every 4 days. The most recent releases landed on September 23, 2026 and September 26, 2026 respectively.
