# Polylino vs Biblio

The clearest difference is rating: Biblio at 4.7 against Polylino's 4.2. Biblio also leads on ratings volume (89 vs 5). Polylino's advantage is review sentiment (33% vs 0%). 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.

Biblio holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Biblio has 89 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 33% of Polylino's written reviews are positive against 0% of Biblio's, so the app with the better star average is not the one people write more warmly about.

Polylino ships an update every 3 weeks, Biblio monthly. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
