# Biblioteket vs Polylino

The clearest difference is rating: Biblioteket at 5.0 against Polylino's 4.2. Biblioteket also leads on iOS requirement (13.0 vs 15.6). Polylino's advantage is review sentiment (33% vs 0%) and update cadence (every 3 weeks vs every 3 months). 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.

Biblioteket holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Polylino has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Biblioteket's written reviews are positive against 33% of Polylino's, so the app with the better star average is not the one people write more warmly about.

Biblioteket ships an update every 3 months, Polylino every 3 weeks. The most recent releases landed on September 19, 2026 and September 20, 2026 respectively.
