# Kosmos vs Onleihe 3

The clearest difference is review sentiment: Onleihe 3 at 73% against Kosmos's 16%. Onleihe 3 also leads on update cadence (monthly vs every 6 months) and chart position (#206 vs unranked). Kosmos's advantage is rating (5.0 vs 4.7) and iOS requirement (12.2 vs 15.1). 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.

Kosmos holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Onleihe 3 has 43 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 16% of Kosmos's written reviews are positive against 73% of Onleihe 3's, so the app with the better star average is not the one people write more warmly about.

Kosmos ships an update every 6 months, Onleihe 3 monthly. The most recent releases landed on October 31, 2026 and October 30, 2026 respectively.
