# Classkick vs Sadlier Reader

The clearest difference is rating: Sadlier Reader at 3.7 against Classkick's 3.1. Sadlier Reader also leads on device support (3 vs 1) and iOS requirement (13.4 vs 15). Classkick's advantage is review sentiment (33% vs 0%) and update cadence (every 9 days vs every 25 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.

Sadlier Reader holds the better App Store score, 3.7 against 3.1. That said, the two scores are not equally well evidenced: Classkick has 728 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of Classkick's written reviews are positive against 0% of Sadlier Reader's, so the app with the better star average is not the one people write more warmly about.

Classkick ships an update every 9 days, Sadlier Reader every 25 months. Both last shipped on October 24, 2026.
