# Cognito vs WilliStudy

The clearest difference is rating: Cognito at 4.9 against WilliStudy's 4.5. Cognito also leads on iOS requirement (12.1 vs 17.4). WilliStudy's advantage is review sentiment (80% vs 60%) and device support (5 vs 2). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Cognito holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 10 and 8 respectively. Written reviews complicate that: 60% of Cognito's written reviews are positive against 80% of WilliStudy's, so the app with the better star average is not the one people write more warmly about.

Cognito ships an update every 5 weeks, WilliStudy every 3 weeks. The most recent releases landed on October 7, 2026 and October 3, 2026 respectively.
