# QuizDB vs ScreenZen

The clearest difference is ratings volume: ScreenZen at 54K against QuizDB's 137. ScreenZen also leads on review sentiment (93% vs 80%) and chart position (#139 vs unranked). QuizDB's advantage is update cadence (every 9 days vs every 3 weeks) and iOS requirement (11.0 vs 16.4). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. QuizDB sells 1 one-off in-app purchase and ScreenZen sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for QuizDB against 4.9 for ScreenZen. That said, the two scores are not equally well evidenced: ScreenZen has 54K ratings behind it against 137, so its average is the more settled of the two. Written reviews are what separate them: 80% of QuizDB's written reviews are positive against 93% of ScreenZen's.

QuizDB ships an update every 9 days, ScreenZen every 3 weeks. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
