# FishCure vs QuizKnock

The clearest difference is in-app purchases: QuizKnock at none against FishCure's 10. QuizKnock also leads on rating (4.9 vs 4.4) and review sentiment (82% vs 54%). FishCure's advantage is update cadence (weekly vs every 6 weeks) and ratings volume (4.3K vs 72). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. FishCure sells 9 one-off in-app purchases. QuizKnock asks for nothing beyond the download.

QuizKnock holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: FishCure has 4.3K ratings behind it against 72, so its average is the more settled of the two. Written reviews point the same way: 54% of FishCure's written reviews are positive against 82% of QuizKnock's.

FishCure ships an update weekly, QuizKnock every 6 weeks. Both last shipped on October 26, 2026.
