ReceptionRating · Positive reviews · Number of ratings

Cognizer holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Cognizer has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Cognizer's written reviews are positive against 100% of 5x5!? Easy SUDOKU Eccentric Version's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cognizer ships an update every 6 months, 5x5!? Easy SUDOKU Eccentric Version every 3 weeks. Both last shipped on November 2, 2026.
