ReceptionRating · Positive reviews · Number of ratings

Cambridge Reader holds the better App Store score, 2.6 against 2.1. That said, the two scores are not equally well evidenced: Cambridge Reader has 53 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 10% of Cambridge Reader's written reviews are positive against 13% of ClassWiz Calc App QR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cambridge Reader ships an update every 6 months, ClassWiz Calc App QR every 3 months. Both last shipped on October 24, 2026.
