# Cambridge Reader vs ClassWiz Calc App QR

The clearest difference is in-app purchases: Cambridge Reader at none against ClassWiz Calc App QR's 1. Cambridge Reader also leads on ads (none vs shown) and rating (2.6 vs 2.1). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. ClassWiz Calc App QR sells 1 in-app purchase, starting at $14.99 per year. Cambridge Reader asks for nothing beyond the download.

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.

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