Verdict

The call

The clearest difference is in-app purchases: QR Code Reader at none against Grades's 7. QR Code Reader also leads on review sentiment (84% vs 70%) and ratings volume (160K vs 13K). Grades's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.

Both are free to download. Grades sells 7 in-app purchases, starting at $3.99 per month. QR Code Reader asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Grades holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: QR Code Reader has 160K ratings behind it against 13K, so its average is the more settled of the two. Written reviews complicate that: 70% of Grades's written reviews are positive against 84% of QR Code Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Grades ships an update every 2 weeks, QR Code Reader every 2 months. The most recent releases landed on October 1, 2026 and October 2, 2026 respectively.
