# Grades vs QR Code Reader

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.

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.

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.
