# ICSI vs QR Code Master

The clearest difference is rating: ICSI at 5.0 against QR Code Master's 4.4. ICSI also leads on in-app purchases (none vs 5) and device support (3 vs 1). QR Code Master's advantage is update cadence (weekly vs every 6 weeks) and ratings volume (1.8K vs 1). On price and ads there is nothing between them.

Both are free to download. QR Code Master sells 5 in-app purchases, starting at $9.99 per 7 days. ICSI asks for nothing beyond the download.

ICSI holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: QR Code Master has 1.8K ratings behind it against 1, so its average is the more settled of the two.

ICSI ships an update every 6 weeks, QR Code Master weekly. The most recent releases landed on September 26, 2026 and October 16, 2026 respectively.
