# QR Barcode Scanner vs Decision Logic

The clearest difference is rating: QR Barcode Scanner at 4.7 against Decision Logic's 4.1. QR Barcode Scanner also leads on ads (none vs shown). Decision Logic's advantage is review sentiment (80% vs 67%) and iOS requirement (14.0.0 vs 17.0). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. QR Barcode Scanner sells 3 in-app purchases, starting at $0.99 per month and Decision Logic sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

QR Barcode Scanner holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 31 and 12 respectively. Written reviews complicate that: 67% of QR Barcode Scanner's written reviews are positive against 80% of Decision Logic's, so the app with the better star average is not the one people write more warmly about.

QR Barcode Scanner ships an update every 6 weeks, Decision Logic every 3 weeks. The most recent releases landed on October 24, 2026 and October 10, 2026 respectively.
