# QR Pro vs PDF Scanner

The clearest difference is review sentiment: QR Pro at 73% against PDF Scanner's 10%. QR Pro also leads on ads (none vs shown) and update cadence (weekly vs every 52 months). PDF Scanner's advantage is rating (5.0 vs 4.5). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PDF Scanner holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: QR Pro has 29K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 73% of QR Pro's written reviews are positive against 10% of PDF Scanner's, so the app with the better star average is not the one people write more warmly about.

QR Pro ships an update weekly, PDF Scanner every 52 months. The most recent releases landed on October 28, 2026 and October 21, 2026 respectively.
