Verdict
The clearest difference is in-app purchases: PDF Reader at none against QR Code Master's 5. PDF Reader also leads on rating (4.8 vs 4.4) and iOS requirement (13.0 vs 17.0). QR Code Master's advantage is ads (none vs shown) and chart position (#80 vs unranked). On price, ratings volume, update cadence and device support 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. PDF Reader asks for nothing beyond the download.
PDF Reader holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 3.2K and 1.7K respectively. Written reviews complicate that: 61% of PDF Reader's written reviews are positive against 72% of QR Code Master's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
