Verdict

The call

The clearest difference is rating: PDF Expert at 4.7 against QR's 3.0. PDF Expert also leads on ratings volume (217K vs 2) and chart position (#74 vs unranked). QR's advantage is monetization model (free vs freemium) and iOS requirement (12.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. PDF Expert sells 9 in-app purchases, starting at $9.99 per month and QR sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

PDF Expert holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: PDF Expert has 217K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 45% of PDF Expert's written reviews are positive against 33% of QR's.

UpkeepUpdate frequency

PDF Expert ships an update fortnightly, QR every 3 weeks. The most recent releases landed on November 14, 2026 and November 6, 2026 respectively.
