Verdict

The call

The clearest difference is price: uScan at Free against PDF Reader Pro Edition®'s $1.99. uScan also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (15K vs 1.7K). PDF Reader Pro Edition®'s advantage is in-app purchases (none vs 11) and ads (none vs shown). On rating, review sentiment, chart position and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

uScan holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: uScan has 15K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews complicate that: 54% of PDF Reader Pro Edition®'s written reviews are positive against 47% of uScan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Reader Pro Edition® ships an update every 4 months, uScan every 3 weeks. Both last shipped on September 24, 2026.
