# PDF Reader Pro Edition® vs uScan

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.

uScan is free to download; PDF Reader Pro Edition® costs $1.99 up front. uScan sells 10 in-app purchases, starting at $3.99 per 7 days. PDF Reader Pro Edition® asks for nothing beyond the download.

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.

PDF Reader Pro Edition® ships an update every 4 months, uScan every 3 weeks. The most recent releases landed on September 24, 2026 and September 26, 2026 respectively.
