Verdict
The clearest difference is price: One Scan at Free against PDF Reader Pro Edition®'s $1.99. One Scan also leads on rating (4.7 vs 4.4) and ratings volume (12K vs 1.7K). PDF Reader Pro Edition®'s advantage is in-app purchases (none vs 10) and review sentiment (54% vs 26%). On update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
One Scan is free to download; PDF Reader Pro Edition® costs $1.99 up front. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days. PDF Reader Pro Edition® asks for nothing beyond the download.
One Scan holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Scan has 12K 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 26% of One Scan'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, One Scan every 2 months. Both last shipped on September 24, 2026.
