# One Scan vs OpenDocument Reader Pro

The clearest difference is price: One Scan at Free against OpenDocument Reader Pro's $3.99. One Scan also leads on rating (4.7 vs 4.2) and ratings volume (12K vs 292). OpenDocument Reader Pro's advantage is in-app purchases (none vs 10) and chart position (#65 vs unranked). On review sentiment, update cadence, ads and device support there is nothing between them.

One Scan is free to download; OpenDocument Reader Pro costs $3.99 up front. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days. OpenDocument Reader Pro asks for nothing beyond the download.

One Scan holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 292, so its average is the more settled of the two. Written reviews point the same way: 26% of One Scan's written reviews are positive against 20% of OpenDocument Reader Pro's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 1, 2026 and September 29, 2026 respectively.
