# PDF Scanner App vs One Scan

The clearest difference is ads: One Scan at none against PDF Scanner App's shown. One Scan also leads on rating (4.7 vs 4.5). PDF Scanner App's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (13.0 vs 26.0). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. PDF Scanner App sells 10 in-app purchases, starting at $4.99 per month and One Scan sells 10 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

One Scan holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 6.3K and 12K respectively. Written reviews complicate that: 28% of PDF Scanner App'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 Scanner App ships an update every 3 weeks, One Scan every 2 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
