# PDF Scanner vs One Scan

PDF Scanner and One Scan both sit at 4.7 stars, but that hides the real split: 77% of PDF Scanner's written reviews are positive against 26% of One Scan's. PDF Scanner also leads on iOS requirement (15 vs 18.0). One Scan's advantage is ads (none vs shown) and ratings volume (12K vs 788). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. PDF Scanner sells 10 in-app purchases, starting at $2.99 per 7 days 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.

On the App Store both sit at effectively the same score — 4.7 for PDF Scanner against 4.7 for One Scan. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 788, so its average is the more settled of the two. Written reviews are what separate them: 77% of PDF Scanner's written reviews are positive against 26% of One Scan's.

PDF Scanner ships an update every 2 weeks, One Scan fortnightly. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
