# One Scan vs PDF Scanner

The clearest difference is rating: One Scan at 4.7 against PDF Scanner's 4.1. One Scan also leads on review sentiment (26% vs 0%) and ratings volume (12K vs 12). PDF Scanner's advantage is iOS requirement (16.5 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and PDF Scanner sells 3 in-app purchases, starting at $4.99 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 4.1. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 12, 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 0% of PDF Scanner's.
