PDF Scanner－Document Scanner also leads on rating (5.0 vs 4.7) and iOS requirement (15.6 vs 26.0). One Scan's advantage is ratings volume (12K vs 10).

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and PDF Scanner－Document Scanner sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
