Verdict

The call

PDF Scanner and One Scan both sit at 4.6 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 update cadence (every 2 weeks vs monthly) and iOS requirement (15 vs 18.0). One Scan's advantage is ads (none vs shown) and ratings volume (12K vs 787). On price, rating, in-app purchases and monetization model there is nothing between them.
