Verdict

The call

PDF Reader and PDF Converter both sit at 4.5 stars, but that hides the real split: 81% of PDF Reader's written reviews are positive against 50% of PDF Converter's. PDF Reader also leads on ratings volume (3.5K vs 92) and iOS requirement (13.0 vs 15.6). PDF Converter's advantage is update cadence (every 3 weeks vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.
