Verdict
The clearest difference is in-app purchases: Complex Calc at none against PDF Watch Viewer's 9. Complex Calc also leads on rating (5.0 vs 4.6) and iOS requirement (12.0 vs 17.0). PDF Watch Viewer's advantage is update cadence (every 11 days vs every 6 months) and ratings volume (373 vs 2). On price, ads and device support there is nothing between them.
