Verdict
The clearest difference is in-app purchases: Jo's PDF Text Viewer at none against JustPDF's 1. Jo's PDF Text Viewer also leads on iOS requirement (15.0 vs 18.6). JustPDF's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, ads and device support there is nothing between them.
