Verdict

The call

HTML Viewer Pro and XML Viewer Converter JSON PDF both sit at 3.9 stars, but that hides the real split: 47% of HTML Viewer Pro's written reviews are positive against 4% of XML Viewer Converter JSON PDF's. HTML Viewer Pro also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (12.0 vs 14.0.0). XML Viewer Converter JSON PDF's advantage is ads (none vs shown) and update cadence (fortnightly vs every 15 months). On price, rating, ratings volume and in-app purchases there is nothing between them.
