Verdict

The call

The clearest difference is in-app purchases: HTML Viewer+ at none against OpenHTML's 1. HTML Viewer+ also leads on review sentiment (100% vs 67%) and iOS requirement (15.6 vs 18.0). OpenHTML's advantage is update cadence (every 5 days vs every 2 months). On price, ads and device support there is nothing between them.
