Verdict

The call

The clearest difference is in-app purchases: JettWatch at none against HTML Viewer's 1. JettWatch also leads on iOS requirement (13.0 vs 17.6). HTML Viewer's advantage is update cadence (every 3 days vs every 3 weeks). On price, ads and device support there is nothing between them.
