The clearest difference is in-app purchases: Sentryx™ AMR at none against HTML Viewer Pro's 2. Sentryx™ AMR also leads on ads (none vs shown) and update cadence (fortnightly vs every 15 months). HTML Viewer Pro's advantage is iOS requirement (12.0 vs 16.4). On price and device support there is nothing between them.
