Verdict

The call

The clearest difference is rating: HTML Viewer at 4.7 against WebPen's 3.7. HTML Viewer also leads on ads (none vs shown) and review sentiment (93% vs 60%). WebPen's advantage is monetization model (ad-supported vs freemium) and iOS requirement (15.6 vs 17.6). On price, in-app purchases and device support there is nothing between them.
