Verdict

The call

The clearest difference is rating: HTML Viewer Pro at 3.9 against Http Ninja's 2.8. HTML Viewer Pro also leads on review sentiment (49% vs 25%) and ratings volume (45 vs 5). Http Ninja's advantage is ads (none vs shown) and update cadence (every 2 months vs every 15 months). On price, in-app purchases, monetization model and device support there is nothing between them.
