Verdict
The clearest difference is review sentiment: HTML Viewer at 93% against OpenHTML's 67%. HTML Viewer also leads on ratings volume (26 vs 4). OpenHTML's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. HTML Viewer sells 1 one-off in-app purchase and OpenHTML sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
OpenHTML holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: HTML Viewer has 26 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of HTML Viewer's written reviews are positive against 67% of OpenHTML's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 13, 2026 and October 1, 2026 respectively.
