# HTML Viewer vs ProScan

The clearest difference is review sentiment: ProScan at 100% against HTML Viewer's 25%. ProScan also leads on in-app purchases (none vs 4) and rating (5.0 vs 4.6). HTML Viewer's advantage is ads (none vs shown) and update cadence (every 8 days vs every 3 weeks). On price and device support there is nothing between them.

Both are free to download. HTML Viewer sells 4 in-app purchases, starting at $14.99 per year. ProScan asks for nothing beyond the download.

ProScan holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: HTML Viewer has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 25% of HTML Viewer's written reviews are positive against 100% of ProScan's.

HTML Viewer ships an update every 8 days, ProScan every 3 weeks. The most recent releases landed on September 16, 2026 and September 12, 2026 respectively.
