# HTML Viewer Pro vs WebPen

The clearest difference is monetization model: WebPen at ad-supported against HTML Viewer Pro's free with in-app purchases. WebPen also leads on review sentiment (60% vs 49%). HTML Viewer Pro's advantage is ratings volume (45 vs 7) and iOS requirement (12.0 vs 15.6). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. HTML Viewer Pro sells 2 in-app purchases, starting at $1.99 per month and WebPen sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HTML Viewer Pro holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: HTML Viewer Pro has 45 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 49% of HTML Viewer Pro's written reviews are positive against 60% of WebPen's, so the app with the better star average is not the one people write more warmly about.

HTML Viewer Pro ships an update every 15 months, WebPen every 8 months. The most recent releases landed on October 10, 2026 and October 3, 2026 respectively.
