# HTML Viewer Pro vs HTML Keep

The clearest difference is review sentiment: HTML Keep at 100% against HTML Viewer Pro's 49%. HTML Keep also leads on rating (5.0 vs 3.9) and ads (none vs shown). HTML Viewer Pro's advantage is ratings volume (45 vs 1) and iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support 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 HTML Keep sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

HTML Keep holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: HTML Viewer Pro has 45 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 49% of HTML Viewer Pro's written reviews are positive against 100% of HTML Keep's.

HTML Viewer Pro ships an update every 15 months, HTML Keep every 2 days. The most recent releases landed on October 10, 2026 and October 2, 2026 respectively.
