# Tis smart control professional vs HTML Viewer

The clearest difference is in-app purchases: Tis smart control professional at none against HTML Viewer's 1. Tis smart control professional also leads on iOS requirement (9.0 vs 17.6). HTML Viewer's advantage is update cadence (every 3 days vs every 5 weeks) and ratings volume (30 vs 2). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. HTML Viewer sells 1 one-off in-app purchase. Tis smart control professional asks for nothing beyond the download.

HTML Viewer holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: HTML Viewer has 30 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Tis smart control professional's written reviews are positive against 93% of HTML Viewer's, so the app with the better star average is not the one people write more warmly about.

Tis smart control professional ships an update every 5 weeks, HTML Viewer every 3 days. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
