# JavaScript Anywhere JSAnywhere vs HTML Viewer Q

The clearest difference is rating: HTML Viewer Q at 4.4 against JavaScript Anywhere JSAnywhere's 3.5. HTML Viewer Q also leads on ratings volume (2.7K vs 459) and iOS requirement (11.0 vs 15.0). JavaScript Anywhere JSAnywhere's advantage is update cadence (every 2 months vs every 4 months) and review sentiment (55% vs 45%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HTML Viewer Q holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: HTML Viewer Q has 2.7K ratings behind it against 459, so its average is the more settled of the two. Written reviews complicate that: 55% of JavaScript Anywhere JSAnywhere's written reviews are positive against 45% of HTML Viewer Q's, so the app with the better star average is not the one people write more warmly about.

JavaScript Anywhere JSAnywhere ships an update every 2 months, HTML Viewer Q every 4 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
