# QuickSource vs HTML Viewer Pro

The clearest difference is rating: HTML Viewer Pro at 3.9 against QuickSource's 3.3. HTML Viewer Pro also leads on ratings volume (45 vs 3). QuickSource's advantage is ads (none vs shown) and update cadence (monthly vs every 15 months). On price, in-app purchases, monetization model and device support there is nothing between them.

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

HTML Viewer Pro holds the better App Store score, 3.9 against 3.3. That said, the two scores are not equally well evidenced: HTML Viewer Pro has 45 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of QuickSource's written reviews are positive against 47% of HTML Viewer Pro's, so the app with the better star average is not the one people write more warmly about.

QuickSource ships an update monthly, HTML Viewer Pro every 15 months. The most recent releases landed on August 14, 2026 and September 5, 2026 respectively.
