Verdict
The clearest difference is rating: STL Simple Viewer at 4.3 against Stitch Viewer Pro's 2.0. STL Simple Viewer also leads on ratings volume (917 vs 5) and update cadence (every 5 months vs every 28 months). Stitch Viewer Pro's advantage is ads (none vs shown) and iOS requirement (9.0 vs 17.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stitch Viewer Pro sells 1 one-off in-app purchase and STL Simple Viewer sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
STL Simple Viewer holds the better App Store score, 4.3 against 2.0. That said, the two scores are not equally well evidenced: STL Simple Viewer has 917 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 23% of Stitch Viewer Pro's written reviews are positive against 18% of STL Simple Viewer's, so the app with the better star average is not the one people write more warmly about.
Stitch Viewer Pro ships an update every 28 months, STL Simple Viewer every 5 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
