Verdict
The clearest difference is rating: STL Simple Viewer at 4.3 against Stamp STL Maker's 3.0. STL Simple Viewer also leads on ratings volume (909 vs 1). Stamp STL Maker's advantage is review sentiment (50% vs 18%) and update cadence (every 2 months vs every 5 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Stamp STL Maker sells 5 in-app purchases, starting at $2.99 per month 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 3.0. That said, the two scores are not equally well evidenced: STL Simple Viewer has 909 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Stamp STL Maker'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.
Stamp STL Maker ships an update every 2 months, STL Simple Viewer every 5 months. The most recent releases landed on September 25, 2026 and October 19, 2026 respectively.
