Verdict
The clearest difference is review sentiment: 3D Cost at 75% against STL Simple Viewer's 17%. 3D Cost also leads on in-app purchases (none vs 4) and update cadence (every 6 weeks vs every 20 months). STL Simple Viewer's advantage is price (Free vs $0.99) and rating (4.3 vs 1.0). On ads, device support and iOS requirement there is nothing between them.

STL Simple Viewer is free to download; 3D Cost costs $0.99 up front. STL Simple Viewer sells 4 in-app purchases, starting at $0.99 per 7 days. 3D Cost asks for nothing beyond the download.
STL Simple Viewer holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: STL Simple Viewer has 866 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 17% of STL Simple Viewer's written reviews are positive against 75% of 3D Cost's, so the app with the better star average is not the one people write more warmly about.
STL Simple Viewer ships an update every 20 months, 3D Cost every 6 weeks. The most recent releases landed on September 26, 2026 and September 21, 2026 respectively.
