# STL Simple Viewer vs 3D Model Importer PBR Edition

The clearest difference is review sentiment: 3D Model Importer PBR Edition at 100% against STL Simple Viewer's 18%. 3D Model Importer PBR Edition also leads on iOS requirement (11.0 vs 17.0). STL Simple Viewer's advantage is rating (4.3 vs 1.6) and ratings volume (920 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. STL Simple Viewer sells 4 in-app purchases, starting at $0.99 per 7 days and 3D Model Importer PBR Edition sells 1 in-app purchase, starting at $6.49 per month. Whichever you choose, the download price is not the number that matters.

STL Simple Viewer holds the better App Store score, 4.3 against 1.6. That said, the two scores are not equally well evidenced: STL Simple Viewer has 920 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 18% of STL Simple Viewer's written reviews are positive against 100% of 3D Model Importer PBR Edition's, so the app with the better star average is not the one people write more warmly about.
