# Quick STL Viewer vs 3D File Viewer

The clearest difference is update cadence: Quick STL Viewer at every 6 days against 3D File Viewer's every 5 weeks. Quick STL Viewer also leads on ratings volume (12 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Quick STL Viewer sells 3 in-app purchases, starting at $2.99 per 7 days and 3D File Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Quick STL Viewer against 5.0 for 3D File Viewer. That said, the two scores are not equally well evidenced: Quick STL Viewer has 12 ratings behind it against 2, so its average is the more settled of the two.

Quick STL Viewer ships an update every 6 days, 3D File Viewer every 5 weeks. The most recent releases landed on October 31, 2026 and October 29, 2026 respectively.
