# ELEGOO Matrix vs 3D File Viewer

The clearest difference is rating: 3D File Viewer at 5.0 against ELEGOO Matrix's 2.4. ELEGOO Matrix's advantage is in-app purchases (none vs 1) and ratings volume (147 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. 3D File Viewer sells 1 one-off in-app purchase. ELEGOO Matrix asks for nothing beyond the download.

3D File Viewer holds the better App Store score, 5.0 against 2.4. That said, the two scores are not equally well evidenced: ELEGOO Matrix has 147 ratings behind it against 2, so its average is the more settled of the two.

ELEGOO Matrix ships an update fortnightly, 3D File Viewer every 5 weeks. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
