This app converts and displays 3D Gaussian splatting into SBS, anaglyph, or other 3D images. 3D Gaussian splatting is a new scanning method that can reproduce photorealistic 3D scenes, and more and more scanning apps are becoming available on iOS. With this app, you can load a file (.ply .splat) exported from a scanning app, display it in your favorite 3D format, and enjoy 3D images from various perspectives by touch operation. In addition, with USB-C equipped iPhones/iPads, when smart glasses are connected, 3D display on the smart glasses and viewpoint control via touch operation of the connected iPhone/iPad are possible.

Verdict
The clearest difference is rating: UGScan at 4.6 against i3DGS3D's 4.0. UGScan also leads on update cadence (fortnightly vs every 9 months) and ratings volume (16 vs 1). i3DGS3D's advantage is in-app purchases (none vs 5) and review sentiment (100% vs 70%). On price, ads and device support there is nothing between them.

Both are free to download. UGScan sells 5 in-app purchases, starting at $6.99 per month. i3DGS3D asks for nothing beyond the download.
UGScan holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: UGScan has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of UGScan's written reviews are positive against 100% of i3DGS3D's, so the app with the better star average is not the one people write more warmly about.
UGScan ships an update fortnightly, i3DGS3D every 9 months. The most recent releases landed on October 17, 2026 and October 10, 2026 respectively.
