The Khronos glTF Viewer is an easy-to-use application that lets you view and interact with 3D models in the Khronos glTF 2.0 file format, and includes support for viewing in augmented reality. glTF is the open, industry-standard 3D asset format for the efficient transmission and loading of 3D scenes and models by engines and applications. It is an ISO/IEC International Standard that has become the 3D asset delivery format of choice across the web and real-time applications. Key App Features: • Built-In Sample Models – View sample glTF models showcasing features like physically-based rendering and animation • Object Mode – Rotate, zoom, or pan a 3D model to view it from various angles • AR Mode – Place a 3D model on real-world surfaces with augmented reality • File Browser – Browse and display your own glTF files, including optional integration with iCloud Drive All the features found in the core glTF 2.0 specification are supported, plus a number of glTF extensions, including Physically Based Rendering (PBR) effects such as clearcoat.

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 review sentiment: i3DGS3D at 100% against Khronos glTF Viewer's 50%. i3DGS3D also leads on iOS requirement (14.0 vs 16.0). Khronos glTF Viewer's advantage is rating (4.3 vs 4.0) and ratings volume (4 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Khronos glTF Viewer holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 50% of Khronos glTF Viewer'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.
