ModelPlay supports 3D model classification and viewing, 3D model import and export, and users can personalize each 3D model and save the settings. When using ModelPlay, users don't need to have professional 3D knowledge, just through simple operation, you can get very stunning 3D effects. -3D Model Import and Export Supports import and export of many common 3D format files such as GLB, FBX, OBJ, STL, PLY, 3MF, and so on. -3D Model Categorization Categorize 3D models through folders, support both list and grid display, sorting and editing, and setting image size. -3D Model Lighting Settings Support to set the lighting of the scene where the 3D model is located: support preset lighting combination settings, light color, light intensity, light shadow settings, ambient light color settings, and halo intensity settings. You can create colorful lighting effects through multiple combination settings. 3D Model Background Settings Supports setting the background of the scene where the 3D model is located: supports solid color background and sky box background. You can set “whether to show the ground” to get different scene atmosphere effects. 3D Model Material Settings Support to set the material of 3D model: support default texture material, line material, metal material, transparent material and other material switching. Support to view the original material and texture. -3D Model Animation Settings Support 3D model skeleton display, support animation play and pause, support auto rotate, support dynamic skeleton, support multiple animation clips switch play. -3D Model Position Setting Support 3D model position offset and rotation setting. Support camera view angle setting, you can set different optimal display view angles for different 3D models. -3D Model Mesh Settings Count the number of sub-mesh and mesh vertices of the 3D model, support whether the sub-mesh is visible or not setting, support component separation, and support putting the sub-mesh as the center. -3D Model Cover Settings The 3D model cover will be automatically generated when the 3D model is opened for the first time, support to modify the cover. Note: Updates and Feedback ModelPlay will make continuous updates to provide more 3D setting effects in the subsequent releases. Feel free to provide suggestions to ModelPlay via comments!
3D Kit

Open, explore, and inspect 3D models on your iPhone or iPad. 3D Kit is a fast, intuitive viewer built for makers, designers, engineers, and anyone who works with 3D files. Drop in an STL, OBJ, USDZ, or 3MF file and see it rendered instantly. Orbit around your model with smooth turntable controls, zoom in to inspect fine details, and get a complete breakdown — triangle count, vertex count, dimensions, bounding box, file size, volume, and surface area. BUILT FOR 3D PRINTING Choose from popular printer bed presets or enter custom dimensions to see exactly how your model fits on the build plate. A floor grid gives you spatial reference, and real-time measurement overlays show width, height, and depth in millimeters — so you can verify scale before you slice. Whether you are checking a downloaded file or reviewing your own design exports, 3D Kit gives you a quick, reliable way to preview models without launching a full slicer or CAD application. SEE YOUR MODEL IN THE REAL WORLD Place any 3D model into your physical environment using augmented reality. Point your camera at a flat surface, tap to place, and walk around your model as if it were sitting right in front of you. AR mode is perfect for checking the real-world size of a print, showing a design to someone who does not use CAD software, or seeing how a model looks on your desk before committing to a print. Measurements work in AR too, so you can verify dimensions while viewing the model in context. MAKE IT YOURS Customize every aspect of the viewing experience. Change the object color, floor color, sky color, grid color, grid line width, and ruler line color. Choose from camera presets — front, back, left, right, top, bottom, and isometric — or orbit freely to find the perfect angle. All appearance settings persist across sessions. CAPTURE AND SHARE Take high-resolution screenshots or record smooth video walkthroughs. Export to your photo library, save to Files, or share directly to any app. Video recording works in both the standard viewport and AR mode. YOUR MODEL LIBRARY Import files from the Files app, AirDrop, email attachments, or any app that shares 3D files. 3D Kit organizes your models in a built-in library with quick access to recent files. Rename, delete, and manage your collection without leaving the app. Browse the included sample models to explore what 3D Kit can do, no files required.

Verdict
The clearest difference is update cadence: 3D Kit at every 5 days against ModelPlay's every 2 weeks. ModelPlay's advantage is device support (4 vs 2) and iOS requirement (12.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
