Sketch 3D Model for Viewer is a mobile viewer for opening, rotating, zooming, and inspecting 3D models on iPhone or iPad. GLB files can be opened directly from the device and kept in a local project library. Users can import additional 3D and CAD formats, including glTF, OBJ, FBX, STL, DAE, 3MF, PLY, USD, and STEP, which are converted to GLB by a private conversion server before being saved locally. The developer says source files and generated results are automatically deleted from that server after seven days. Free access supports files up to one megabyte. Premium supports imports up to 100 megabytes and removes advertising while active. The listing includes a subscription restore option but does not state the subscription price or billing period. The app is intended for personal model review and lightweight visualization; users should import only files they own or are authorized to use.
