Reimagine Fx iOS App
Viewport
Open, inspect & preview 3D files on iPhone.
Viewport is a fast, focused 3D viewer built by Amar Shinde at Reimagine Fx. Open models straight from the Files app — iCloud Drive, Google Drive, Dropbox, OneDrive, Downloads or AirDrop — and inspect them in a clean, professional viewport. Orbit, study materials and scale, play animations, and preview in AR. No account. No cloud. No clutter.
Now live on the App Store. Everything runs on-device — your files never leave your iPhone.
Features
A pocket viewport for 3D artists
Inspect like a pro
Smooth orbit, pan, pinch-zoom and double-tap to frame. Studio lighting presets with adjustable intensity.
Render channels
Switch between shaded, albedo, normals, roughness and UV views — plus a wireframe overlay that preserves quad and triangle topology — to inspect exactly how a model is built.
Animation playback
Plays node/transform animation and skeletal (bone) skinning on supported models, with simple play / pause / loop.
Scene info
Bounding box, dimensions, vertex, triangle, material and texture counts — real values, never faked. Share stats or the model file.
AR & capture
AR Quick Look for USDZ and Reality files, turntable auto-spin, a reference ground grid, plus screenshot & share.
Supported Formats
Bring your models as they are
Pick a model together with its texture and material files to keep its look intact. Viewport loads each format on the path that renders it best.

Getting Started
How it works
Install Viewport
Get Viewport from the App Store on your iPhone or iPad.
Open a 3D file
Tap “Open 3D File”, or send a model to Viewport from any app via the share sheet.
Bring textures along
For OBJ/FBX/glTF, select the model and its texture files together so materials resolve.
Orbit & inspect
Orbit, pan, zoom and frame. Tweak lighting, background and render channels.
Play animation
Animated models auto-play with a play / pause / loop transport.
Preview in AR
Drop USDZ and Reality models into your space with AR Quick Look.
FAQ
Questions & answers
Which formats does Viewport support?
USD-family (USDZ, USD, USDA, USDC) and .reality load natively. OBJ, STL and PLY convert on-device. FBX, glTF, GLB, DAE, BLEND and 20+ more load through the built-in importer.
Does it play animations?
Yes. Viewport plays node/transform animation across formats, and skeletal (bone) skinning on supported models and iOS versions. A transport bar appears automatically when a model is animated.
Does my model leave my device?
No. All loading, conversion and rendering happen entirely on your iPhone. Viewport has no accounts, no cloud and never uploads your files.
Why does my model look untextured?
Models without baked materials render as neutral “clay”. For OBJ/FBX/glTF, import the model together with its texture files so Viewport can resolve them.
Can I view models in AR?
USDZ and Reality files open in Apple’s AR Quick Look so you can place them in the real world at true scale.
How much does it cost?
Viewport is a focused utility with no subscriptions or ads. Pricing is shown on its App Store page.
