Viewport 3D
Open & preview 3D Models
Free
Open and inspect large 3D models on iPhone and iPad, with improved AR placement, realistic shadows, and Real World or Studio AR lighting.
Viewport is a fast, focused 3D viewer built for artists. Open models straight from the Files app on iPhone or iPad — iCloud Drive, Google Drive, Dropbox, OneDrive, Downloads or AirDrop — and inspect them in a clean, professional viewport. No account. No cloud. No clutter.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
AR, large-file, iPad, and rendering improvements:
• Fixed textures appearing distorted or stretched on some glTF/GLB models.
• Sharper surface detail — normal maps now stay locked to the model as you orbit.
• Improved stability and memory use for very large GLB files.
• Rebuilt AR placement with a clearer target, steadier surface placement, realistic shadows, and improved model sizing.
• Added Real World and Studio lighting options in AR.
• Added full iPad support with adaptive layouts and multitasking.
• Fixed the final Recent Files row being cut off.
• Clearer message when a file has no displayable surfaces.
• Improved initial model framing so objects open fully visible.
• Improved stability when switching or closing models while background preparation is running.
Thanks for using Viewport!
