Uchi : 3D Scan & Share

Uchi is a 3D scanning app for iPhone. Capture the spaces around you, generate realistic 3D models, and share them with the world.

HOW IT WORKS
• Start a scan, stand in place, and turn around — a guided viewfinder helps you capture 8 directions
• Uchi generates a photorealistic 3D space (3D Gaussian Splatting) in the cloud
• On LiDAR devices, you can also capture 3D meshes and 3D room layouts (RoomPlan)
• Publish your scan to the map, or keep it just for yourself

AN OPEN 3D MAP, BUILT TOGETHER
Published 3D data becomes open data (CC BY-SA 4.0) — free for anyone to view, download, and build upon. Indoors or outdoors, let's build an open 3D record of the world's public spaces together: stations, shops, campuses, parks and more. Prefer privacy? Set a scan to "Only me" and it stays yours.

FEATURES
• Guided 3D capture — no special hardware required
• Photorealistic 3D (Gaussian Splatting), mesh, and room-layout capture modes
• Explore scans from around the world on a 3D map, with leaderboards
• Download shared models in standard formats
• Sign in with Apple or Google

CAPTURE RESPONSIBLY
• Capture public spaces only — no private residences
• Avoid capturing people and personal information
• Report and block tools are built in; removal requests are always honored

Requirements: iPhone with iOS 18 or later. Mesh/RoomPlan capture requires a LiDAR-equipped or 6GB+ RAM device.
