Gaussian SplatKing vs Uchi

SplatKing is a capture app built for Gaussian splatting and radiance field workflows. • It focuses on one outcome: producing high-quality, reconstruction-ready input data you can use in any downstream pipeline. • Key capabilities: simultaneous dual-lens capture (wide + ultra-wide) in photo and video · 4K/30 HEVC with • Standard/Max Fidelity · auto photo cadence · LiDAR mode (1× wide + ARKit depth) with native COLMAP export written on-device • Manual controls (ISO, shutter, white balance, exposure, AF Lock, manual focus, tap-to-focus) across both lenses · minimum shutter speed · optional undistorted exports · session quality summaries. • Structured splatpack.json export.

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.
