KIRI Engine is a 3D scanner app for iPhone, Android and the web. It captures objects with photogrammetry from photos or videos, with LiDAR on supported iOS devices, with a featureless scan method for shiny, reflective or transparent surfaces, and with 3D Gaussian Splatting that can be exported as a mesh. Models can come out as production-ready quad meshes with PBR materials, with built-in decimation for reducing polygon counts. A free version is available on any phone, and a paid Pro tier adds more.
The app suits 3D printing hobbyists who want to copy parts and objects, 3D artists collecting assets, game developers who need scanned props with clean topology, and researchers who need a measurement tool without buying a dedicated scanner. Beginners can scan from a phone without a steep learning curve, and users have reported getting a model in around 15 minutes. Professionals benefit from camera controls such as shutter speed and exposure, high-poly output with millions of vertices, and AI auto-rigging that generates a skeleton for scanned characters.
Typical projects include scanning furniture, sculptures or products for e-commerce visuals, and capturing parts for 3D printing. Game artists scan real objects and import quad-mesh models with PBR textures into engines or Blender. Real estate and design users can use a LiDAR-equipped iPhone to scan rooms, create floor plans and produce quick scene visualizations. Artists create ultra-realistic real-time renders with Gaussian Splatting and convert them to meshes for use in other software. Scientists and educators scan specimens or artifacts, and the featureless scan mode handles glossy or clear items that traditional photogrammetry fails on.
