3D scanning has never been simpler with KIRI Engine: create high-quality 3D models on your phone within minutes. Dive into 3D scanning and modeling tailored for artists, designers, engineers, and 3D printing enthusiasts. Unleash the Power of 3D Scanning: • Photogrammetry: 3D scan with Photo Scan to transform your photos into high-quality 3D models. • NSR (Neural Surface Reconstruction): 3D Scan featureless/shiny objects with a video processed by Neural Radiance Fields (NeRF) integrated Featureless Object Scan. • 3D Gaussian Splatting: Obtain full 3D visualizations with a video, scan and capture all elements in your scene, including reflections. Create Your Own 3D Model through a Delightful Experience: • Capturing: Snapping photos replaces your 3D modeling process, obtain a detailed 3D mesh in just minutes from scanning to generating. • Functional Free Version: Dive into the world of photogrammetry without paying a cent for subscriptions, a LiDAR sensor, or an expensive 3D Scanner. Upload unlimited 3D scans and export at least 3 times per week. Edit, Refine, and Personalize Your Creations: • Edit: Refine 3D models with editing tools; adjust your files in Photo Scan, Featureless Object Scan, and 3D gaussian splats. • Precision: Choose specific photos for processing to ensure detailed, high-quality 3D models. • Cleanup: Auto Object Masking for noise-free, clean models during capture by eliminating background elements. This feature also allows the object to be moved during the capture. • Preview: Employ the 3D viewer and augmented reality panels to directly visualize and adjust your completed 3D model. Share, Export, and Make Use of Your 3D Models: • For Free: free registration and unlimited scanning, with at least 3 exports weekly. • Share: On various platforms such as Sketchfab, Thingiverse, GeoScan, and more. • Formats: Export in OBJ, STL, FBX, GLTF, GLB, USDZ, PLY, XYZ, compatible with Blender 3D, Unreal Engine, Autodesk Maya, etc. • Wide usage: For game development, VFX, VR/AR 3D content creation, 3D printing, 3D visualization, and many more. • Precision Without LiDAR: KIRI’s advanced algorithms provide scanning quality that is on par with LiDAR sensors. KIRI Engine Pro – For Those Who Demand More: • Upload: Pro users can leverage camera rolls, ensuring a flexible 3D scanning experience. • Quad-Mesh Retopology: Refine scanned 3D models with automatic quad-mesh adjustment. • AI PBR Material Generation: Attain lifelike textures with AI-generated PBR materials. • Advanced Camera System: Perfect each shot with fine-tuned camera settings for impeccable 3D scans. • Featureless Object Scan: Utilizes Neural Surface Reconstruction (NSR) for scanning shiny/reflective surfaces, a first in practical 3D scanning with KIRI Engine. • 3D Gaussian Splatting: Experience the future of 3D scanning and capture accurate 3D scenes with a short video; edit using tools like sphere/plane cutters and brushes. Export in native format or OBJ. • WEB Version Access: KIRI Engine WEB offers professional-grade model creation from DSLR photo sets or drone scans, enhancing accuracy in mappings and drone-based 3D surveys.

Verdict
The clearest difference is rating: KIRI Engine at 4.4 against Pixel 3D's 3.9. KIRI Engine also leads on ratings volume (1.3K vs 16). Pixel 3D's advantage is review sentiment (73% vs 62%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KIRI Engine sells 10 in-app purchases, starting at $9.99 per month and Pixel 3D sells 3 in-app purchases, starting at $8.49 per month. Whichever you choose, the download price is not the number that matters.
KIRI Engine holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: KIRI Engine has 1.3K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 62% of KIRI Engine's written reviews are positive against 73% of Pixel 3D's, so the app with the better star average is not the one people write more warmly about.
KIRI Engine ships an update every 3 weeks, Pixel 3D every 9 days. Both last shipped on November 3, 2026.
