Object3D vs Precis3D

Object3D turns your iPhone into a powerful 3D scanner. Using the LiDAR sensor and Apple Object Capture, walk around any real object and get a photorealistic 3D model — processed entirely on your device. FEATURES • Guided capture with real-time tips (distance, lighting, motion) and a progress ring • On-device 3D reconstruction — your photos never leave your iPhone • Interactive 3D preview with orbit and zoom • Real-world measurement — distance, angle and multi-point paths, in cm, mm or inches. Measurements are saved with the model and can be exported as a report (text or JSON) • Size calibration (Pro) — measure one dimension with a ruler and every size for that model is corrected by the same ratio • Library search, sorting by date, name or size, and multi-select delete • Export to multiple formats: - USDZ for Apple AR Quick Look - GLB for the web and cross-platform use (embed anywhere) - Lossless HD GLB for professional use - STL for 3D printing - OBJ for 3D editing tools - Raw photos (only while a scan's capture frames remain — they are removed automatically once the model is built) ON-DEVICE & PRIVATE No account needed, no sign-up, no data collection. Scanning and reconstruction run entirely on your iPhone. OPTIONAL ICLOUD SYNC Turn on iCloud Sync to keep your models across your devices. Data goes only to your own private iCloud library — visible to you alone. It is off by default. REQUIREMENTS Requires an iPhone with a LiDAR scanner (iPhone 12 Pro or later Pro models).

Precis3D is a full-scale precision 3D scanning app for iOS. It uses your device's LiDAR and camera to capture physical objects in real-time, then reconstructs them into high-quality 3D models with up to 0.1–0.3mm precision. Key Features: • LiDAR + Photogrammetry Fusion: Combines depth and visual data for optimal reconstruction • Smart Capture Guidance: Real-time spherical coverage tracking with a HUD overlay • Export to Multiple Formats: STL, 3MF, OBJ, USDZ, PLY • Export Limits: 1 free USDZ export per day; premium STL/3MF/OBJ exports available via in-app purchase • Auto Frame Quality Assessment: Filters out blurry or over/under-exposed shots before reconstruction Requirements: - iPhone 12 Pro or newer (LiDAR required) - iOS 17.0+ No account required. No ads. No data collection. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
