Turn spaces and objects around you into 3D models. Capture rooms with rear LiDAR on supported devices, or capture nearby objects with the front TrueDepth camera. See geometry coverage as you scan, review your capture, then calculate the model on your device. Rotate, zoom, measure and explore models. Crop and smooth geometry, reprocess saved captures, and export OBJ, PLY, STL and USDZ files. Original capture data stays on your device. Switch between English and Simplified Chinese inside the app. Use the volume buttons to start and stop Object capture. No account, ads, subscriptions or in-app purchases. Scene capture requires LiDAR; Object capture requires TrueDepth. Glass, mirrors and low-reflectivity surfaces may be incomplete. Measurement accuracy depends on capture conditions. Photo-only reconstruction is not supported.
