Scan4D is a professional-grade reality capture app for iPhone and iPad. It turns your device's LiDAR sensor and camera into a powerful 3D scanner, capturing detailed meshes, depth maps, and camera poses for downstream reconstruction, photogrammetry, and spatial computing. FULL MODE (LiDAR devices) • Real-time mesh reconstruction with live wireframe overlay • 16-bit depth maps captured at adaptive frame rates • Scan capacity metrics: polygon count, drift tracking, session duration • Interactive 3D mesh preview with camera-sampled vertex coloring • Privacy filtering: person segmentation removes humans from meshes, face blurring in RGB exports LITE MODE (all devices) • RGB frame capture with ARKit camera poses • Server-side photogrammetry via exported image bundles • Automatic detection — no configuration needed TIME-SERIES SCANNING • Group scans by Location and re-scan the same space over time • "Extend Scan" loads a red ghost-mesh overlay of previous captures • Adjacent stitching: scan neighboring areas with shared coordinate frames • ARWorldMap relocalization for precise alignment between sessions FLEXIBLE EXPORT FORMATS • Scan4D: Full bundle with metadata, relocalization map, images, depth, and camera data • Polycam: Raw data import compatible with Polycam • RAW: Nerfstudio/COLMAP-compatible transforms.json + images + depth • OBJ / PLY / USDZ: Native mesh formats for MeshLab, Blender, and iOS Quick Look SERVER INTEGRATION • Configure any HTTP(S) upload endpoint in Settings • Direct PUT upload with live progress tracking • Save to Files or AirDrop for offline workflows • Compatible with self-hosted reconstruction pipelines DEVELOPER MODE • Front/back camera switching for testing privacy features • Synthetic IMU, camera, and depth injection for Simulator testing • Vertex mapping diagnostics and debug overlays Designed for researchers, 3D scanning professionals, and spatial computing developers who need raw, high-fidelity sensor data with full control over the reconstruction pipeline. Requires ARKit-capable device. LiDAR-equipped iPhone or iPad Pro recommended for full functionality.

Your computers and PC games, on iPhone and iPad. Use compact touch controls on iPhone or a spacious workspace with keyboard and pointer support on iPad. On iPhone Duo with iOS 27.1, unfold for a larger desktop or partially fold for a split desktop and black trackpad workspace. FOUR WAYS TO CONNECT • Mac Screen Sharing: Apple High Performance streaming on compatible Apple-silicon Macs. Use a physical or virtual desktop, with host-supported computer audio. Choose all physical displays or an individual monitor. • RDP: access supported Windows and Linux desktops with Unicode text clipboard and host-supported audio. Choose desktop sizes up to 4K and an audio-quality preference. • VNC: connect to compatible Mac, Windows and Linux servers. Adjust image quality and compression on supporting servers. Select individual monitors when the server supplies their layout. • Sunshine: stream your desktop and PC games from a separately installed Sunshine host. Pair a compatible controller with your Apple device to send buttons, sticks and triggers. HEVC or H.264 video, stereo audio, and custom stream size, frame rate and bitrate controls are included. CONTROLS THAT FIT Click, drag, scroll and type. Use touch gestures, a scrollable extra-key strip, standard shortcuts and supported physical keyboards and pointing devices. Fit the desktop or zoom in. Keep session controls close without covering your workspace. Built-in setup and gesture guides help you get connected. START FREE Save one computer and use every connection type, full connection settings, supported sound and text clipboard, standard shortcuts, and backup export. No ads, session timers or artificial quality limits. MORE ROOM WITH PRO Unlimited saved computers, optional iCloud setup sync, custom and pinned shortcuts, reusable text, named control presets, folders, notes, desktop captures and connection-library import. Choose monthly, yearly or a one-time lifetime purchase. Pro works across iPhone, iPad and Mac using the same Apple Account. Existing lifetime owners keep access. Restore Purchases is available on the Pro page. YOUR CONNECTION, YOUR SETUP No Farroom account, relay or Farroom helper app. Your computer needs a supported remote-access server and a reachable network address. Away from home, you can use a separately installed private-network app such as Tailscale. Farroom does not provide a VPN. KNOW YOUR CONNECTION Requested video size, frame rate and quality depend on the host, network and viewing device. Sunshine streams its configured Desktop entry; display selection is managed on the host. Sunshine has no clipboard sync, controller rumble or microphone forwarding, and typed text assumes a US keyboard layout. VNC has no audio and its clipboard is limited to Latin-1 text. RDP audio depends on the server; Windows Home cannot host built-in RDP. Linux support depends on its desktop and server. Clipboard transfer is text only. Mobile operating systems may suspend background sessions. Passwords stay in device Keychain when saved. Optional iCloud setup sync excludes passwords, certificate approvals, desktop images, audio and clipboard contents. SUBSCRIPTIONS Monthly and yearly Pro renew automatically unless canceled. Eligible yearly subscribers receive a 14-day free trial. The app displays local prices and eligibility before purchase. Manage or cancel through Apple Account subscriptions. Expiry returns to Free without deleting saved data. Lifetime does not renew. Privacy: https://farroom.danielren.tz/privacy/ Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
