Turn your iPhone or iPad into a powerful 3D scanner. Point at an object, follow the AR guidance, and get a textured 3D model — built entirely on your device. No account. No cloud processing. No subscription. SCAN OBJECTS Perfect for artworks, hand-crafted items, toys, anime figures, and more: 1. Point at the object — the app gauges its size and places a bounding box you can adjust 2. Slowly circle the object — photos are taken automatically; just light up the ring of white dots 3. Follow the guided passes with short tutorial videos: flip the object, or scan from a lower angle and the top 4. Generate the model on your device and preview it in AR 5. Share it in a few taps SCAN ROOMS — TWO WAYS • Floor plan: walk through your space and watch walls, doors, windows, and furniture get outlined live. Scan several rooms and merge them into one structure. You get an interactive 3D model plus a measured 2D floor plan: floor area, wall lengths and height, door and window counts — tap any piece of furniture for its dimensions. • Photo-textured room mesh (LiDAR): capture a true 3D mesh of your room with photos baked in as seam-free textures. The app shoots high-resolution (up to 4K HDR) photos hands-free while a color tint shows what you have covered. Then drive a hovering robot through your scan in third person, with real collision against your scanned walls and furniture. Exploring is free; exporting and sharing room meshes requires Pro. EXPORT & SHARE • .usdz — mobile friendly, opens straight into AR Quick Look • .obj with textures — for professional 3D software (Pro) • .stl — for 3D printing (Pro); room meshes export with hole filling, smoothing, and a detail slider • Share via Messages, Mail, AirDrop, or save to Files • Create a public iCloud Drive download link anyone can open — no app needed (iOS 26 or later) • Publish to Sketchfab and share your model as a link or QR code CAD-STYLE FLOOR PLAN EXPORTS • PNG image or a CAD-styled multi-page PDF report with dimension lines, a scale bar, and wall/object schedules (2 free exports included) • Layered DXF that opens in your CAD software (Pro) • Plan your furniture: draw annotation boxes with exact real-world sizes on the floor plan — they turn red if they would collide with walls or existing furniture (Pro) MEASURE See the real-world width, height, and depth of your scans, and measure point-to-point on 3D models and 2D floor plans, in your local units (2 free measuring sessions included). AND MORE • Import 10 or more of your own photos from Photos or Files and reconstruct them into a 3D model on-device (Pro) • Try it instantly with a free downloadable example capture • Transfer captures to the companion Mac app for maximum-detail models • Localized in 16 languages • Pro is a one-time purchase — no subscription, works on all your devices REQUIREMENTS Scanning requires a LiDAR-equipped iPhone Pro or iPad Pro. Captured data stays on your device unless you choose to share it.
