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.

DepthTag

Features
Read full description

DepthTag turns your iPhone Pro into a precise measuring tool. Point the camera at anything, tap, and it reads the exact distance using the LiDAR scanner. No tape measure, no guessing. REQUIRES A LiDAR SCANNER DepthTag needs the LiDAR sensor found on iPhone 12 Pro, 13 Pro, 14 Pro, 15 Pro, 16 Pro, and later Pro and Pro Max models. It does not work on non-Pro iPhones. POINT, TAP, MEASURE - Tap anywhere in the camera view to tag the exact distance to that point - A live reticle shows the distance under the crosshair as you move - Tags stay pinned in space, so you can capture several at once FOUR MEASURE MODES - Ruler: the straight-line distance between two points - Height: measure vertical clearances and object heights - Area: outline a surface and read its area - Tape: trace a winding path and get its total length BUILT FOR REAL WORK - Metric or imperial units, switch anytime - Floor clearance readout for quick height checks - Save, label, and revisit every measurement - Export your measurements when the job is done ON DEVICE AND PRIVATE - All depth processing happens on your iPhone - Nothing is uploaded, no account, no tracking - Works offline, anywhere Whether you are checking if furniture will fit, sizing up a room, planning a shelf, or measuring on a job site, DepthTag gives you fast, LiDAR-accurate numbers without unrolling a tape measure.
