3D Object Capture|Room Scanner vs 3D Topology Optimizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
3D Object Capture|Room Scanner
Create high-definition 3D models from real-world objects using AR guidance. Models can be exported in various formats for sharing, AR viewing, or 3D printing. Requires a compatible iPhone or iPad Pro.
- Generate high-definition 3D models
- Follow AR instructions for scanning
- Export in .usdz, .obj, or .stl formats
- Share models via file, link, or Sketchfab
- Local model generation on device
- Preview models in AR

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.
3D Topology Optimizer
Read full descriptionHide full description
3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength — entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES • Automatic hole detection — cylindrical bores are recognized and automatically protected from the optimizer • Calculated entirely on-device — your geometry and load cases never leave your device • High-resolution STL export for 3D printing or CNC machining • Built-in parametric templates (bushings, brackets) to get started without any CAD file • Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.

Verdict
The clearest difference is ads: 3D Object Capture|Room Scanner at none against 3D Topology Optimizer's shown. 3D Topology Optimizer's advantage is update cadence (every 6 days vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 3D Object Capture|Room Scanner sells 1 one-off in-app purchase and 3D Topology Optimizer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
3D Object Capture|Room Scanner ships an update every 3 months, 3D Topology Optimizer every 6 days. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
