The best iPhone 3D scanner app is the one that exports the data your next tool needs. Choose LiDAR mesh for connected surfaces, RoomPlan for structured rooms, point cloud for depth samples, Object Capture for individual objects, or Gaussian Splatting for a photoreal spatial scene. Check device support and pricing limits before you scan.
Current Voxelio pricing
Voxelio is free to download and offers optional Voxelio Pro subscriptions as in-app purchases. Prices and availability vary by storefront, so use the current App Store listing—not an old comparison article—as the source of truth.

Which iPhone 3D scanning workflow should you choose?
Start with the deliverable, not the app-store category. “3D scan” can mean a polygon mesh, an editable room layout, millions of colored points, a photogrammetry object, or a splat scene. These outputs are not interchangeable, even when one app can capture all of them.
Your goal
Choose
Typical output
Connected room or environment surfaces
OBJ + MTL, with optional textures
Structured walls, doors, windows, and furniture
USDZ and structured room data
Technical depth samples rather than surfaces
PLY point cloud
A standalone product or small object
USDZ object model
A small photoreal spatial scene
Trained splat and calibrated source bundle
Calibrated camera footage for another pipeline
HEVC video and camera data
Is a free iPhone 3D scanner really free?
Usually, “free” describes the download—not every saved project or export. Before investing time in a capture, check the current listing or in-app purchase screen for scan limits, export restrictions, resolution limits, watermarks, cloud-processing credits, and subscription terms. A scanner is only useful if you can move the result into your real workflow.
Voxelio is free to download and offers optional Pro subscriptions. You can start scanning without an account, and scan files stay on the device. We do not quote a fixed price here because Apple displays regional prices and those prices can change.
Does every iPhone support every 3D scanning mode?
No. Hardware and Apple framework support determine what an iPhone can capture. LiDAR scene reconstruction requires a compatible LiDAR-equipped device. RoomPlan uses Apple's room-capture framework. Object Capture and synchronized MultiCam video also depend on supported hardware and operating-system capabilities. A non-LiDAR iPhone may still run camera-based workflows, but it cannot produce the same live LiDAR mesh or depth data.
Check the current App Store compatibility section on the exact iPhone you plan to use. For the underlying platform behavior, Apple documents both ARKit scene reconstruction and RoomPlan.
Which iPhone 3D scanner apps are worth comparing in 2026?
The options below serve different jobs. This is a comparison of published capabilities and requirements, not a hands-on accuracy benchmark. Check the current app listing and export screen before a paid project.
| App | Strongest fit | iPhone requirement | Output and practical limit |
|---|---|---|---|
| Voxelio | One workspace for room, LiDAR mesh, point-cloud, object, and splat workflows | iOS 18 or later; LiDAR, RoomPlan, Object Capture, and MultiCam modes require compatible hardware | The current listing describes OBJ mesh, PLY point cloud, USDZ/JSON RoomPlan, USDZ Object Capture, and SPZ splats where supported. Free to download with in-app purchases; check the export and scan limits in the app. |
| Polycam | Broad format choices and floor-plan workflows | Its LiDAR Space Mode needs a LiDAR iPhone; Polycam also documents a non-LiDAR Space Mode | Its help center lists mesh and floor-plan formats by mode and plan. As documented there, the free tier's export is limited to GLTF; point-cloud and many other exports require paid tiers. |
| Scaniverse | Quick mobile meshes and Gaussian splats | Niantic supports iOS devices; check its current app listing for the exact model and OS | Niantic documents on-device mesh and splat processing and SPZ export. Check the current plan and export choices before selecting it for a production pipeline. |
| RealityScan Mobile | Photo-based models of individual objects without a LiDAR requirement | Epic's App Store listing says iOS 16 or later and no special scanning hardware | Epic documents image capture and model export; its iOS project files use OBJ. It is an object-photogrammetry path, not a substitute for a structured RoomPlan layout. |
For a non-LiDAR iPhone, start with an app's photo-based capture or its documented non-LiDAR mode. For a LiDAR-equipped iPhone Pro, compare a sample room in Voxelio, Polycam, and Scaniverse using the same lighting and destination format. For a small object, compare photo coverage and final OBJ/USDZ needs before picking RealityScan or an Object Capture workflow. Apple says RoomPlan requires LiDAR, so a general app compatibility listing does not mean every mode works on every iPhone.
What should you compare before choosing a scanner?
Use a short workflow test instead of comparing feature counts. Scan one representative room or object, export it, and open that file in the software you actually use. Evaluate the complete path from capture to usable output.
- The exact export format your next tool accepts
- Whether the selected mode requires LiDAR, RoomPlan, Object Capture, or MultiCam support
- Whether reconstruction happens on the phone, in the cloud, or on a desktop
- Limits on saved scans, exports, resolution, or commercial use
- Whether raw geometry, textures, depth, camera poses, or editable room data are included
- How the app handles privacy, account storage, and deletion
When is LiDAR mesh the right choice?
Choose LiDAR mesh when connected surfaces and scale matter more than photoreal detail. It is a practical option for room references, site documentation, rough measurements, layout planning, and bringing an environment into a 3D tool. Voxelio's Mesh mode exports OBJ + MTL and can include classification colors, neutral geometry, or real-color texture output depending on the selected workflow.
When is RoomPlan better than a mesh?
Choose RoomPlan when you need recognized architectural elements rather than a dense web of triangles. Walls, doors, windows, openings, and furniture categories are more useful for floor-plan and interior-layout work. A mesh preserves surface shape; a structured room model preserves semantic room elements. Some projects benefit from capturing both.
When should you use point clouds, Object Capture, or splats?
A point cloud is useful when you want depth samples for inspection, measurement, or a downstream technical pipeline. Object Capture is designed for a bounded object that you can photograph from many angles. Gaussian Splatting is useful when view-dependent visual appearance matters and the goal is a navigable scene rather than a conventional CAD-like surface model.
Voxelio keeps these as separate modes because capture guidance, processing, and outputs differ. Its Gaussian workflow is designed for small scenes and can train on the iPhone; processing time still depends on scene size, device performance, storage, and thermal conditions.
How do you get a better scan?
- Choose the output before starting the capture.
- Use even lighting and avoid reflective, transparent, or moving surfaces where possible.
- Move slowly, keep overlap between views, and watch the app's tracking feedback.
- Capture the subject at a scale appropriate for the selected mode.
- Inspect missing geometry or blur before leaving the location.
- Export a test file and open it in the destination tool before scanning a full project.
So, what is the best 3D scanner app for iPhone?
There is no universal winner. The right choice is the app that supports your iPhone, captures the required type of data, exports a compatible format, and has limits you understand before the job begins. Voxelio is designed for people who want several spatial-capture workflows in one iPhone app, including mesh, point cloud, RoomPlan, object, Gaussian Splatting, and calibrated video capture.
