Best 3D Room Scanner Apps in 2026
A 3D room scanner app can produce a measured floor plan, a textured model or a visual walkthrough. Start with the file you need: a model that looks convincing is not automatically a dimensioned plan you can use for a renovation.
We publish Room Scanner. This comparison uses the providers' product pages linked below, checked on 29 September 2026. We have not run a comparative accuracy or speed test. For a closer look at dimensioned plans, see our guide to floor plan scanner apps.
The Three Ways to 3D-Scan a Room
| Method | How it captures | Useful output | What to check |
|---|---|---|---|
| LiDAR | A depth sensor measures distances; the app reconstructs surfaces or room geometry | A model or floor plan, depending on the app | Supported hardware, missed features and dimensions that need correction |
| Photogrammetry | Software reconstructs geometry from overlapping photographs | Textured models of objects or spaces | Image coverage, lighting, scale and the exported model |
| 360 capture | Panoramic images record the surroundings | Walkthroughs or input for a reconstruction service | Whether the service supplies measured geometry as well as imagery |
These methods can be combined. Choose the capture mode and output together: a textured mesh, a Gaussian splat and an editable floor plan serve different purposes. Check the deliverable in the software where you intend to use it.
Comparing the Leading 3D Room Scanner Apps
| App and provider source | Capture and platform | Workflow to consider | Export check |
|---|---|---|---|
| Room Scanner | LiDAR on supported iPhone/iPad; manual dimensions on compatible Apple devices | Create and edit a 2D plan and 3D model; add furniture or survey details | PDF, PNG, USDZ and JSON; Pro adds CAD and report formats. Check the current export sheet for access. |
| Polycam | Several capture modes, including spatial and object capture | Models, floor plans and walkthroughs | Confirm the output and subscription for the chosen capture mode |
| Scaniverse | iOS/Android capture with a web workflow | Classic for individual objects/small spaces; the newer service for team and large-area reconstruction | Check which experience you are using; the newer workflow uploads scans for cloud processing |
| KIRI Engine | Photo, LiDAR and Gaussian-splat modes, depending on device | Object and visual 3D capture | Match the capture mode, file format and processing requirements to your task |
| Metaroom | LiDAR-enabled iPhone Pro/iPad Pro | Room/building capture with review in Metaroom Workspace | Workspace supplies CAD/model exports; access depends on its trial or subscription |
| magicplan | iOS/Android; available capture tools depend on hardware | Floor plans connected to field documentation and estimates | Check the plan/report format and integrations required by your team |
The links identify each provider's current information. A free download does not necessarily include every export, and support for one platform does not mean all capture modes are available there.
Which one to actually pick
For a dimensioned plan, compare Room Scanner with the floor-plan workflows in magicplan and Metaroom. For textured objects or visual reconstruction, review the relevant modes in Polycam, KIRI Engine and Scaniverse. For a remote property walkthrough, check the tour or panoramic workflow and how viewers will access it.
In Room Scanner, you can review the plan, correct dimensions and export it for the next step. See our room measurement workflow and capture and editing guide. Choose the app by its actual output and your review process, rather than a claim that one method is always more accurate.
What Accuracy Can You Expect?
There is no single accuracy figure that applies to every phone, app, room and export. Capture conditions, reconstruction, editing and your measurement reference all affect the result. We have not measured the apps in this table under the same conditions, so this guide does not rank their precision.
A 2021 iPhone LiDAR study reported results for small objects and a coastal cliff. Those experiments do not establish the accuracy of a complete floor plan made with any of the apps compared here.
Use an independent check before relying on a dimension:
- Pick dimensions that matter to your task, including the relevant openings and clearances.
- Measure between the same reference points with a suitable independent tool.
- Compare the measurements, investigate differences and correct or recapture the plan as needed.
- Export the file and check its units, scale and labels in the receiving software.
Our measurement-check guide and calculator shows how to compare a captured length with a reference. Passing a few checks does not certify the whole plan.
| Approach | What it contributes | What still needs checking |
|---|---|---|
| Room-scanning app | Connected room geometry and a digital plan or model | Missing features, dimensions, joins and export scale |
| Laser distance meter | Individual reference readings | Instrument specification, endpoints and transcription |
| Tape measure | Direct measurements of selected features | Consistent endpoints, reading and recording |
| Professional survey | A deliverable agreed for a defined purpose | The scope, required tolerances and intended use |
Do You Need a LiDAR iPhone?
You need a LiDAR-equipped device for a LiDAR capture mode. Check the exact device and operating-system requirements on the provider's listing before installing or subscribing.
Room Scanner also lets you enter dimensions for a rectangular or L-shaped room on a compatible device without LiDAR. That creates a plan from measurements you supply; it is not automatic scanning. Photo-based capture is another option for visual models on supported devices. Pick the method that produces the output you need.
FAQs
What is the best 3D room scanner app?
Choose by deliverable: a dimensioned plan, a textured model or a walkthrough. Use the provider table to shortlist tools, then try a representative room and export a sample into your intended software before buying a plan.
Can I 3D-scan a room without LiDAR?
Some apps reconstruct a space from photographs or other camera capture. For a floor plan, you can also enter independently measured dimensions in an app such as Room Scanner. Manual entry and automatic scanning are different workflows.
What is the difference between a 3D room scan and a floor plan?
A 3D scan represents a space in three dimensions. A floor plan shows it from above, usually with walls, openings and dimensions. Room Scanner produces a plan and model from the same room data; check that the exported representation contains what your recipient needs.
How long does it take to 3D-scan a room?
Allow time for preparation, capture, processing, measurement checks, corrections and export review. The total depends on the room and workflow. This guide has no timed comparison that supports a fixed minutes-per-room promise.
Are 3D room scanner apps accurate enough for renovation?
A reviewed plan can help with layout discussions and preliminary planning. Check critical dimensions independently before ordering fitted items or committing to work. Where a project needs a professional survey or certified drawing, agree that deliverable with an appropriate professional.
Can I export a 3D room scan to CAD?
Some apps provide CAD exports. Room Scanner offers DXF and SVG with Pro, alongside USDZ for 3D output. Verify format support, units and scale in your destination software before relying on the file.
Which is better, LiDAR or photogrammetry?
The answer depends on the capture conditions and output. Compare a representative result, its measurement checks and the work needed to make it usable. The presence of LiDAR alone does not establish that one app's finished model is more accurate than another's.
