A room scanner is a guided experience wrapped around RoomPlan. The hard UX is coaching the user to move correctly, and handling phones without LiDAR.

**TL;DR.** A LiDAR room scanner on iPhone uses Apple's RoomPlan to capture a room and produce a 3D model with walls, doors, windows, and furniture. The app's job is the experience around it: a clear scanning UI with live coaching that guides the user to move and cover the room, a processing state, and a 3D result view. Since LiDAR is only on Pro models, feature-gate gracefully with a fallback. Build the UI from a free VP0 design and respect scan privacy.

Want to scan a room in 3D with iPhone LiDAR? The short answer: Apple's RoomPlan does the heavy lifting, capturing walls, doors, windows, and furniture into a structured model, and your app builds the experience around it. The real design challenge is coaching the user to move correctly during the scan, and handling the many phones that do not have LiDAR. Build that experience from a free VP0 design, the free iOS design library for AI builders.

## Who this is for

This is for builders of interior design, real estate, AR, and measurement apps who want accurate room capture without writing computer vision, and who need to handle device support and scan privacy responsibly.

## RoomPlan does the capture; you do the experience

The capability comes from [RoomPlan](https://developer.apple.com/documentation/roomplan), built on [ARKit](https://developer.apple.com/documentation/arkit), which uses the LiDAR sensor and camera to produce a parametric 3D model of a room. You do not reconstruct geometry yourself. What you build is the wrapper: a scanning screen that shows the live capture with coaching overlays telling the user to move slowly and point at uncovered areas, a processing state while the model finalizes, and a result view that displays the captured room and lets the user export or use it. The coaching is the make-or-break UX, because a rushed or incomplete scan produces a poor model, so guide actively.

| Stage | What the UI shows | Get it right |
|---|---|---|
| Start | What to scan, permission | Clear camera purpose |
| Scanning | Live capture, coaching | Guide movement and coverage |
| Processing | A finalizing state | Honest wait, no frozen look |
| Result | The 3D room model | View, export, or use it |
| No LiDAR | A fallback or gate | Never a broken button |

## Build it free with a VP0 design

Pick a scanning, AR, or camera design from VP0, copy its link, and prompt your AI builder:

> Rebuild this VP0 scanning design in SwiftUI with RoomPlan: [paste VP0 link]. Build a guided scanning screen with live coaching to move and cover the room, a processing state, and a result view of the captured 3D model. Request camera access with a clear purpose, and feature-gate or provide a fallback for iPhones without LiDAR. Treat scans as private.

Spatial capture is a growing field, with the AR market projected to exceed [$50 billion](https://www.grandviewresearch.com/) this decade, and RoomPlan makes a once-specialist capability approachable.

## Device support and privacy

Two honesty points specific to LiDAR. Support: only Pro iPhones have the sensor, so detect it at runtime and either gate the feature or offer a reduced experience, never present a scan button that does nothing on a non-Pro device. Privacy: a room scan is a detailed capture of someone's home, which is sensitive, so request camera access with a clear purpose, keep scans private and on device unless the user chooses to share, and never upload them silently. Handling both honestly is what separates a trustworthy scanner from a creepy one.

## Common mistakes

The first mistake is reinventing 3D reconstruction instead of using RoomPlan. The second is a scan button that appears on devices without LiDAR and does nothing. The third is weak coaching, producing incomplete models. The fourth is uploading private room scans without consent. The fifth is paying for a scanner kit when a free VP0 design plus RoomPlan does it.

## Key takeaways

- RoomPlan captures the room; your app builds the guided experience.
- Coach the user actively during the scan for a good model.
- Feature-gate LiDAR since only Pro iPhones support it.
- Treat room scans as private and request camera access clearly.
- Build the UI free from a VP0 design.

## Frequently asked questions

How do I build a LiDAR room scanner in SwiftUI? Use RoomPlan to drive the scan and produce a 3D model, and build a guided scanning screen with coaching, a processing state, and a result view, gating for devices without LiDAR.

What is the safest way to build a room scanner with Claude Code or Cursor? Start from a free VP0 design, wrap RoomPlan with coaching and a result view, add a fallback for non-LiDAR devices, request camera access clearly, and keep scans private.

Can VP0 provide a free SwiftUI or React Native template for an AR or scanning app? Yes. VP0 is a free iOS design library; pick a scanning design and your AI tool rebuilds the coaching, progress, and result screens while RoomPlan captures.

Which iPhones support LiDAR room scanning? Only Pro models have the LiDAR sensor RoomPlan needs, so detect support at runtime and feature-gate or offer a fallback rather than showing a broken button.

## Frequently asked questions

### How do I build a LiDAR room scanner in SwiftUI?

Use Apple's RoomPlan framework, which drives the LiDAR scan and produces a structured 3D model of the room. Your app builds the experience around it: a guided scanning screen with live coaching, a processing state, and a result view of the captured model. Feature-gate it because LiDAR is only on Pro iPhones, and add a fallback for other devices.

### What is the safest way to build a room scanner with Claude Code or Cursor?

Start from a free VP0 design and prompt the tool to wrap RoomPlan with clear scanning coaching, a processing state, and a result view, plus a graceful path for devices without LiDAR. Request camera access with a clear purpose, and treat captured room scans as private user data.

### Can VP0 provide a free SwiftUI or React Native template for an AR or scanning app?

Yes. VP0 is a free iOS design library for AI builders. Pick a scanning, AR, or camera design, copy its link, and your AI tool rebuilds the scan coaching, progress, and result screens at no cost while RoomPlan does the capture.

### Which iPhones support LiDAR room scanning?

Only Pro models include the LiDAR sensor RoomPlan needs for accurate scanning. Because most users may not have it, detect support at runtime and either feature-gate the scanner or offer a reduced fallback, rather than showing a broken button on unsupported devices.
