Which devices can scan rooms?

Scanning requires a LiDAR-equipped iPhone that supports RoomPlan. Some Pro and Pro Max models include this hardware; standard iPhones may not. The app checks device compatibility. Other devices can view saved records and the example plan. Use meters, millimeters or feet and inches, including fractional-inch entry. Scanning requires iOS 17 or later. Buying Pro does not add scanning hardware. The app is intended for indoor residential spaces on a single floor.

How do I make a site record?

  1. Follow the scanning guidance and save each room when you finish it.
  2. Review the same room in Floor Plan, 3D Model and Data. Use wall references to find corresponding dimensions.
  3. Check critical dimensions with your own measuring tools and enter the values manually. Scan estimates and checked measurements remain separate.
  4. Add photos and notes, then mark their positions manually on the plan.
  5. Preview and export a PDF or high-resolution PNG. Use the iOS share sheet to send it or save it to Files. Recipients do not need RoomMark.

Why do scan estimates differ from checked measurements?

Phone scans are estimates and can be affected by lighting, obstructions, reflections and how you move the device. Verify critical dimensions with appropriate measuring tools. Entering a manual value does not reshape the model or recalculate area. The app does not automatically import readings from external laser measuring devices.

What if scanning is slow or walls are missing?

Use adequate lighting, move slowly, and bring walls, corners, doors and windows into view. Follow the system guidance to revisit missing areas. Mirrors, glass, clutter and poor lighting may require more time. Review key walls and openings before saving; rescan the room if needed.

What if saving or exporting fails?

Keep the current screen open, retry as prompted, and check available device storage. If the issue continues, email support with the exact message and steps. Avoid uninstalling while troubleshooting until you have confirmed the records are saved or kept necessary copies. PDF and PNG files can be shared and viewed but cannot restore an editable project.

Trial, Pro and restoring purchases

Before your first scan, edit or report export, you can claim a 7-day free trial. The trial starts only after you confirm the free offer with Apple; opening the app, viewing the sample or canceling does not start it. There is no automatic charge when it ends. You can still view, organize, archive, back up and import saved records afterward. Choose annual or lifetime Pro to continue scanning, editing and exporting.

Yearly access renews annually and can be canceled in Apple subscription settings. Lifetime access is a one-time purchase with no automatic renewal. The App Store purchase screen shows current prices and terms.

Sign in with the Apple Account used for the original purchase and tap Restore Purchases on the paywall. Canceling a subscription generally preserves access until the end of the paid period. Request refunds through Apple's Report a Problem service.

How do I organize and back up a project?

Open Projects to search, use folders and project types, or archive completed jobs. Archived projects can be restored. Export an editable project backup to Files before deleting important records or uninstalling the app. Backups include room models, photos, checked measurements, points, routes and saved report versions. Importing creates a new project copy and leaves existing projects unchanged. PDFs and PNGs cannot restore an editable project.

Can I change languages, units or report size?

In Settings and Help, choose English, Simplified Chinese or Follow System. Change the dimension units to meters, millimeters or feet and inches. In Export and Share, choose A4 or US Letter. Save a report version when you need to keep a copy that will not change with later project edits.

What do installation points and routes do?

Place access points, data outlets and cabinets manually. Record mounting heights from the finished floor, status and notes. Draw cable routes and record horizontal estimates, vertical runs, slack and final checked lengths separately. These records help explain an installation plan; they do not measure Wi-Fi signals, predict coverage or replace an on-site check.

Are my records uploaded?

Scans, plans, dimensions, photos and notes stay on your device. The app does not upload them to the developer or third-party AI. System backups may include local files. Files you choose to share are passed to your chosen recipient. See the Privacy Policy.
