How do I scan multiple floors with the Metaroom Scan App? 

The Metaroom Scan App makes it easy to capture multi-floor spaces in a single scanning session. Whether you’re scanning a two-floor house or an entire building, all you need to do is scan room by room — floor by floor — using the multi-room scanning functionality.

Follow these steps to scan multiple floors with the Metaroom Scan App:

1. Open the Metaroom Scan App on your iPhone Pro or iPad Pro.
2. Tap Add Scan to begin a new project.
3. Start scanning the first room on the ground floor. Move slowly, keep your distance from walls and furniture, and scan all corners.
4. Once you’ve finished scanning the first room, tap Finish Section.
5. On the review screen, check that all key elements are visible. Tap Rescan if you’re not satisfied with the result, or Add Section to scan the next room on the same floor.
6. Repeat this process for all remaining rooms on the floor.
7. Once you’ve finished scanning all rooms on the current floor, tap Add Section and walk to the next floor while keeping your device upright.
8. At the new floor level, tap Start Section to begin scanning rooms on the next floor.
9. Scan each room individually, tapping Finish Section after each one, and Add Section to continue to the next room.
10. After capturing all floors and rooms, tap Finish Scan.
11. Great work! Keep the Metaroom Scan App open while the model uploads to the Metaroom cloud. Depending on the scan size and your internet connection, this usually takes a couple of minutes.
12. Once uploaded, you can access your 3D model from the Metaroom Scan App → Projects, or from Metaroom Workspace → Projects.

Keep in mind: to scan a new room or floor, always tap Add Section first, then move to the desired location. Once there, tap Start Section to begin scanning. Following this order is important — it helps the app better understand your position, resulting in more accurate stitching of all rooms and floors in the final 3D model.

Essential scanning tips

To ensure smooth and accurate scanning of multiple floors, please keep in mind the following recommendations:  

• We recommend enabling the Tracking Assistant feature in the Metaroom Scan App — it provides real-time feedback on your movements and environmental conditions to help ensure a more accurate scan.
• Hold the device upright at all times, even when walking between rooms or floors. The camera uses SLAM tracking to stitch rooms into a cohesive 3D model.
• Keep the camera lens clear and avoid covering it when moving between rooms or floors.
• Close doors where possible to help the app define room boundaries more precisely.
• Maintain steady movement and scan in a circular path to close the loop before finishing a room section.
• Plan the order of your scan sections in advance so you don’t miss any areas, especially in larger spaces.
