iPhone LiDAR Scanner
An iPhone room scanner is only possible on models that include LiDAR. On those devices, this app can help turn a walk through the room into a measured floor plan.
Scan a house with iPhone, one room at a time
Walk the first room, review the plan, then continue. A whole-home scan is a series of room scans kept in one project, not a single magic pass through every wall.
How to scan a room into a 3D model
Move calmly, keep walls in view, and give openings a clear look. After the scan, open the plan in 3D and check whether doors and furniture still make sense.
