Room Scan offers a whole new way to capture & store the measurements of a room, then interact and understand the space you're working with. With Room Scan, you can scan & save an interactive 3D model of a room, straight to the job diary, then get instant measurements to help scope the job, or add markups to communicate details such as points of interest or installation locations. Room Scan requires iOS 16 or later, and an iPhone or iPad with LiDAR technology e.g. recent iPhone Pro & iPad Pro models (see [here](/help-center/tips-trick-more/more/servicem8-ios-device-compatibility) for more details). ## How to start a Room Scan 1\.
