The new iPhones and iPad are more powerful than ever. Developers are coming up with apps to take advantage of all that technology inside. Take LidarCad for iPhone: it is a LiDAR scanning app that can be used to scan environments, capture point clouds and measure length/area/volume.
This app can give you scans in feet and meters. It comes with a whole host of 2D drawing tools too. LidarCad is designed to work with iPhone and iPad models that have a LiDAR sensor. It saves scans as point clouds or meshes. The app supports DWG and DXF files.[where to get it]
