While you wait for shapr3d You can try out Magicplan for that. It’s possible to export to shapr3d as Dxf and extrude the drawing or export as OBJ
I got my Iphone 12 today. I´ve only tried 3D scanner app from Laan Labs. I did a quick scan of my living room and did an untextured obj export to shapr3d via airdrop.
