I recently 3D scanned an area of my property (about 250 feet long) with my iPhone in order to make a map. Polycam was the winning app (Scaniverse and SiteScape did not work as well). Do not underestimate the sheer amount of walking around and aiming your phone that this technique requires. A 5m range is not much, and in some cases the effective range seems to be less than that. If you just want a to-scale image of an area, you can stop after "Capturing the model" and take a screenshot of your captured scan, but it's still a lot of work.
