I’ve seen a few apps but haven’t come across anyone really pushing or experimenting with the iPhone as a 3D scanner……
….so it’s a good job I have!
Things you need to know: The LiDAR Scanner is really good for large rooms and objects but you need to use the TrueDepth camera on the front for smaller objects and details.
For lidar I use Scaniverse for car-sized objects and Smartpoint for really large scans. Both will give you decent results. See here for some quality examples (not my work)

For TrueDepth I swear by Capture by Standard Cyborg. It’s free and the easiest to get to grips with. There are other apps like Heges which give you finer control over the process but I have found the results haven’t been as good. The issue with using TrueDepth is of course you need to point the front of the iPhone at an object to scan it meaning you cannot see the results at the same time! I have found looking at the screen from a steep angle to be a good way around it. Heges has an iPad app that lets you use the iPad as a remote display allowing you to see the results at the same time which is pretty neat.
This is some of my work using the TrueDepth scanner and processing the resulting model in mesh lab and Fusion 360:

This took some work but I managed to combine several mesh scans from Capture into one large model for 3d printing:
