Maybe what you want is actually a phone app? I can't give specific recommendations, but I know there are apps that will attempt to reconstruct a model from photos taken at different angles.
I have tried a few of them without much satisfaction. Usually the scans are disappointing when it comes to the detail level. I want something that I don’t have to spend a lot of time cleaning up in blender or another 3d program.
The other issue I have had is no matter how careful I am with moving the phone around the subject, often it will error out which is mind boggling frustrating. Go to quick, it errors, too slow it errors, turn to fast, errors, get mad and throw your phone - well you get the picture.
Most phone apps likely won’t reach the quality of a standalone scanner for a variety of reasons. For instance, a lot of the ones I’ve played with don’t optimize the shutter speed, which can wreck havoc when some captures contain motion blur.
That said, have you tried the free 3d Scanner App yet for iOS? Yes, you may need to clean up your scans like any other phone app, but since it also lets you use the front-facing TrueDepth sensor as well as the rear, it can return a pretty darn good scan when it can combine that TrueDepth data with the usual photogrammetry point cloud. Plus, it’s got a bunch of post-processing tools to modify your scans afterwards, like cropping out extraneous elements using a box or a sphere, selecting mesh pieces to remove/retain, etc. It’ll also export to SketchFab as well as your usual 3d printable file formats.
And no, I’m not affiliated with it; I’m just a happy user who was able to successfully use it to 3d print my doggo sleeping as well as scan some gallery exhibits.
