       | Which apps are good to try on iOS?

         | PolyCam is apparently not free but considered one of the best.
         | I used 3D Scanner from Laan labs (& it's a free app. No ads
         | thankfully). I used it to build a few dataset for NeRFs based
         | on MIPNeRF. The data quality seemed pretty fine. I use a iPad
         | Pro with M1 btw.

       | faster now, and the auto-alignment works better.
       | 
       | Open Drone Map does much the same thing, by different means. You
       | feed a few dozen pictures from your drone into the program and
       | get out something that looks like Google Earth. Open source, too.
       | Machine learning techniques have helped the alignment and camera
       | calibration problems substantially.
       | 
       | It's still a niche thing, like spherical photography.

         | 
         | For example, exposure bracketing and stacking to get HDR images
         | had to be done using dedicated software fifteen years ago or
         | so, but nowadays most cameras and phones do it without any
         | additional steps.

       | description.

       | rotating an object to capture it's faces)

           | This looks cool, but your link is to a video describing it,
           | and the app "Object Capture" doesn't appear to be in the
           | Apple App Store.

       | Why are the free phone scanning apps so far ahead of their open

       | apps work just as well on Android?
       | 
       | Because I've tried Meshroom, and while it has a surprisingly nice
       | UI, it took my desktop 3 hours to compute a relatively mediocre
       | model of a tiny part of my hallway.
