Did a bit of googling and this came up: https://canvas.io/. But, it's not for Android.
Edit: the Canvas.io software really wants the latest iPhone or iPad devices with LIDAR scanners built-in. It will supposedly run on lesser hardware, but with greater error in the constructed 3D map. Fine for a sample to get an idea of whether or not it might work for you, but not really enough to actually use for anything useful.

But IMO, this still isn’t good enough. It’s a huge improvement over the corner mode, which is what you have to use if you aren’t using a device with a LIDAR sensor, but it’s still not enough.
I’m still looking.
