Something similar to Bitmap 2 Material/Alchemist but as an Android/iOS app.

Since a phone has both a camera and compute abilities there should be an Allegorithmic app that allows us to point our phone at any nice looking surface from the outside world and generate a material from it without the need to bear some complicated hardware and getting back at home sorting all of these pictures one by one on desktop computer.

Then after taking all the picures needed the app would be able to generate a material either by combining all the scanned data locally or why not sending all the pictures to a render farm or any remote machine and then sends the finished material back to our allegorithmic material vault. The tech build with substance Alchemist would also be useful for that application.
