I just uploaded an app to extras devel, it's called macoui. this app gives you the name of the organization from a MAC adress, you enter the first 6 characters and then press the button Get Org, it supports landscape and portrait mode, the info is taken from this file:

standards.ieee.org/develop/regauth/oui/oui.txt

I downloaded it and it's inside the app, so
you can use it without internet, I hope someone find a good use for this!
