Arkham Horror App?

By angelfromanotherpin, in Fan Creations

So, the X-Com boardgame uses an app to manage a lot of game functions, and it actually works really well. How difficult would it be to make a similar app for Arkham Horror? You could put all the encounter decks in it, saving considerable table space. You could also put the Mythos deck in it, and have it walk you through the Mythos phase, making sure you did it in the correct order and didn't miss anything.

These apps, believe or not, actually already exist.

I use the Arkham Companion myself.

Where is Arkham Companion and how do I get it?

I found it on Google Play, I think. I use an Android phone.
