I programmed a little AoS Mission Helper App for Android a while ago which my friends and I use to generate our games.
I'll upload the app for anyone to use for free on this forum once I can make sure I don't violate any rights of Games Workshop.
Since I've checked everything thoroughly and all the art is either copyright free (background image) or self-made (the rest) this app should not violate any rights.
You can get your free Android App here:
