I wasn't even aware there was a companion app. Something to track war table missions or something I presume?
There's a little blurb on it in the MP FAQ on dragonage.com:
Is any sort of app planned for Dragon Age multiplayer?
· BioWare understands that players can expend a lot of time going through their inventory and crafting new items. We also understand that when you are online with your friends, you want to get into action quickly. With these needs in mind, we developed the Inquisition HQ. There, you will be able to access all of your MP characters and their inventory. You will be able to change your loadout, salvage items, and craft new items. You can do all that on the go because it will run on PCs, tablets, and smartphones. We will give more details about Inquisition HQ in the following months.
Not much info beyond what EP said in the first post though.
And, I'd like to see a little preview if possible, please.
