Companion Apps for Age of Triumph

Are there any "must have" sites/apps that you all use. Even in this most recent update. I left 3 years ago and barely even understand some of the new systems etc. But out of a desire to not waste time or effort on the old apps I used I want to confirm the ones I used years ago here and also ask for any new ones.

I know the game now has an awesome "use the vault anywhere" system now so I imagine this has become a tad obsolete. I still wouldn't mind using it especially if the QoL is still better than the in game systems. But am so out of the loop I don't want to waste time in/on it unless it's still confirmed good.

I used a few different pages here and want to make sure this is still worthwhile as well.

Thank you ahead of time for any input.

So what are your recommendations?
