All online content (companion/club competition/Initiates) stuff has been unlocked for everybody now, you can just open all the chests.
The app is still available though and I believe the mini game still works. Here is the Google Play link.
There is a companion app for Unity that unlocks all the blue (or yellow I can't remember) chests around the city.
They may have patched it out completely because it was a fucking disaster. I would avoid it if you can.

They already have the apps. Also, if the bigger games ran on mobile hardware, we would see them releasing on mobile hardware. Unless you are walking around with a mobile Xbox One, they will have to essentially develop a new game if they want to support the NX handheld.
