Why isn't the official PS4 App been released yet?

[Windows Central Question]

I am curious because I know of loads of people who would be happy to know this, like myself I do have the app installed on my Samsung Tablet BUT! Why should we be thrown to one side, competition has nothing to do with it either. Commission it or don't, just give us an answer.

Most likely because Microsoft and Sony are rivals in the gaming industry.
