Why would you want your phone to tell you when a friend logged on?
you can also check who's online without the need for an app.....
us.playstation.com > Community (at the top of the page) > Friends > List by Online Friends.
you can do it with your smartphones browser, bookmark it, and click refresh.
no need to beg for an app
Oh man....that's so much easier! Thanks.....wrong!!!
I don't recall begging for an app...I just asked.

And a better, easier solution.
Don't be a smartass
