The apple apps are built into the operating system, but they suck. So if o say hey Siri give me directions to home it pulls up iOS maps, which is significantly inferior to google maps. Same for music, podcasts, etc.
I'm not sure if this is actually better on android, but I happen to prefer googles apps much more so it's less of an issue (I think there was a study recently hat way more people, even iOS users, use google apps.)
Is "ok Google" useable by other apps? I haven't found any non Apple ones that hey Siri works in.
I believe these apps are integrated with Google Now(i.e. "Ok, Google").
In fact, here's a very comprehensive list of commands that can be done.
