What service is the Podcast app on my phone connected too?

[Windows Central Question]

I have a Lumia 950 and I have the podcast app. I want more info on this app but I can't find it on the appstore or any info about it. Is there a way to find out. I get some podcast that are on iTunes on it but not all so I'm trying to figure out where are people posting these podcast for it to appear on this app.

In my phone it's just known as Podcast.

Thank you,

And I wasn't connected when I asked this, so yes would like to know if anyone can help.
