Unfortunately it looks like they are only listing partners app from big brands.Podcast Addict will keep playing until another app asks for audio focus. Depending on the audio focus request type it will then automatically resume or not when retrieving focus.
Please send me an email at (podcastaddict@gmail.com) so we can discuss this more easily.
Thanks

This integration "almost" works.
I can start listening to a podcast and then start a workout in Runtastic. And it goes smoothly most of the time unless it doesn’t (sometimes Runtastic cannot resume the podcast after its voice coach pauses it).
Also, as you can see on the screenshot, Podcast Addict is not there on the list of players to choose from.
