I think there's room for a podcast app that positions itself as being for the *serious* listener — the ones juggling dozens/100s of shows.
Main things I'd want from it:
— Daily, ongoing, and short-run shows get treated differently in the UI
— Better tools to make playlists
As it is, it's actually pretty hard in most podcast apps to keep track of limited-run 6-ep shows — even ones you really want to listen to! — if you're already subscribing to lots of more frequently updating shows too.
Yeah, Overcast, Pocket Casts, Apple Podcasts, etc all do the playlist thing but the automation pentameters aren’t around show attributes. Hypothetically they could be since shows have category tags and apps like Overcast and Pocket Casts already surface expected release cadence.
