I'm currently building an audiobook app. I've considered adding podcast (and even music) support, but wonder if this is something people actually want bundled together or would prefer tailored experiences.
It's still really early and I'm currently using some AGPL libraries which means I can't distribute without also being AGPL. I haven't been able to find a good way to make money on an app while releasing it open source. Would love to figure out a way to do both.
