I was in the same boat before COVID. Podcastmarks is mobile friendly which should allow you to listen to the podcasts while driving. I do have app options in the works.
Biggest issue I saw with using Podcastmarks while driving would be the bookmarking and potentially adding notes. I would need to explore more voice control options as I move forward. That is an area I am not sure about in regards to building the app and using it while driving.
But, I appreciate the feedback! I definitely will add your ideas to the growing list of suggestions to help triage development efforts. It does appear I need to make it more apparent there is a mobile ready option currently available.
In the meantime feel free to check out Podcastmarks and let me know what you think!
