If you're on Android, you could check out Newpipe or Grayjay.

Just posted this in another thread, it's not implemented yet but TubeArchivist has a podcast mode on their roadmap: https://github.com/tubearchivist/tubearchivist
Ditch the Roku and get another Shield or other Android TV device.
Filebot, I like and use the app but it shouldn't be a subscription. You can buy a lifetime license for $48 but it's too expensive for what it is.
First off I'd recommend investing in Real-Debrid, it's a service that caches torrents for streaming and costs about $3 per month. It's required for most of these apps, or at least highly recommended.
Streamio + Torrentio has already been mentioned, Syncler is really good and easy to use, many extra features with Syncler+ but it's not required.
Kodi with addons works really well, but requires some tinkering to get started and basic maintenance / troubleshooting if something goes wrong. Check out old.reddit.com/r/addons4kodi some good addons are Fen, Seren and Umbrella but there are many others, Otaku is good for anime.
I'd speak to management and voice your concerns regarding the app, and ask if there is another method available for entry. If not, I'd cancel my membership and look for another gym that respects my privacy.
