In college, they were all the secret identity for versions of the Flash. Since then, I’ve expanded to other comic book super heroes.

Pair Droidify with Shizuku (also on IzzyOnDroid) and you’ve got automatic updates.

For media streaming, what mattered most for me was client software. When I first started with Jellyfin, the Roku client wasn’t as feature rich as the Android and web. I stayed with Plex until the Roku Jellyfin clients had what I needed.

If you’re just on Android and the web, you should be fine with Jellyfin. If you’ve got a smart TV with it’s own app store, you may look at what’s there and what features are available.

It’s picked up nearly every feature I had used on Plex within the last year. The developers are doing great.

OpenKeychain is great for keys on Android. It’s FOSS and available on FDroid. +1 for using a self hosted Nextcloud instance to keep things in sync.
