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.

PopcornTime (download the tv version).

Saikou for Anime. It can be a bit of a faff getting logged in, but it’s worth it.

Streamio + Torrentio

JellyFin is a great media streaming app (fork of Plex), and has an android TV app. Also for anime there’s aniyomi.
