Stremio is pretty good. There's a list of all the addons in it so you can install whichever addon you want with one click easily. A lot of them are torrent addons like TPB or RARBG which are basically torrents. You can choose a source which has a good seeders and stream movies within the app itself. I have used stremio for a week or two before uninstalling it because I wanted to focus on studies. This is all I know and I can say about stremio. Feel free to correct me if I said something wrong.

Edit: I have used Kodi as well. I like kodi but it is a bit annoying because you have to do a lot of tweakng
