Yes. Kodi is awesome for large displays, but I really don’t think the UI and skins are a good fit for mobile.
I’ve tried DDL for a while, but manually searching and selecting the right quality isn’t my thing. It’s simple though, compared to the many hours of setting up arr* for the right quality/language.
The main advantage is probably automatic download of new episodes, otherwise manually downloading doesn’t take much time compared to how long a movie/show is.
