Plex android app alternatives?

I was wondering if an alternative to the official Plex app exist officially or not. I'm quite tired of the app crashing while I try to watch a movie on the train or when I'm going somewhere where i can't use my laptop. I use plexamp for my music but id ideally like something for movies and such as well. I have read Kodi with a Plex addon is a possibilty but from earlier experience that experience is best enjoyed on a tv screen and not a phone. If any of my fellow Plex users know anything I'd love to know

Thanks
