Unlike other free movie sites, Viki has a clean, professional look and feels https://pokiapp.com/movie-hd-for-android/ like a premium service. It has a good variety of movies and TV shows, but it lacks a few features we would prefer to see in free movie streaming websites.
One of the downsides is that it limits the picture quality to 720p, which isn't as high as many other HD free streaming websites. It's not a problem if you're using a 720p screen, but it may disappoint you if you are looking for Full HD movies and TV shows.
