I'm confused. I used to use and absolutely love Alien Blue. I love gestural swiping. It makes collapsing comments and moving rapidly between posts easy. Reddit bought Alien Blue. Sure, it's got ads and other bullshit, but the core UX is the same. I've never had it crash or cause any problems. I've always been confused by what people mean when they utterly trash on the "official reddit app". Is there another one I'm not aware of?
