What I miss on every HN app I tried is a focus on search.
Maybe I'm using HN differently than most people, but I usually look for discussions on topics I'm interested in, instead of reading the top posts on all topics.
For example: I'm an Android developer, so I often browse hacker news by searching for "Android" in topics and comments, to see if there are any interesting discussions.
A great app for my usecase would allow me to search and quickly repeat previous searches right from the startpage.
You could add widgets that jump directly into saved searches.
and when you open it in Chrome-Android use the 'save to homescreen' option so that Chrome adds an icon on your homescreen, which opens the specific page
