The app looks great, though have a few comments:

* It doesn't feel like HackersNews. I think you should follow some of the elements from the web app (Orange colour, HN logo etc)

* I wasn't comfortable providing login credentials. How are you handling login / storing my details?

* I'd like to see more posts per page. Feels harder to scan read the posts than on the current HN site

* Filter in top right looks like a location / near me icon. Didn't expect it to display filter options

* How do I see my profile? I'm logged in, but no indication that I am

* Having to click on comments to see 'no comments' feels odd

* The number of upvotes / comments per post is important, feels very buried (couldn't find upvotes)
