Nice work! Seems consistant with the SN feel in web browsers. My only observation is that spacing of articles heading and link seems a bit too much space. If there is a way to keep that a bit tighter, that would really help maximize the app's utility and aesthetics.

I guess it's a hard task with limited screen affordance on various devices. I'm looking at it on iphone 7 and readibility is fine, but quite a lot of scrolling. I'm not a UX designer and don't know if it's even possible to get 21 articles to seem a little more snuggly formatted.

Maybe if it was possible to abbreviate the link to just display the tld without breaking to a new line you might fit in a few more elements for sat tips. Just my 2sats!
