These days, HN is one of the rare things I don't consume using RSS. I installed and liked it instantly. I have been using Materialistic for as long as I can remember trying out HN clients. The only feature I wish it had is being able to collapse a comment tree without collapsing the root comment of the tree. Would make it easier to read comments in a BFS fashion.
I'd also like to point out:
> The developer says that this app doesn't collect or share any user data.
That's what ultimately prompted me to try it out.
Very good job OP.
