Personally I prefer HACK [1], which is probably the most extensive HN client for iOS. The amount of options for controlling the look of the app means you can influence the reading experience quite a bit, which isn't true for this new app.
My biggest complaint with HACK is search. Instead of a real UI, it uses its own kludgy search syntax to control what to filter. For example, "foo #stories" filters stories only.

Would absolutely love it if the text could be made bigger (both for reading and commenting)!
By the way, this reply was posted using the HackerNows app itself :-)
For example: "AI" or "startups" or "discoveries"
congrats!
