Mine's definitely a labor of love - I use it daily, and hardly ever use the browser version unless I want to comment on something. I'm working on adding commenting/submitting/voting at the moment, and should have that done shortly. Personally, I think it's the most beautiful HN reader on the App Store, but I may be biased. It's free too.
Thanks for your contribution, I'm glad you love it! I can't wait to get user management type stuff on there so I never have to open the browser version again.
Thank you so much for your reader AND especially for open sourcing your code (which I just found out from your comment).
I use yours everyday and have occasionally found issues. Now with the code available, expect some pull requests :)
