Hacker News Pro is a clean, fast app for reading articles from Y Combinator's Hacker News. It uses Instapaper to provide an optimal mobile reading experience, and also offers access to the original article's web page.
Hacker News Pro easily integrates with your Twitter, Facebook, and Instapaper accounts to let you save and share your favorite articles. It can also send article links and entire articles via email.
Future improvements include the ability to view and add comments, as well as vote on articles and comments.
