PAD Software has introduced SimpleRSS 1.0, an RSS feed reader application for Mac OS X 10.7 (“Lion”). It costs US$0.99 and is available at the Mac App Store in the Lifestyle category.

SimpleRSS features full screen mode support, scrollbars, and more. With its built-in web browser, users can choose to prioritize certain RSS feeds or to have them appear only when there’s a new article.

SimpleRSS is 64-bit and uses a distraction-free sidebar to manage article. It uses a built-in web browser so there’s no need to leave the app to read the articles in another app.
