If you have an iOS device and love RSS, you’re no doubt already familiar with Reeder, one of the most popular ways to enjoy Google Reader feeds on the iPhone, iPad and iPod touch. After months of being tested in public beta, the Mac OS X version of the app has finally arrived.

Developer Silvio Rizzi released the official Reeder for Mac 1.0 to the Mac App Store overnight at long last, much to the joyful cries of 49 users (and counting) who have given the well-regarded Mac port a solid five-star rating. And with good reason: The iOS version is consistently held up as a model of excellence.

Like the existing versions for the iPhone/iPod touch and iPad, Reeder for Mac syncs with your Google Reader account, offering a beautiful layout with a highly customizable interface and shortcuts galore. But Reeder for Mac isn’t just a pretty face, it really gets down to business when it comes time to organizing and reading your RSS feeds as well.

Reeder for Mac also offers deep Integration with other services, including the paid Readability service, Instapaper, Read It Later, Twitter, Pinboard, Delicious and Zootool as well as emailing links and viewing articles in a clean, text-only mode through the free Readability, Instapaper Mobilizer and Google Mobilizer.

Last but not least, if you’re on a MacBook Pro or use a Magic Trackpad with your desktop Mac, you’ll also love the customizable gestures built into Reeder for Mac.
