There are plenty of RSS readers for iOS, but one of the most beloved is Reeder, available in versions optimized for the iPhone/iPod touch as well as the iPad. Now the developer is taking on the Mac with a slick new beta.

TechCrunch is reporting that Reeder for Mac is now available from developer Silvio Rizzi, following up the success of the same app for the iPhone/iPod touch and iPad. For now, Reeder for Mac is a free public beta (designated as “Reeder 1.0 Draft 1”) that’s missing a few features, but the stylish app appears to lose very little in the transition from iOS to the Mac. If you’re not familiar with Reeder, it’s an RSS feed reader that syncs with Google Reader.

The user interface shown above will be familiar to anyone using the iOS versions of Reeder, grouping your Google Reader feeds in a thin pane at the left. When clicked, you’ll see a list of the included feeds in the center, and selecting one opens the larger pane on the right side for reading.

Among the features missing from the first beta release are feed management (which can be done at the Google Reader website anyway), search and a downloads panel, all of which developer Rizzi claims are coming soon.

Meanwhile, Reeder for the iPhone was updated to version 2.2 on Tuesday night, bringing two welcome changes. The first is the ability to share articles on Facebook, which has been long overdue. Also new to this version is the ability to change a preference setting to allow a swipe to the left to quickly add the article in question to either Instapaper or ReadItLater.

You can try out Reeder for Mac right now by downloading it from the developer’s website. Rizzi is targeting the release for the forthcoming Mac App Store, but says there’s no version planned for Windows -- sorry, Microsoft fans.
