What happens when you make a Google Reader client for iPad and Mac, and then Google announces that the service is closing up shop on July 1, 2013? If you're developer Silvio Rizzi, you continue development on a version of your app that won't rely on Google Reader, and you give away your app for free. As of today, Rizzi is making Reeder for iPad and Reeder for Mac freely available.
In an announcement made this morning, Rizzi noted that "it's still too early to have answers to all questions I got over the last few weeks." He noted that development of Reeder will continue on all platforms, and that the iPhone version of the app already has support for services other than Google Reader. Version 3.1 of Reeder for iPhone will be available soon, and Rizzi says that "the plan is to add more services you can choose from in the next weeks and months."
For the Mac and iPad versions, version 2.0 is in development and will be available "in the coming months." It's expected that version 2.0 of Reeder for iPad and Reeder for Mac will add the features currently seen in the iPhone version, which includes all sharing and syncing services. In the meantime, the iPad and Mac flavors of Reeder are free.
