If you own an iPad, you’re probably already familiar with Flipboard. It’s like an RSS reader, but the app aggregates content from social-media sites—Facebook, Twitter and Instagram, et al—as well. Even better, you can choose from other sites from which to pull content—whether its news content from The New York Times, art from Juxtapoz Magazine or photos from your favorite food blog. Essentially, it’s a personalized magazine you can flip through on your iPad or smartphone. The application, which first debuted exclusively on iPad, is now available for iPhones and Android-based smartphones. www.flipboard.com.
