Swarm by Foursquare is a new social checkin and meetup up for iPhone. At first I was a little stumped. Why would I need Swarm if my friends and I already use Foursquare? However, as I started using Swarm I started to change my mind. It's a different app and it's useful for something that's both similar and yet very different from Foursquare — seeing what your friends are up to and figuring out how and where to meet up with them.
GetGlue, the popular check-in app for media and entertainment, has been updated with a much improved upon interface, better personalized guides for movies and tv, added video clips and photos for your favorite shows, and more. The update has also added supper for the iPhone 5, so if you've been waiting on that, you'll definitely want to grab the update.
