Google released an iPhone update for Google+ back in May, and it seems the folks at Mountain View have been busy brewing a separate app for the iPad.
The new Google+ app for the iPad takes advantage of the additional real estate on the iPad and lets you drag posts from your stream for sharing, as well as allowing for comments to be added to posts by just pinching and expanding them. The new app also works with AirPlay and lets you stream Hangouts from your iPad to your TV with it. Meanwhile, the iPhone app gets a minor improvement; users can now create and manage Google Events from their iPhone.
