Fans of Google+ will be thrilled to hear that the app has a few upgrades for the iPhone — not to mention an all-new, fully optimized iPad app. With the free Google+ app, you have access to all the standard features of the social network while you're on the go. Not only can you chat with your friends on Messenger straight from your phone, but you can also video chat with up to nine people in mobile Hangouts. Even cooler: you can open the Hangout on your iPad and stream it to your TV using AirPlay technology.From creating and managing Google+ Events on your iPhone to saving cell photos in a private Google+ album, the app helps you sync your content between devices, even if you're not a devoted Apple or Android user. Plus, thanks to vibrant, high-resolution images and a simple look, the app has a clean design that's easy to navigate.
