This past May, Google revamped Google+ for the iPhone by adding full bleed photos and new visual elements. Now Google+ for the iPhone and iPad has several new features listed below:
You can now create and manage events on Google+ through the iPhone. This includes the ability to post a comment, upload photos, etc. You can also start a video chat Hangout from anywhere using your iPhone and iPad. Make sure to have your ringing notifications on so your friends know how to join the Hangout.
To start a Hangout from the main menu, add a few friends and tap “Start.” The app can ring their phones and if someone misses the Hangout, they can ring you back with a single tap.
You can download Google+ from the App Store (version 3.0).
