Google has updated their Google+ app for iOS with a completely revamped design, similar to the recent design changes at the Google+ website. Some of the changes include new fonts, larger profile pictures, and full-screen display mode for photos.
From the Official Google Blog:
To be clear, we’re not interested in a mobile or social experience that’s just smaller. We’re embracing the sensor-rich smartphone (with its touchable screen and high-density display), and transforming Google+ into something more intimate, and more expressive. Today’s new iPhone app is an important step in this direction—toward a simpler, more beautiful Google.
Interestingly, Google still has yet to update the Google+ app for Android, although an updated Android version of the app will be released soon.
The updated app is available for free from the App Store (free, App Store link), and the full release notes can be found at the Google Blog.
