Google+ for iOS gets updated, adds new photo features3
Google will also now include related hashtag support. This means that your pictures might automatically include some hashtags on them. The update also pushes Hangouts to its own app for messaging and video calls, gives you control over the number of times What's Hot appears on your stream, and allows you more control over profile fields while letting you upload a cover picture. You can even display strikethrough text if the feeling moves you.
Google+ for iOS requires that your device be running iOS 6 or later, and is a free download from the Apple App Store.
