Google has made a new version of Google+ available to iOS devices, such as the Apple iPhone. Many of the new features are carried over from the recently-revised Android version of the Google+ app.
Google+ 4.4.0 for iOS includes a number of improvements to the photos portion of the service. It offers a new auto-enhance tool for improving uploaded images. Google+ will assemble collections of photo highlights and the app is now better at sharing GIFs and panoramas. It is easier to find content through the use of hashtags, and Google+ now lets users adjust more facets of their profile from within the app. Google+ adds support for strikethrough text and the ability to edit comments.
Last, the Hangouts feature is no longer available within the app (Hangouts is available separately). Google+ 4.4.0 for iOS is a free download from the iTunes App Store.
