Google+ has updated its iOS app to add more settings for Huddle, an improved notification system for when you are added to others’ circles and the option to tag someone in a post by typing “+” then their name. Also new is the ability to view content from specific circles in your stream; fixes to performance and stability issues; and support for iPod touch and iPad devices.

It is the last of these updates that is most intriguing. The fact that the app did not have support for iPad devices when it was launched is understandable, as the iPad is vastly different from the iPhone. However, it is bizarre that the app was unable to run on iPod touch devices before now. It is good to see that Google has fixed this with the roll out of version 1.0.2.1966 of the app.

It should be said that this is not a major update, as the app does not have full support for the iPad interface yet (when you use the app on the tablet, it appears in either iPhone size or a blurred zoom display). I’m guessing that the next major update to the app will be an iPad-optimized version.

The updates to Huddle might encourage more people to use the group messaging feature of Google+, while the changes to the notification system are certainly an improvement. The ability to view content from specific circles and to tag people in posts are features I’m particularly pleased about being able to use in the app.

You can check out the latest version of the Google+ app on your iPhone, iPod touch or iPad now.
