(Mashable) -- Update: Google has already released an update to the Google+ app. For those that are having problems, check the App Store and download the latest version.
The official Google+ iPhone app is now available. The app is available as a free download [iTunes link] from the App Store.
Here's a list of the app's features, along with their descriptions.
-- Circles let you share the right things with just the right people.
-- Stream is where you can get updates from your circles or see what people are saying about things nearby.
-- Huddle is super-fast group messaging for everyone in your circles.
Buggy, but fun
First impressions of the app are that while useful, it's buggy. The app doesn't work on iOS 5 beta 3 -- so cutting-edge adopters, you're out of luck (for now) -- and is crashing in iOS 4 at regular occurrences for some users.
Punit Soni, lead product manager for Google+ Mobile responded to some of the complaints on Google+ and he is promising updates.

Comment: it's good having know an google app becuse sometimes in iPhone and in iPad it was like stocked on the different ways you can use google apps. I mean in a computer there are many function usable just entering google.com, but know it will be easier on apple dives, just taping on your app you will enter on a google world, just for free.
