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.

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 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.
