Google+ Collections come to iPhone, allows you to group posts by topic

If you're an avid Google+ user on your iPhone, you'll be happy to know that the app has been further brought up to parity with its Android counterpart with Collections. The feature allows you to easily group posts by topic, much like a similar feature in Pinterest for those who are familiar with the service.

Collections essentially help cut down on the noise, allowing users to browse by specific things they are interested in. You'll be able to customize each collection with a color and header image of your choice, and set them to be private or public so others can follow along.

Collections have already been live on the web since May, so frequent Google+ users who are taking advantage of them should see them carry over on their iPhone with the latest update.
