Google Calendar is out with an improved version for the iPhone today with version 1.1. The list of changes is short but the improvements should be welcome.

The update includes integration with Google Drive so users can connect files with events on your calendar. Interactive notifications now include the ability to open directions from alerts or respond to guests via email.

Google Calendar for iPhone is available for free on the App Store. Version 1.1 follows the initial launch in mid-March. Full release notes below: Read more of this post
