Google Came up with their brand new App "INBOX"

INBOX

Yesterday Google's Gmail team launched a brand new App called, "INBOX".They have mentioned it in their blog http://googleblog.blogspot.in. The basic idea is this: it's still a Gmail app, but instead of giving you the traditional list of emails, it tries to intelligently give you more information so you don't have to even open them. Google Now-style info cards appear right in line with your message list, including things like flight times, package tracking, and photos.
  "It follows invite system" where you need to get the invitation to start using this. 

Inbox is total reinvention of gmail from google

 This application is developed by the same team who brought Gmail to us.The email started simply as a way to send digital notes around the office. But fast-forward 30 years and with just the phone in your pocket, you can use email to contact virtually anyone in the world…from your best friend to the owner of that bagel shop you discovered last week.
With this evolution comes new challenges: we get more email now than ever, important information is buried inside messages, and our most important tasks can slip through the cracks—especially when we’re working on our phones. For many of us, dealing with email has become a daily chore that distracts from what we really need to do—rather than helping us get those things done
Following is the video how does this "INBOX" works for you.
Following are some of the features of INBOX:

Bundles: stay organized automatically

Inbox expands upon the categories whichi is already introduced in Gmail last year, making it easy to deal with similar types of mail all at once. For example, all our purchase receipts or bank statements are neatly grouped together so that we can quickly review and then swipe them out of the way. we can even teach Inbox to adapt to the way we work by choosing which emails we'd like to see grouped together.

Highlights: the important info at a glance

Inbox highlights the key information from important messages, such as flight itineraries, event information, and photos and documents emailed to you by friends and family. Inbox will even display useful information from the web that wasn’t in the original email, such as the real-time status of your flights and package deliveries. Highlights and Bundles work together to give you just the information you need at a glance.
