LinkedIn's Connected app is a new standalone one that's designed as a replacement to static contact lists. Instead of providing you only a name and a number, the app makes your network seem far more personal. With Connected, users can keep on top of when your contacts get new jobs and have birthdays, so that you can properly congratulate them.
On top of this, one really handy feature of the app is that it rounds up information for you, which is extremely useful if you have a call or a meeting with someone and need a quick refresher. Connected provides a summary of things like when you and a person first connected, your shared contacts, where you met and key pointers to remember, including things like their interests and notes about their family.
