If you're not really that satisfied with your built-in phonebook or your current contacts app and if a lot of your contacts are on LinkedIn, then this new app is something you can consider being a replacement for the current one you're using. LinkedIn Connected brings more than just the usual functionality of a phonebook and integrates information that your contacts have added to their LinkedIn profile to help you build a better relationship with those you'll be encountering both online and offline.
Connected lets you know the usual birthdays, anniversaries, milestones that it will be able to get from their LinkedIn profiles and their existing info on your smartphone, as soon as you sync your contact and calendar with the app. It uses a card interface so that it is easier to look at your contacts, just like you would a business card. You can also get a deeper insight into a colleague that you will be meeting up with, like their interests or their last activities, so that it would be easier for you to connect with them once you're face to face.
If you've made an entry on your calendar that you're meeting up with one of your contacts, it can give you notifications once you're in that meeting already, giving you a "secret weapon" with which to break the ice with. And you don't need to actually open the app to view information, since it has a widget where you can view details from your smartphone or tablet's homescreen.
You can download LinkedIn's Connected app for free from the Google Play Store. The main app for the professional social network is still there, but it is used more for the actual networking, and this new one is more for connecting with your existing contacts already.
