Brewster is a great app for iOS (Android is coming!) that merges everyone's social media profiles, contact information and more into one place. Once you download the app to your phone, you simply select which accounts you want to link to and then the app's cool technology does the rest.

(If you have a lot of contacts, this download process can take a little bit of time. Be patient.) 

A cool graphic interface organizes contacts by how often you are in touch with them, which is super helpful if you think about it. It also creates lists of people you are in most constant contact with, and even provides updates on job changes, birthdays, recent moves and more. Plus you can receive friendly reminders to reach out to people you haven't spoken with in a while--if that won't make you feel guilty. (Sorry, Aunt Joan.)

The current services the apps covers are Twitter, LinkedIn, Facebook, Gmail, Foursquare and iPhone contacts. So pretty comprehensive. I love that. -Jeana
