Kommon

Ever meet someone and want to know right away who you know in common? Kommon will improve the way we connect with people we meet by telling you mutual friends on the spot while adding their info to your address book. After putting in the contact info of someone you meet, Kommon automatically adds them to your address book, and records the date, time, and location. It simultaneously looks up who you know in common on Facebook, LinkedIn, and Twitter, allows you to friend/connect/follow them, and add notes to the address book.
