Just in time for the sniffly season, the app analyzes your FB friends to determine which ones you should avoid for the Flu season. The app scans a combination of check-ins, and keywords (coughing, sneezing, sick) in their status updates to determine which of your friends are prime suspects. Those suspicious of their friends can then quarantine them, sending a good-natured message that they will be withholding their in-person company until the sickness subsides.
