'Breakup Notifier' App Keeps Tabs on Unavailable Friends New app will alert you when your beloved becomes single By Evann Gastaldo, Newser Staff Posted Feb 21, 2011 9:51 AM CST 3 comments Comments A screen shot from the "Breakup Notifier" site. (breakupnotifier.com) (Newser) – It's tough to keep tabs on all those Facebook friends—who has the time to constantly check the status of a bunch of currently-taken potential lovers, waiting to pounce as soon as you notice that “In a Relationship” has changed to “Single”? Well, thanks to programmer Dan Loewenherz, you no longer need to keep tabs on them … his new app will do it for you. “Breakup Notifier” allows you to select your “taken” friends, and receive an email when any of those friends changes their relationship status. Which in turn frees you up "for stuff like standing outside peoples' windows, and stealing bits of their hair for your special doll,” Gawker notes.
