I am KING (Queen?) at avoiding people I know in public places. Duck, dodge, run. Do absolutely whatever it takes to avoid that small talk. Cloak is an app that relies on Instagram and Foursquare data to let you know where all your friends, enemies, and people you feel pretty “meh” about are at all times so you never have to run into them. Think of it as your personalized antisocial network. Exes, annoying neighbors, coworkers, avoid ’em all!
