BlockChalk Introduces Super Simple Location Based Annotation of Real World
You're stuck in a stall with a clever response to that scribble on the wall, only problem, you're a Sharpie short. With BlockChalk, mobile users can now mark up and annotate the real world through a digital space. How does it work? By tagging text comments with coordinates, they are fixed to a physical location and pulled up only when others are in the same space. Think geo-tagged tweets or Foursquare and Loopt tips, which when put together become one piece in the larger trend towards hyperlocal content. The app is available for iPhone, Android, and webOS making the likelihood of stumbling across a friend's digital trail of witty remarks and complaints all the more likely.
