POPUP

PopUp is like Twitter for places - With the PopUp App, you follow people and brands and their messages are delivered to you not on a timeline, but automatically to your phone, at physical locations as you move through your day. Only the most relevant info about where you are, from the friends and brands you trust, is delivered to you. And you can then create popups, too, and leave them for your friends and followers for them to discover. The PopUp App and APIs allows anyone - a person, a brand, an advertiser, a content publisher - to create content that is delivered to their audience at a specified location.
