Qwilio
Qwilio is a platform that lets anyone create and view focused, location-based guides for smartphones. Qwilio's micro-guides are precise windows into corners of local knowledge, such as: a walking tour of a neighborhood, a list of the best coffee shops, or a guide to a visiting art exhibit. Qwilio guides can be searched and viewed from the web app or from a variety of mobile devices.
