We.City is a mobile application to change our cities. It is for those who would like to see positive changes around them, but do not have the time, energy or knowledge to implement them on their own. It is an online platform for public networking focused on urban problems, finding solutions, resources and contractors. 

The project is based on 11 principles of an international movement Project for Public Places, which was founded in 1975 to improve cities around the world through the efforts of ordinary people and local communities. 

The application has a set of interfaces, and each of them represents different types of user interactions, that are necessary to implement local initiatives. They correspond to four types of behavior in civic initiatives: initiation, expansion, contraction and realization and four archetypes of group cooperation: crowdcreation, crowdrating, crowdsolving, crowdprocessing.
