Developing and testing of a mobile application to support research activities is one of the goals of the C3Places Project. The C3Places application is designed to enable researchers to address questions related to the use of public spaces via digital technology. A relevant aspect of the digital and mobile technologies lies in their possibility to enhance communication with prospective users, hence enabling possibilities for creative participation in placemaking and co-creation.

The C3Places application consists of two main components: a web service (web platform) and the smartphone application (app) and is enabled to be used anywhere in the world.It allows researchers to collect evidence base and demonstrate the social values of public spaces – backed by users’ opinion and views. Also, by providing evidence and demonstrating that public space is having a positive societal impact can increase the enthusiasm for more inclusive and responsive public spaces.

By collecting such data, the C3Places App contributes to better explore and more precisely research on public space practices, as well integrate the use and point of view of several users on different spaces. Another interesting feature lies in the possibility to collect the weather conditions automatically, therefore researchers can also reflect on how weather conditions affect (or not) the usage of public open spaces.

Finally, considering that it is up to the researcher to create the questions or the photo questionnaire, the possibilities are infinite and can be addressed directly to each research topic that is being carried out. So, the C3Places app allows scholars and researchers to make more specific or broader public open space research and, since it runs in Android operative system, the range is quite extensive. The use of the C3Places App is free and can be requested at
