This short document is intended to be distributed with the wireframes and prototype of the DECODE APP v2.0. Those wireframes are the basis upon which the second version of the DECODE App (link to store and repository) is being developed. The wireframes design is intended not only to integrate with BCNNow, but with all the pilots considered in Barcelona (and described in the work package 5 deliverables). The document is structured in two parts. The first part places into context the previous research performed in the project and introduces the main results of the research done to design the app. The second part presents the design decisions and philosophy behind the prototypes that are presented as well as the wireframes that will be used by the app.
