This deliverable describes the development process and initial release version of the AURORA app, which will be used by citizens to track their energy behaviour. It is already available on TestFlight (Apple) and will be released to the Appstore after key discussions about some features have been concluded within the consortium (Section 1). The app has been developed using a co-creation approach by involving citizens within each AURORA demo-site from the start (Section 2). Based on the app co-creation report, formulated on those inputs and findings, an app development roadmap was produced to prioritise features of the app based on requirements by the Grant Agreement, discussions within the project consortium, and needs of future app users (Section 3).
