The main objective of the app is to create a communication channel between citizens and the Ertzaintza, the Basque police. The app facilitates new means of communication with the police through any mobile device and through various channels such as SMS, email, telephone, or WhatsApp. A very important feature is that the app keeps the anonymity of people (if they wish) to increase collaboration. Another important aspect is that the app works 24 hours, that is, users can communicate with the police whenever they need it. The solution enables citizens to have direct contact with the police agency and provides multiple channels to facilitate communication (i.e. mobile, email, WhatsApp, SMS, and direct contact with the emergency number). In the event that a physical visit is needed, the app also provides a list of all the police headquarters to facilitate a physical visit. In order to maintain a continuous flow of information from the police to citizens, the App provides news, recommendations and links to Ertzaintza's social networks. To mainstream the use of the App, a dissemination campaign was carried out after the App launch. The Basque police used posters to announce the launch of the application.
