The application will be accessible from any modern device, whether from a native app or via web interface. On areas with several measuring stations, AQI heat maps of pollution will be generated. The Android and iOS app will also support portable measuring units. With the portable units, the user will get information at any location he is staying during the day. The application is designed to interpret the data from the available measuring units from the CITI-SENSE project, but it also enables inclusion of data/measurements from any amateur weather station as well as any commercially available air monitoring products (e.g. Netatmo, Cubesensors).
