What is CityAir app?

Air pollution is invisible but it affects people’s health. 

With the CityAir app you can help to colour the air pollution by rating the air quality where you are: green if air quality is very good, yellow if air quality is good, orange is air quality is poor and red if air quality is very poor. You can also indicate the source of the pollution (i.e. traffic, wood burning, industry, etc.) and write a comment.

Your contributions will help to create a citizens air quality map. Other users will be able to see your air quality rates and comments in real-time. Some people are very sensitive to air pollution and your information can help them to avoid polluted areas.

You can download the app either for your Android or iOs



How to use the app?


Below we give a short walkthrough of the various screens and functionality in the CityAir app. 

Screen 1: The first screen is always a popup screen with input fields for the user. The user can chose to stop this popup for being displayed every time, by checking the "Hide start popup" box.

Screen 2: This is the seconds screen (or the first if the user chose to hide the popup). It contains all perceptions and comments the user has reported. The markers are clickable and will display the comment or the pollution source.
Screen 3: On the bottom of the screen, there are four buttons. The man is the report option. When clicked the user can choose between adding a colored marked man according to the Air Quality perception, or leave a comment.
