Mobile Apps



Try the CityAir App

CityAir App is developed by NILU. With CityAir App, you can report the air quality of your area to us. The app allows you to rate the air quality in your area: green if the air quality is very good, yellow if it is good, orange if it is poor and red if the air quality is very poor. You can also indicate the source of the pollution (i.e., traffic, wood burning, industry, etc.) and leave a comment.

Your contributions will help to create a citizens’ air quality map. Other users will be able to see your air quality ratings 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 get CityAir app on Google Play Store and Apple App Store.
