You can rate the air quality next to you using four colours:
Green, meaning that the air quality is very good
Yellow, meaning that the air quality is good
Orange, meaning that the air quality is poor
Red, meaning that the air quality is very poor
If you select yellow, orange or red a second window will appear asking you about the origin of the pollution: traffic, industry, house heating…

You can also leave a comment about the air quality next to you.

Other users will be able to see your air quality rates and comments. Some people is very sensitive to air pollution and your information can help them to avoid polluted areas.
