In this post I want to tell you about a really innovative app that I've found.
The name of this app is "How polluted is the air?": I think that its name is self-explanatory.
"How polluted is the air?" is a free application that lets you know the amount of air pollution by simply taking a picture.
How does it work?
When you take a photo of a place, you send automatically your position and current time with your picture to a system which is located in California. It matches your photo to an algorithm and it sends you a message with all the information about the pollution in the air.
