I developed a new Android app that collects air quality information online and presents different pollutants concentrations and the overall air cleanliness at the closest station.
This side project has been done fully using the framework Ionic and is available for free on the Google Play Store
The data comes from The World Air Quality Index project . It is a non-profit project started in 2007. Its mission is to promote air pollution awareness for citizens and provide a unified and world-wide air quality information.
