Smog Alert funktioniert nicht

Air quality data is not modified by the Smog Alert system – it is displayed in source form.  With Smog Alert, you can check the current air quality index in many locations around the world.  Smog Alert doesn't measure the level of air pollution – your smartphone doesn't have any sensor that can measure the level of smog.  The application focuses on local action, retrieving information from more than 3,000 air quality testing stations in both large cities and smaller towns.  Smog Alert – all the most important information about air quality in one place! Not enough?  Daily air quality alerts in your area will help you to do this.  Breathe consciously.  See what kind of air you breathe every day!
