How to Quickly Check AQI on an iPhone or iPad. Visit Settings app > Maps > Air Quality Index and tap the toggle to turn it on. The handy thing about using Maps to see AQI is that you can use it to check the AQI of any area of the world where the feature is supported.
Is Aqicn credible?
It looks at all available pollutant readings and calculates AQI based on a maximum hazard value of pollutants measured. So it is wrong to say AQICN is more accurate – certainly not as a measurement of health risk. There is no basis for the cutoff points for each band. It will, however, fluctuate more widely.
