Best Aqi app used Easy to use and usually reliable. Have lived in Shanghai for past year so now check air quality on a daily basis! But suddenly stopped working yesterday?
Still my favourite of the AQI apps I just find the ability to customise which stations I follow and to take an average of their readings pretty handy (I currently live between stations). This app also seems to be more reliable than its competitors. Easily seeing trends in the graphs is just a funky little bonus. The only quibble is that I think the widget is a little ugly, but I can live with that.
Best of the 4 I have tried Simple, basic, accurate, good for the local area as well as when I travel. I only wish one of these companies would develop a forecast capability for the next 12 to 24 hours. Even a color code for the same, worse, or better.
500max Great app. Can choose locations. Handy widget. Unfortunately it maxes out at 500. Need a true reading for those really bad days.
i want info from more cities in less screen size.xxxxxxxxxx i want widget to inform about pollution index and weather forecast.
Room for improvement Accurate data (both US and Chinese readings) but does not include ozone (O3) levels. Ozone pollution is very harmful to ones lungs, especially children and sensitive people.
* added PM2.5 data for 12 monitoring stations in Tianjin.
Keep up to date with the air quality in 15 provinces! There is poisonous smog!
