In Los Angeles fire area and it says the air quality is good.

While health officials saying we have to stay inside because it’s so bad 😣

Best air quality app in SoCal

This app needs to be broadcasted IMMEDIATELY across the regions impacted by these horrific fires. It’s the best data source for air quality and air pollution—including custom notifications, forecasting, and detailed breakdowns of each pollutant’s levels. Why are the local agencies not including this in the list of resources for their communities?!

Exceptional, accurate, and up to the minute

Puts other air quality apps to shame. When there is an ongoing fire or smoke situation this is the app!
Uuinazi

Best and most reliable air quality app

I rely on this tremendously daily. Especially now that there are 4 live fires going on around us. This app gives us live update of air quality and e-mail or text alerts when there is known air dust. It also warns you and predicts ahead. It tells you what groups of people may be harmed based on color coded index of air particles and pollution. I am surprised not many people know about this app, and not a lot of reviews. But we live by this app and check it almost hourly sometimes for years!
