App Description
Hazel tells you how bad the haze is right now, right where you are.
Make better decisions about whether you need a mask, or if you should be bringing your baby out.
Hazel calculates the 1-hour PSI using a formula provided by NEA. It converts the concentration of PM2.5 pollutant into a scale from 0–500.
Hourly push notifications keeps you up to date about the latest 1-hour PSI readings the moment NEA releases the data.
