Local Haze ne fonctionne plus

Local Haze displays the EPA’s Air Quality Index (AQI) and a confidence rating for each sensor reading.  In addition to viewing current air quality conditions, using Local Haze allows you to share sensor maps displaying air quality readings anywhere in the world.  Local Haze reports air quality data from a variety of sensors including: PurpleAir, Sensor.  The confidence rating is a feature that is unique to Local Haze and depends on many factors, including sensor maintenance and data freshness.  Local Haze crowdsources outdoor air quality data from many different sources and delivers it to your iPhone.  Local Haze displays the level of smaller PM 2. 5 particles, which pose the most significant risk to health.  Environmental Protection Agency (EPA) have developed guidelines for safe air quality as impacted by chemical pollutants and particulate matter (PM). 

PM smaller than 10 micrometers poses problems because it can enter the bloodstream.  Now you can subscribe to receive a notification when there is a significant change in the air quality readings for sensors by PurpleAir, Sensor.  Red badge with thumbs down: Low confidence in the air sensor reading.  Green badge with thumbs up: High confidence in the air sensor reading.  Yellow badge with OK sign: OK confidence in the air sensor reading.  Notifications: New subscription feature in version 2. 1 of Local Haze!  We hope you enjoy using Local Haze!  The general public is not likely to be affected, but persons with heart & lung disease, older adults and children, are 
at greater risk from the presence of ozone or particles.  Air quality is considered satisfactory, and air pollution poses little or no risk.  Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
