The Utah Air application employs Utah Division of Air Quality's new air quality alert system that consists of action alerts, represented by three basic symbols that signify the voluntary or mandatory actions (e.g., carpooling, wood burning) the public needs to adhere to the current pollution levels, and health guidance, based on the EPA’s Air Quality Index (AQI) that helps determine how the highest pollution level of the day will affect people with various health conditions.

Utah residents can check into the app daily to know when not to use wood and coal burning stoves or fireplaces, the best times to exercise outdoors, or make one consolidated trip for errands based on current conditions and trends. The three-day forecast can help individuals plan ahead to adjust their travel plans or work schedule to avoid adding harmful emissions during winter inversions or during the summer Ozone season.

Great app but please update/fix

5 stars for great app that I use all the time. I’m keeping an old iPad just for this app. It appears to no longer works on the newer iOS devices. That is why I think it starting crashing every time I try to open it on my iPhone 7 but worked fine on earlier iPhone models. PLEASE update this app to work on newer iOS devices or fix whatever bug is shutting it down immediately on the newer devices.


Great Upgrade

I really like the new interface. It’s more streamlined and looks more modern. The info we need is right there, easy to find. I’ve used this app for a number of years. The information is great, but it’s not always been stable. It’s also often been hampered by air monitoring stations that go offline. Hopefully the new version will be stable, and hopefully the stations will remain active. Thanks for providing this.


Handy if a little clunky...

Glad it's available and working again. Not liking the request to use location even when app not open.

Why no stations in Provo?

Old version was crashing on launch for me from June-December 2017). Also had non-standard navigation elements and charts sometimes were extremely distorted.
