Spare the Air Bay Area is the official air quality app for the nine counties that surround San Francisco Bay: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southwestern Solano, and southern Sonoma counties. The app provides Alert Day notifications, county by county air quality forecasts, several tools to help you personally reduce air pollution, as well as air quality podcasts.

•Air Alerts – Provides Alert notifications when the Bay Area is experiencing a Spare the Air Day.
•Local Air Reports – Provides 5-day air quality forecasts for each of the nine Bay Area counties.
•Report a Smoking Vehicle – Makes 1-800-EXHAUST smoking vehicle reports even easier by allowing users to simply text in the license plates of smoking vehicles.
•Bike Route Planner – An active way to spare the air, this tool provides bike route directions and maps.
•Air Quality Podcasts – Contains health and air quality podcasts from the Air District and partners such as Breathe California.

The Spare the Air Program was established by the Bay Area Air Quality Management District to educate people about air pollution and to encourage them to improve air quality by making clean air choices.

Failure to log Yolo fire smoke, failure to alert


Fails to convince. July 1 in SF we’ve had 12 hours of yellow sky, sunless overcast. This is how Pittsburgh PA looked in the 70s - dirty yellow. SFGATE reports “red flag” air pollution. The app still gives a green flag and “NO SPARE THE AIR ALERT”.

Politics aside, it does what it advertises.


I've seen a lot of reviews bashing the spare the air policies. I respect that we all may have differing opinions, but this app does exactly what it promises: you open it and right at the top it says if it's a spare the air day or not.

What else did you expect this thing to do? Sure it claims to have push notifications, but there hasn't been a STA day since I got the app so I can't comment on that. It claims to give the least smoggy bike routes, my experience has it being accurate enough. It lets you report smoking vehicles and see a forecast, but at the end of the day it has only one job: tell me if its an STA day or not!

Now, if you got this app thinking there would be a button to change civic policy or thinking that this app would allow robust and meaningful discussions surrounding a cost benefit analysis of various region wide air quality interventions, then I'm sorry to be the bearer of bad news. This app is to tell you if it's a spare the air day or not. If you want more than that, in all sincerity, please write your senator and convince them to change the policy, not a bad app review to convince people that this app doesn't tell you if it's an STA day or not, because it does.



Was this a competition to see how quickly I could delete your app? You got about 45 seconds on my phone before it was gone. Completely useless.

I am a strong supporter of spare the air days and love the fact that pollution is so closely monitored and limited. With that said, I cannot think of a greater public relations failure than the Bay Area air resources management district. No one has any idea what you do, how you do it, or why. If you took even a small amount of time to actually communicate to the public about what you're doing and what the risks are if not doing it you'd gain massive support. Instead, the district and this app are a joke.
