You really have no reason to think about air quality unless it's a problem. And when there is a problem, it's a problem . I live in northern California and the tragic Camp Fire has created incredibly uncomfortable, if not insecure conditions throughout the area. Schools have closed in response to the horrendous outdoor air quality in recent days, usually in the "Unhealthy / Very Unhealthy / Hazardous" area of the official air quality index.
I had checked websites like AirNow on a regular basis, but it's getting a bit boring and depressing when you see regular photos like the one on the right. (Red means that the air quality is pretty bad, purple means it's very bad.)
Fortunately, software engineer Gabriel Lewis wrote a small app a few days ago that drops the air quality index directly into the Mac menu bar. All you need to do is to provide a zip code and the app is just called " Air " ̵
When I write this, it's slowly starting to rain where I live in Northern California, which means that the air has been much better since yesterday, and the Air App's notice has become green. My lungs hope it stays for a few days, at least.
