### 5/5 — AirNow provides critical air quality information

*2026-06-26*

After not working for a while last year, this app is updating again and providing critical information. I check it multiple times a day because I have asthma. It’s the only app I’ve found that provides actual measurements of ozone and PM10, rather than relying on modeled estimates, which can be less accurate than direct measurements.

Your experience with the app will likely depend on your state’s own air quality reporting, since AirNow draws on data from state monitoring networks.

Please keep this app updated!!!

### 2/5 — Missing arrow

*2026-05-30, version 4.6.0*

The last update removed the arrow on the meter.

### 2/5 — Want a widget and better pollutant breakdown

*2026-04-27, version 4.5.0*

I would love a widget like what IQAir has, where you can see current and forecasted air quality at a glance. Also, I’d like to see a ppm breakdown for individual pollutants in addition to the bundled AQI.

### 1/5 — Barely updates in real time anymore

*2025-12-31, version 4.4.0*

Not worth checking, the information is not as real time and loading issues have been really persistent the past few months in particular. Don’t recommend for real time updates

### 1/5 — Not working!

*2025-12-17, version 4.4.0*

What’s up? Why is the app not working? I redownloaded the app it won’t take any locations!

### 2/5 — Eli

*2025-12-14, version 4.4.0*

Suddenly app became totally unresponsive and useless.

### 3/5 — Mid

*2025-11-18, version 4.3.1*

Great when it works

### 1/5 — ""An error occurred

*2025-10-10, version 4.3.1*

Cannot read property 'reportingArea'

### 5/5 — Great air quality monitor

*2025-10-07*

This is one of those apps that I use every day. I check it every morning before exercising to see what the air quality is. They seem to continually update the app and make it better in time.
I don’t have any complaints about the app and find it very useful and reliable

### 1/5 — No Longer Accurate

*2025-09-29, version 4.3.0*

The current US administration does not believe in science, healthcare, climate issues or accurate reporting of any data. So unfortunately this application no longer works. Seek alternative information from your local weather stations outside of the “fox” branding if you want accurate details on the forecast. Most are going to a triangular approach. This means they are taking data from 3 points, taking the average and using it as the hourly AQI. It’s the best we now have unfortunately.
