Did my research, get it


I have lived in China for 3 years and have a two-year old boy. Once he was born I became more interested in what all the AQI apps actually did and started researching them. AirVisual is by far the best one I have come across (having used 10+ different apps). Not only can you choose to use the US index (which I would highly recommend) you also can see which pollutants are contaminating the atmosphere at any given time. I also have a laser egg (also highly recommended) which is a portable particulate counter and the readings on my mobile device and the closest monitoring station on the app are always within +/-20 meaning they are not contradicting each other. On other apps there would often times be a 50 point+ difference between what my particulate counter read and the other random apps I was using. Also, do note that some apps do, like airvisual, have the different pollutants listed and their levels but airvisual is the only app I have found that combines that with the ability to choose the US AQI standard. My go-to app when it comes to air pollution.

Horribly inaccurate.

Galia Stauffer

I live in South Korea and have for a total of 5 years, spread out over the last decade in a 3 year stay and now 2 years into a 5 year stay, in that time the air quality here has gotten much much worse. I was recently diagnosed with asthma (something that is apparently becoming more common for people in Seoul) and have to check the air quality regularly. If it's above 100 aqi I have to wear a special filter mask to leave the house. I got this app to make it easier to check the AQI regularly, one of the big draws for this app is it notifies me if the AQI goes above 100, or it's supposed to. Yesterday it never dropped below 100 and I never got a notification (thankfully I'd had the thought to check online before leaving the house) and upon checking the app it said an AQI of 63 when it was really 163. If you're relying on this app for all your AQI information and live in a city with poor air quality such as Seoul you may be putting your health at risk by relying on this app.

uncomfortable UI and sightly more cautious air rating


This app is useful because it has daily notifications and a widget. I use this app to check the air quality in Korea. But the number that this app reports is almost always higher than the Naver number, which is probably most correct in Korea. If it’s :( unhealthy on AirVisual, it’s just :/ not good on Naver. or if it’s :/ not good on AirVisual, it’s :| ok on Naver. It can be good to be cautious though!

The worst part about this app is the UI. Swiping from the left never works to go back to the previous screen so I have to move my hand and push the back button in the top left corner. So annoying! There are a lot of menus on the bottom that I never click on like a map, a world ranking, and other not-that-useful stuff. Overall, it’s not that nice to look at and a bit frustrating to navigate. So I give 3 stars.

Developer Response

Thank you so much for giving us a detailed and constructive feedback!
1- AirVisual reports the US AQI standard which indeed differs from the Korean AQI standard. The Korean AQI standard is less strict and therefore indicates "better" value than the American standard.
2- For swiping from the left, it will be in the next version!
3- The menus on the bottom are there to bring context to the data: the map shows what's going on around, the ranking gives an idea of how a city fits compared to other key cities, the articles are there to bring an in-depth view and understanding about the pollution problem.
