Many Disappointed Users ,

Bring web features to mobile app

The service is fantastic so this rating is for the company and the service it provides so that I can have peace of mind and know when it is safe to open my windows and let fresh air in. The mobile app is a bit cluttered and not intuitive. I also would like to see the mobile app have the same (or better) functionality than the mobile website. Specifically, on the mobile website I can see a map of my neighborhood and it is layered with dynamic points of interest, fires, wind patterns, and a heatmap. None of this is available on the mobile app, so to get this functionality I have to keep the mobile website open and come back to it, rendering the app a lot less useful. I would also make it easier to find the nearest air quality station by allowing the user to enter an address and have the search results show nearby air quality stations so that the user can select the station they prefer to monitor in the My Air section of the app. The AirVisual Earth feature is fantastic, very evocative: it is beautiful and compelling and disheartening at the same time to be able to see air quality around the world. Thank you AirVisual team for putting this tech and service out to the world for consumption, awareness, and perhaps even reflection.

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.

Your AQI in an app

This free app can help you with information and forecasting of the air quality in your area. Since the 1970’s I’ve been personally interested in my home environment mainly because 3 of my family members, my husband & 2 children have hay fever in the Spring. We installed an electronic air filter in our furnace and air conditioning system which seemed to help immensely.

Fat forward another 30+ years when we discovered the AirVisual app & their small device that could monitor our indoor air quality. Yes, using an AirVisual device is an easy way to monitor and improve your own air quality in your home. I discovered that NOT opening the windows to bring in a little fresh air was bad for us. Our carbon dioxide CO2 levels were getting in a higher range and causing headaches and lethargic behaviors. Being retired and at home most of the time, this became even more important to monitor our indoor AQI. Thank you AirVisual for providing the tools and information for a healthier lifestyle. 🥰
