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.

Current AQ features great, but forecast is a joke

The Good:
Air Visual lets you set a local AQ station as default, and on launch, displays current AQI reading plus 48hrs of detailed history and a week of daily averages. At the bottom of the page, there is a map that lets you scan AQ readings at stations within a ~15mile radius. To get this AQ map, or any local AQ info, on Weather Underground website requires a half dozen clicks to toggle on PM2.5 filter, and WU does not offer any AQ history data, so this functionality makes AirVisual well worth the download.
The Bad:
I had high hopes the AIrVisual AQ forecast feature would help me plan outdoor activity by predicting windows of good air during California fire season. My hopes were unfounded: it is the worst “predictive” weather tool I have ever encountered! It would appear AirVisual’s forecast tool is based on the assumption that daytime pollution will simply dissipate overnight. With most of the West Coast on fire, the question is how much new smoke prevailing winds are bringing our way, and AirVisual’s forecast feature is clearly not built to gauge this, whether by visual smoke imaging or by other means.
