AirPro v2 is an Android application developed by ANYSEN that offers real-time fine dust information. The app requests background location information to use the widget. It does not have any advertising or analytical purposes; it is only intended to provide simple information.

Korea ranks 173rd out of 180 countries in terms of air quality, with the lowest air quality among OECD countries. AirPro offers a solution to this problem by providing real-time air quality information for indoor and outdoor environments. The app has several features that make it stand out, including the first domestically verified fine dust measurement device, AirPro PM2.5. It is more precise than the nationwide measurement network and provides information closer to real-life environments. The data collected is available in real-time through Microsoft Azure cloud, with numerical values and graphs that display the hourly trend of fine dust levels. The app also provides fine dust information and response measures based on Korean and WHO standards.
