Since the area you live in is set in the app, the information displayed is as simple as the required area.
In addition, you can check not only the amount of scattering at the current time, but also the amount of scattering for 24 hours or the last week on a graph.

The image shows whether the current amount of scattering is high or low.

The source of the measurement data of PM2.5 scattering amount is "Ministry of the Environment Air Pollutant Wide Area Monitoring System Soramame-kun".
