ShanghaiAir

About this app

Know what Shanghai's air means before you step outside. ShanghaiAir turns current air-quality data into a clear AQI, practical health guidance, and the details behind the reading. Check the station nearest you, keep Shanghai ready by default, and save other cities or monitoring stations for quick comparison. AT A GLANCE • Current AQI and health category • Guidance for sensitive groups and everyone else • PM2.5, PM10, ozone, nitrogen dioxide, sulphur dioxide and carbon monoxide • Multi-day PM2.5, PM10 and UV forecasts • Temperature, humidity, wind and pressure • Nearby monitoring stations and saved places • A local trend that builds as you use the app • Home Screen widgets for a quick check • Light and Dark Mode Measurements are attributed to the reporting environmental agency and the World Air Quality Index Project. Times are shown in the monitoring station's local time. Location access is optional and used only when you ask ShanghaiAir to find nearby stations. You can use the app with saved places without sharing your location. Air-quality information is for general awareness and is not medical advice.
