City Guide & Air Quality
Taiwan's official air quality data, station by station. Plus YouBike availability and Taipei public trash cans — all on one map.
Color-coded pins and heatmaps using Taiwan Ministry of Environment-aligned tiers. Switch between AQI, PM2.5, ozone, and more to see what is driving the index near you.
Check available bikes and empty docks at every YouBike 2.0 station in Taipei and Taichung — right alongside the air quality picture for the same trip.
Toggle the trash can layer to see clustered pins of public bins across Taipei. No more wandering — tap and walk to the nearest one.
Standard, satellite, and hybrid map styles. Tap any station for a full detail sheet — pollutant breakdown, last update time, and current status.
Every station tells you more than one number. Open any pin to see all measured pollutants, station status, and when data was last updated.
Full English and Traditional Chinese support. Clean, map-first interface designed for quick daily decisions.
Available on the App Store for iPhone.
