台灣空污警報 is a lifestyle app that delivers real-time push notifications when air quality in Taiwan worsens or improves. Users can set specific locations as notification focal points, receiving immediate alerts when air quality changes. The app also offers basic weather forecasts for selected locations.

The service primarily fetches the "Air Quality Index" (AQI) provided by the "Environmental Protection Administration, Executive Yuan." The AQI is calculated based on six pollutants: SO2, NO2, PM10, PM2.5, O3, and CO, with hourly updates. Higher values and darker colors indicate more severe air pollution levels and greater health risks. The app monitors these values and sends push notifications when air quality deteriorates or improves.
