AIRQQ : Local AQI & PM2.5

Breathe easy with AirQQ, the ultimate hyper-local air quality and pollution monitor. Unlike standard weather apps that rely on broad, estimated satellite models, AirQQ aggregates real-time PM2.5 data from thousands of physical sensors right in your neighborhood. By seamlessly combining local PurpleAir laser particle counters, public WAQI network stations, and Open-Meteo global forecasting, AirQQ calculates the most accurate, hyper-local air quality average available. Whether you are tracking wildfire smoke, seasonal smog, or just checking if it is safe for an outdoor run, AirQQ gives you the exact data you need at a glance. 🌟 KEY FEATURES 🌟 📊 Interactive 24-Hour Trend Charts Never get caught off guard by shifting winds. Our beautifully rendered 24-hour charts show you both historical data and future PM2.5 forecasts. Simply tap, hold, and drag your finger across the chart to scrub through the timeline and view exact hourly pollution levels alongside visual health thresholds. 🗺️ Interactive Sensor Map & Custom Sources Want to track a sensor down the street? Open the built-in interactive map to browse the global network of active sensors. With a single tap, you can copy and add any specific sensor to your customized city dashboard. You can even paste PurpleAir Widget scripts or Map URLs directly into the app! 📶 Smart Offline Mode No internet? No problem. AirQQ automatically caches your city data, charts, and sensor readings. If you lose connection, the app instantly loads your last-known data so you are never left completely in the dark. 🎨 Deeply Customizable UI Make the app yours. In the Settings tab, you can finely tune every visual element. Adjust the size of the city text, the main AQI numbers, or the detailed descriptions. 💨 Live Particle Visualizer A stunning, real-time background particle animation visually represents the current air quality. Watch the particles shift in color and density based on the exact PM2.5 reading. (And yes, you can adjust their size and speed in the settings!) 🛡️ Health & AQI Standard Alerts AirQQ automatically color-codes your environment based on publicly available Environmental Protection Agency (EPA) Air Quality Index standards. From "Good" (Green) to "Hazardous" (Purple), you will get detailed health implications letting you know when sensitive groups need to stay indoors. 🌍 Multi-City Tracking Easily search and add multiple cities around the world. Rearrange your list with a fluid drag-and-drop interface, and swipe effortlessly between your saved locations. ⚠️ DISCLAIMER OF NON-OFFICIAL STATUS AirQQ is an independent, private application developed for informational purposes.
