See the air you’re actually breathing. Most apps give you one AQI number for your whole city. Paku shows you live readings from thousands of PurpleAir and AirGradient sensors, so you know when it’s safe to open the windows, go for a run, or send the kids outside. → A map of real, live sensors Every public PurpleAir and AirGradient sensor on a fast, beautiful map, indoors and out, with AQI, temperature, humidity, and how they’re trending. Official AirNow government stations are on the map too, and a Data Sources screen lets you choose which networks you see. Smart Select picks the most reliable sensor near you, not just the closest one. → Widgets for every screen Put the nearest sensor, a favorite spot, or your own sensor on your Home Screen, Lock Screen, Apple Watch, or Mac desktop. Glance, then get on with your day. → Alerts that beat the smoke Set a threshold on any sensor and Paku will notify you the moment it’s crossed, then again when the air clears. Nearby alerts can even follow you, watching the closest sensor as you move, entirely on your device. If you live with wildfire smoke or winter inversions, this feature is for you. → Live Activities Keep the AQI and its trend
