About this app
See the air you’re breathing. Paku shows you live readings from tens of thousands of PurpleAir sensors, so you know when it’s safe to open the windows, go for a run, or let the dog out. → A map of live sensors Every public PurpleAir sensor on a fast, beautiful map, indoors and out, with AQI, temperature, humidity, and how they’re trending. Turn on AirNow to see official government stations too. 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 private 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. Perfect for wildfire smoke or winter inversions. → Live Activities Keep the AQI and its trend in the Dynamic Island or on your Lock Screen while smoke moves through. Live Activities can even start automatically when the AQI crosses a threshold. → Your own sensors Own a PurpleAir sensor? Add your private sensors and use them everywhere: on the map, in widgets, and with alerts. → Siri, Spotlight, and Shortcuts Ask Siri for the air quality nearby, or use the AQI in automations, like turning on the air purifier when the number starts climbing. → On every device, in sync iPhone, iPad, Apple Watch, and Mac, with a live reading in your menu bar. Favorites and settings sync over iCloud. → Private by design Your location never leaves your device. A few things reviewers have said: “Does one job, does it very well, and keeps getting better... I wish all software was like this.” “Seriously impressed by this app. It’s the perfect companion to my PurpleAir outdoor sensor.” “Ten stars.” Paku is made by one person, not a company. No growth team, no engagement tricks, just an app I use every day and keep making better. Alerts, Live Activities, private sensors, and a few of the fancier widgets are part of Paku Pro, a small subscription or one-time lifetime unlock that keeps everything running. The map, the standard widgets, and the rest are free.
