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.\n\n→ A map of real, live sensors\nEvery 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.\n\n→ Widgets for every screen\nPut 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.\n\n→ Alerts that beat the smoke\nSet 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.\n\n→ Live Activities\nKeep the AQI and its trend in the Dynamic Island or on your Lock Screen while smoke moves through.\n\n→ Your own sensors\nOwn a PurpleAir sensor? Add your private sensors and use them everywhere: on the map, in widgets, and with alerts.\n\n→ Siri, Spotlight, and Shortcuts\nAsk Siri for the air quality nearby, check it from Spotlight, or use the AQI in automations, like turning on the air purifier when the number starts climbing.\n\n→ On every device, in sync\niPhone, iPad, Apple Watch, and Mac, with a live reading in your menu bar. Favorites and settings sync over iCloud.\n\n→ Private by design\nYour location never leaves your device. No account, no tracking, no data collection.\n\nA few things reviewers have said:\n\n“Does one job, does it very well, and keeps getting better... I wish all software was like this.”\n\n“Seriously impressed by this app. It’s the perfect companion to my PurpleAir outdoor sensor.”\n\n“Ten stars.”\n\nPaku 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, and private sensors are part of Paku Pro, a small subscription or one-time lifetime unlock that keeps everything running. The map, the widgets, and the rest are free.","facts":{"developer_id":990789831,"developer_url":"https://paku.app","first_released":"2020-10-02T07:00:00Z","support_url":"https://paku.app/","privacy_url":"https://paku.app/privacy","website_url":"https://paku.app/","app_version":"7.4.1","release_notes":"→ Small bug fixes to the widget so it consumes less data.","rating_current_version":4.72829,"rating_count_current_version":10986,"star_counts":[213,109,272,1257,9128],"genres":["Weather","Health & Fitness"],"languages":["EN"],"content_advisories":null,"device_families":["mac","watch","iphone","ipad"],"made_for_iphone_duo":null,"chart":null},"freshness":{"apple_read_at":"2026-10-22T21:24:12.739Z","catalog_read_at":"2026-10-17T17:46:13.443Z","reviews_checked_at":null,"summary_written_at":"2026-10-17T02:17:13.386Z","placed_at":"2026-10-15T10:21:36.034Z","scored_at":"2026-10-23T01:41:13.045Z"},"editorial":{"one_liner":"Live AQI readings from PurpleAir, AirGradient and AirNow sensors on a map, with widgets and threshold alerts.","what_is":"Paku is an air quality app that shows live readings from public PurpleAir and AirGradient sensors, plus official AirNow government stations, on a map.
