About this app
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.…

Independent evidence report
Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
