## What is Air Quality Index?

Air Quality shows you what is actually in the air — where the smoke is, where it is heading, and what the air is like at any point on Earth you tap.

See the smoke before it arrives
A 48-hour NOAA HRRR forecast for the continental US and Alaska, hour by hour, at ground level and through the whole air column. Scrub the timeline and watch a plume move. Outside the US, Copernicus CAMS gives you five days of global smoke, dust, and haze.

Air quality across a whole country, not a scatter of dots
The US air quality map draws the hourly AQI as a continuous field from EPA AirNow, with a second layer for tomorrow’s forecast. Monitor readings ride on top as pins you can tap. Community sensor readings from OpenAQ cover the rest of the world.

A forecast anywhere, not just where a weather station is
Tap or press and hold any point on the map for a five-day air quality forecast — a stretch of coastline, a trailhead, a valley with nobody in it.

Layers you choose
• Ground-level and column smoke, 48 hours (NOAA HRRR)
• Global smoke, dust, haze, PM2.5 and aerosol, 5 days (Copernicus CAMS)
• US air quality index, now and tomorrow (EPA AirNow)
• EPA monitor readings and worldwide community sensors
• Active wildfires and satellite heat detections (NASA EONET, NASA FIRMS)
• Daily satellite photography (NASA GIBS)
• Volcanoes (Smithsonian Global Volcanism Program)
• Pollen forecasts for six species across Europe

On every screen you own
Widgets and complications for a glance. An Apple Watch app with the reading and a five-day chart. An interactive 3D globe on Apple Vision Pro. An ambient satellite flyover on Apple TV. Multiple windows, a sidebar and a menu bar item on Mac.

Free and private
No price, no subscriptions, no ads, no accounts. Your location is used to show you the air where you are and never leaves your device.

Data from NOAA, Copernicus Atmosphere Monitoring Service, EPA AirNow, NASA, OpenAQ, Open-Meteo and the Smithsonian Institution. Air quality data is provided as published and is not a substitute for official public health guidance.

### 1/5 — Non-existent

*2026-08-10*

There is no “gulf of America”. If the developer cannot get that basic information correct they cannot be trusted with anything more complex.

### 5/5 — Pat

*2026-08-07*

Thank you for this wonderful site. The ability to see this smoke move over time has allowed me to plan my outdoor activities and avoid toxic pollution.

### 1/5 — Limited coverage

*2023-09-04*

Like previous reviewer said, the App only covers the southern part of North America. It would be a cool App if it covered all North America.

**Developer response:** Hello! I'm sorry it took so long, but world wide coverage (including Canada) is finally available! Give it another look when you can. Cheers.

### 5/5 — thank you for this free app!

*2023-08-02*

this app is great and exactly what I needed.

### 2/5 — 2 star

*2023-06-08*

Super glitchy doesn’t work well

### 2/5 — Probably okay for the south!

*2023-05-17*

The app itself looks decent but won’t let you see northern parts of the country up close. Probably fine for the south, or the USA ¯\_(ツ)_/¯

### 5/5 — Straight forward, simple and amazing

*2022-06-24*

App does exactly what it needs to do with great UI, seamless graphics, and clear data on the current air quality and the forecast.

### 5/5 — Go daddio!

*2022-06-22*

This is well done!

### 5/5 — Simple, elegant, functional

*2022-06-17*

Love the simple and elegant presentation of smoke data.

### 5/5 — Simple and does what it say well

*2022-06-16*

This app does exactly what you’d expect it to - but does it really well!

## Version history (last 5 releases)

### 2.0.2 — 2026-08-22

Apple Watch
A new watch app shows the air quality where you are, with a five-day forecast on the next screen. Complications put the current reading on your watch face.

Widgets
Home Screen and Lock Screen widgets showing the current reading and what is coming.
A US air quality map, not just dots on one
“US Air Quality Index” draws the hourly AQI as a continuous field across North America, so you can see the shape of the air between the monitors rather than a scatter of pins. “US Air Quality Index Tomorrow” does the same for tomorrow’s forecast. Both come from EPA AirNow.
EPA monitor pins now come from our own service rather than a shared dataset. They load faster and are more current.

Fixes
• Smoke forecasts no longer drop the occasional blank hour.
• Satellite imagery no longer leaves a black band down the international date line.
• Background refresh is more reliable, so the map is current when you open it.

Free, as always: no accounts, no ads, no subscriptions. Your location never leaves your device.

### 2.0.1 — 2026-08-01

Minor bug fixes around projection of the HRRR Smoke Tilesets

### 2.0 — 2026-07-29

Finally: Worldwide Support!

New datasources added:
• Worldwide smoke, dust, and haze forecasts, with playback up to five days ahead.
• 48-hour Alaska smoke forecasts.
• NASA satellite imagery and active fire hotspot layers.
• Global air quality sensors, volcanoes, wildfire events, and European pollen forecasts.
• Five-day AQI forecasts for searched places, map locations, sensor stations, and your current location.
• Home Screen and Lock Screen AQI widgets for configurable locations.
• Climate and science resources, an in-app feedback form, and support for 36 languages.
• Improved accessibility with better VoiceOver support, Dynamic Type, larger controls, Reduce Motion support, and keyboard navigation.
• Improved map performance, forecast loading, animation, and handling of dense groups of map markers.

### 1.1.2 — 2025-07-30

• Fixed an issue where the app could use excessive storage space over time

Smoke overlay image download speed improvements.
