Two things happened in the last month that made the case for keeping a wildfire smoke app on your Android home screen. NOAA’s GeoXO program, the next-generation satellite line meant to sharpen smoke plume tracking across North America, was pulled back under the current round of budget cuts. And FIFA had to publicly review air quality risk before Sunday’s final, with the White House sitting in on the call. The federal early-warning stack is thinning, and the tournaments and school districts that depend on it are hedging with consumer apps.
The best wildfire smoke tracking apps for Android in 2026 pair fire perimeter data with air quality readings so you get both signals in one glance: is a fire nearby, and is what it’s throwing into the air already at your window. We looked at what public land agencies, wildland-firefighter reporters, and PurpleAir sensor owners actually keep installed, then picked seven that cover the full range from a US EPA official app to a community-run sensor network.
What to look for in a wildfire smoke app
Not every air quality app handles fires well, and not every fire app tracks smoke. The ones worth installing usually cover four things at once.
- Real-time fire perimeters, not just static incident lists. Look for VIIRS and MODIS infrared satellite hotspots.
- Two AQI sources, ideally one government (AirNow) plus one hyperlocal (PurpleAir).
- Push notifications that fire on evacuation orders and short-term AQI spikes, not just daily digests.
- Offline maps or cached data. Cell service goes first when a fire is close.
A useful bonus: rain-gauge and river-gauge data. The same conditions that spark wildfires often trigger flash floods days later.

The apps
1. Watch Duty – Best for real-time fire alerts you can act on
Watch Duty is the app that outperformed the federal alert chain during the January 2025 Southern California fires, when it hit the top of the iOS free chart in a single weekend. What makes it different is the source of the data: active and retired wildland firefighters, dispatchers, and first responders who file vetted reports, not scraped scanner feeds and not AI-generated summaries. As of June 2026 it also covers flash floods nationwide, with river gauges and precipitation feeds sitting alongside the fire perimeters.
Push alerts are the main event. You draw a region around home, work, or a relative’s neighborhood, and the app pings when an evacuation order, warning, or new incident lands. Infrared satellite hotspots (VIIRS and MODIS) and wind data are layered on the same map. The team runs on donations and full-time staff plus roughly 250 volunteers.
Where it falls short: Coverage is US-focused, so travelers outside the US or Canada get thin data. The volunteer reporting model also means non-Californian regions can lag by a few minutes on the newest starts.
Pricing:
- Free: Full app, no ads, forever
- Paid: $25/year membership unlocks supporter perks; the reporting stays free
Platforms: Android, iOS
Bottom line: If we could keep only one wildfire app on Android, this is it.
2. IQAir AirVisual – Best for AQI forecasting
IQAir AirVisual pulls from more than 500,000 government stations and validated citizen sensors. Its strength is the 3-day AQI forecast and long-term trend charts. Where AirNow gives you today’s reading, AirVisual tells you the next-72-hour trajectory well enough to plan a school run or a trip out of the zone.
Smoke events show up as a dedicated alert layer with a plume overlay, and the widget puts the current PM2.5 on the home screen. The paid tier adds source-attribution (how much of the reading is from smoke vs. traffic) and multi-city dashboards.
Where it falls short: The free tier is ad-heavy, especially when air quality is already bad. Some outdoor sensor readings run 10–15 minutes behind their government-grade sibling.
Pricing:
- Free: Global AQI, 3-day forecast, one location, ads
- Paid: Pro subscription from a modest monthly fee unlocks source attribution and multi-location
Platforms: Android, iOS, web
Bottom line: Pick this one when you need to plan ahead, not just react.
3. EPA’s AIRNow – Best for official US regulatory data
EPA’s AIRNow is the government-run app, and it is the reference other tools benchmark against. It reads from the same monitoring stations that feed the federal Air Quality Index, and it bundles the AirNow Fire and Smoke Map built with the US Forest Service. That map is what your local news station is usually screenshotting during a smoke event.
The app is free, has no ads, and no in-app purchases. Push notifications trigger when your saved location crosses an AQI threshold you set, and the Fire and Smoke Map layer overlays satellite hotspots with sensor readings from AirNow, PurpleAir, and Clarity in a single view.
Where it falls short: UI is dated, the map is slower to load than commercial apps, and coverage outside the US is sparse to nonexistent.
Pricing:
- Free: Everything, no upsells
Platforms: Android, iOS
Bottom line: The one you install when you want the same numbers your local health department is looking at.
4. Windy.com – Best for tracking where the smoke is going
Windy.com is a weather app first, but the smoke and particulate layers make it a legitimate wildfire tool. Turn on the CAMS smoke layer and you get a global map of PM2.5 dispersion with wind vectors on top, which is the fastest way to answer “is the smoke pointed at us tomorrow?” without opening three tabs.
Radar-style animation shows the next 24 hours of drift. The app also does regular weather (temperature, humidity, wildfire-fuel indicators like relative humidity below 15%), which makes it useful year-round rather than only in fire season.
Where it falls short: No official evacuation alerts. This is a forecast tool, not an incident app. Pair it with Watch Duty or AirNow for the on-the-ground signal.
Pricing:
- Free: Full map, all layers, no ads
- Paid: Premium from a modest yearly fee adds 1-hour animation steps and radar data
Platforms: Android, iOS, web
Bottom line: The best tool on this list for answering “which way is it blowing” a day ahead.
5. AirCare – Best hyperlocal aggregator for PurpleAir readings
AirCare blends PurpleAir’s citizen sensor network with EPA data and roughly 40 other government and university sources into one map. The result is a genuinely dense sensor grid in urban areas, where a single official monitor can miss microclimates that a PurpleAir sensor two streets over would catch.
The Android app adds pollen tracking and skin-relevant air data on top of PM2.5 and ozone, so it’s the pick for people who react to smoke plus seasonal allergens. Alerts run on user-set thresholds and a home-screen widget updates automatically.
Where it falls short: PurpleAir sensor readings can spike high in smoky conditions unless the app applies the US EPA correction, so cross-check occasionally with AirNow when the numbers look off.
Pricing:
- Free: All map data, one location, ads
- Paid: Pro from a modest yearly fee removes ads and unlocks multi-location alerts
Platforms: Android, iOS
Bottom line: The right pick when the official monitor is miles away and the PurpleAir sensor is on your neighbor’s roof.
6. PurpleAir Companion – Best for owning your own sensor
PurpleAir Companion is a third-party app built specifically for people watching one or two sensors closely, either their own or a public one at the end of the block. It handles per-sensor push notifications, which the official PurpleAir progressive web app cannot do reliably on Android.
Setup takes a minute per sensor: paste the sensor ID or pick from the map, set your AQI threshold, and pick whether the notification uses the raw PurpleAir number or the EPA-corrected version. That correction matters during wildfire smoke, when uncorrected PurpleAir readings can run 30–40 AQI points high.
Where it falls short: Zero forecasting. This app is entirely about the here-and-now number on a specific sensor. It is not the map you use to plan tomorrow.
Pricing:
- Free: Full functionality
Platforms: Android
Bottom line: The right app if you already trust PurpleAir and want per-sensor alerts your official app can’t send.
7. SmokeWx – Best for hour-by-hour smoke forecasts
SmokeWx is a specialist app that does one thing: hourly wildfire smoke forecasts for more than 20,000 cities and towns across the US and Canada. It pulls from the NOAA Air Resources Laboratory’s HRRR-Smoke model, which is the gold standard for near-term smoke prediction, and it updates multiple times per day as new fire detections come in.
The interface is a single scrollable timeline: current hour on top, then the next 24 to 48 hours of expected PM2.5, near-surface concentration, and vertically integrated smoke. It’s the kind of tool that wildland fire managers and USFS air resource advisers actually use, packaged for a phone.
Where it falls short: No fire perimeters, no evacuation alerts. It also assumes you know what “vertically integrated smoke” means, though the timeline speaks for itself when the numbers get red.
Pricing:
- Free: Full app
Platforms: Android, iOS
Bottom line: The unfair-advantage pick if you plan outdoor work by the hour.
How to pick the right one
- If you only install one: Watch Duty, and set an alert region around your home.
- If you plan outdoor time three days ahead: IQAir AirVisual for forecast, Windy.com for drift.
- If you trust government data first: EPA’s AIRNow.
- If you own a PurpleAir sensor or have one nearby: PurpleAir Companion or AirCare.
- If you schedule outdoor work by the hour: SmokeWx.
- The realistic setup for most fire-prone regions: Watch Duty for alerts, AirNow for the number, Windy for the map.
FAQ
What is the best free wildfire smoke tracking app for Android?
Watch Duty is the best free option. The full app is free forever, no ads, and reports are filed by vetted wildland firefighters and dispatchers. EPA’s AIRNow is a close second when you want government-grade air quality alongside the fire map.
Which app do wildland firefighters actually use?
Wildland firefighters and dispatchers are the ones filing reports into Watch Duty. For smoke forecasting they lean on HRRR-Smoke model output, which is exactly what SmokeWx surfaces on a phone.
Can I get push notifications for wildfire smoke?
Yes, on Watch Duty, AirNow, IQAir AirVisual, AirCare, and PurpleAir Companion. Each lets you set a location or region and an AQI or incident threshold. Watch Duty’s notifications are the most reliable for evacuation orders.
What’s the difference between PurpleAir and AirNow readings?
AirNow uses federal reference monitors calibrated to EPA standards. PurpleAir uses lower-cost citizen sensors that read PM2.5 differently, especially during wildfire smoke. During smoke events, apply the EPA correction (most apps in this list do this automatically) or cross-check both.
Do any of these apps work offline?
AirNow and Watch Duty cache your last known map and alerts, so you can still see the most recent state without cell service. Forecasts and new alerts require reconnection.
