AirScope: Pollen & Air Quality

Know exactly what you're breathing - and where the reading comes from.

AirScope is a hyper-local air quality tracker, pollen count forecast, wildfire smoke map, and real-time NOAA weather radar in one free app. Every air quality reading is labeled Measured, Combined, or Estimated, so you know how much to trust it - something no other air pollution app shows you.

AIR QUALITY & POLLUTION TRACKER

Real-time and forecast AQI (Air Quality Index) with a clear Good-to-Hazardous category, not just a color. Full air pollution detail for PM2.5, PM10, ozone, NO2, SO2, and CO with hourly forecast graphs. AirScope blends EPA-grade ground stations, satellite sensing, and atmospheric modeling to use the most accurate source available for your location.

POLLEN COUNT, DOWN TO THE SPECIES

Daily pollen counts and a 5-day allergy forecast for tree, grass, weed, ragweed, and mold spores - including the predominant species. Know whether it's cedar, oak, birch, juniper, or ragweed behind today's hay fever.

ALLERGY & POLLEN ALERTS

Set a pollen alert for any location and get notified when allergens are forecast to run high. Choose your threshold - Moderate, High, or Very High and above - and whether the alert arrives morning or afternoon. No noise, no daily spam.

WILDFIRE SMOKE TRACKING

Animated NOAA smoke forecasts covering near-surface smoke, vertically integrated smoke, and surface visibility, plus satellite fire detections and radiative power. Track a smoke plume as it moves toward you.

POLLEN WIDGETS

Home screen widgets showing today's tree, grass, weed, and mold pollen levels at a glance, in small, medium, and large sizes.

HEALTH INDICES

Daily risk levels with plain-language guidance for asthma, COPD, sinus headache, migraine, dust and dander, cold and flu, and arthritis - plus activity indices for running, biking, hiking, and dog walking.

SYMPTOM DIARY & TRENDS - PRIVATE BY DESIGN

Log how you feel each day alongside the air quality and pollen you were exposed to. Trend charts line your diary up against real pollution and pollen levels over 7, 30, or 90 days, so your triggers emerge. Your health data stays on your device.

MAPS & NOAA RADAR

High-resolution weather and air quality maps animate up to 15 days (10-day history plus 5-day forecast). Tap anything - a storm cell, a fire, a smoke plume, an alert - for an instant detail card. Satellite and Hybrid views included.

Map layers include:
• Air Quality Index (AQI)
• Tree, Grass & Weed Pollen - current and animated forecast
• Mold Spore Forecast - animated
• PM2.5, Ozone & Surface Dust Forecasts - animated
• Near-Surface Smoke, Vertically Integrated Smoke & Surface Visibility
• Fire Detections & Fire Radiative Power

• GOES Infrared Satellite - East & West
• Temperature, Pressure, Wind & Cloud Coverage
• Global pollutant maps - PM2.5, PM10, Ozone, NO2, SO2, CO, CO2
• NWS Warnings, Watches & Advisories (US)

NO ACCOUNT. EVER.

No sign-up, no login, no profile. AirScope has never asked for an email address and never will - built to inform you, not to profile you.

FREE TO USE

Every map layer, radar, forecast, pollen alert, and health feature is free - there is no paywall on data. Free users see ads; the optional AirScope Premium subscription ($0.99/month or $4.99/year) removes all ads and unlocks the medium and large widgets.
