AirScope: Pollen & Air Quality2.3.1 - App Store

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

AirScope combines hyper-local air quality, species-level pollen forecasts, wildfire smoke tracking, and real-time NOAA weather radar in one app. Every reading is labeled Measured, Combined, or Estimated, so you always know how much to trust it - something no other air-quality app shows you.

AIRSCOPE FEATURES
. Home Screen & Lock Screen Widgets - today's tree, grass, weed, and mold levels at a glance, without opening the app.
. Wildfire Smoke Tracking - animated NOAA forecasts of near-surface smoke, vertically integrated smoke, and surface visibility, plus satellite fire detections and fire intensity.
. Symptom Trends - charts that line your symptom diary up against pollen and pollution levels, so your personal triggers emerge over time.
. Health Indices - daily risk levels with plain-language guidance for asthma, COPD, sinus headache, migraine, dust & dander, cold & flu, and arthritis, plus outdoor indices for running, biking, hiking, and dog walking.
. Satellite & Hybrid map views, tappable detail cards for storms, fires, smoke, and weather alerts, dramatically faster loading, and full Spanish language support.

AIR QUALITY YOU CAN TRUST
Real-time and forecast AQI with a clear Good-to-Hazardous category - not just a color - plus pollutant 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, and always uses the most accurate source available for your location.

POLLEN, DOWN TO THE SPECIES
Daily pollen counts and 5-day allergy forecasts for tree, grass, weed, ragweed, and mold - including the predominant species affecting you, so you know whether it's cedar, oak, birch, or ragweed behind today's symptoms.

MAPS & RADAR
Interactive, high-resolution maps with animation up to 15 days (10-day history + 5-day forecast). Tap anything - a storm cell, a fire, a smoke plume, an alert - for an instant detail card.

Layers include:
. Air Quality Index (AQI)
. Tree, Grass & Weed Pollen (current + animated forecast)
