AirDust: your personal Air Quality, UV & Pollen tracker — live data on your wrist.

The FREE version reads live air quality from the community-run Sensor.Community network — real sensors that hobbyists host on their balconies and gardens, searched within about 2 km of your location. No account, no sign-up.

FREE — FOREVER
• Live PM2.5, PM10 & Air Quality Index (AQI) from nearby Sensor.Community sensors
• Nearby sensor lookup (~2 km search)
• Fast quick-glance view
• AQI Legend & About screens
• Official EPA-2024 air-quality scale

PRO — OPTIONAL €5 ONE-TIME (covers backend & data costs, keeps the free tier alive)
Everything in Free, PLUS it works ANYWHERE — even where no community sensor is nearby — because Pro uses our backend, which layers several sources:
• Air quality: Sensor.Community first, then OpenAQ reference stations (within 25 km), then a Google modeled estimate as a last resort. The number shown is the outlier-filtered AVERAGE of all live sensors within your radius — not a single station.
• Pollen forecasts — Tree, Grass, Weed (Google Pollen, 5-day)
• UV Index, peak time & 3-day forecast
• Temperature & humidity — from nearby sensors, or weather providers where none report
• Hourly air & weather forecast (up to 6h)
• Historical trend charts
• Altitude advisory — warns when your elevation differs from the sensors feeding your reading
• Custom Pollen/UV alerts with thresholds
• PM-vs-limit reference screen

Free and Pro use the SAME EPA-2024 scoring — Pro just reaches more data sources.

THE MENU (press MENU)
• Location — your spot or a Saved Location
• Sensor List — nearby sensors
• Legend / About / Exit
Pro adds: History, Pollen & UV Alerts, PM Limits, Alert Toggles, and App Mode (run the widget as Pro or Free without removing your key).

SEEING "NO SENSORS NEARBY"? (Free)
Free needs a real community sensor within ~2 km, and coverage varies a lot — some areas simply have none. A Saved Location only helps if there ARE sensors near those exact coordinates; pointing it at an empty area still shows nothing. To try:
• On the watch: MENU → Location → Saved Location 1
• In Garmin Connect: AirDust → Settings → Locations → "Saved Location 1:" → enter coordinates as 42.123456,23.123456
• See where sensors actually exist at maps.sensor.community
If your area has no community sensors at all, Pro is the way to get a reading anywhere.

UPGRADE TO PRO
Visit https://airdust.safescanapp.app on your phone or computer, pay €5 (secure, one-time), get your code instantly, and paste it into AirDust Settings in the Garmin Connect app.

YOUR PRO KEY IS SAFE
Your key is tied to your watch, not the install. If you reinstall or update AirDust, Pro comes back automatically once your watch syncs with your phone — nothing to re-buy or re-enter. (A key works on one watch at a time.)

UPDATES & SETTINGS (a Garmin quirk)
Garmin doesn't always download the newest version or your settings automatically. If AirDust looks outdated or a setting won't apply:
• Garmin Connect (phone) → Connect IQ Store → My Apps → AirDust → Update (or reinstall — your Pro key is safe)
• Keep your watch connected & synced over Bluetooth
• After updating, re-open AirDust Settings and Save again
• Desktop: Garmin Express → device → Connect IQ Apps → Update
Your version shows on the About screen.
