Your Desktop.
Your Air Quality,
UV & Weather HUD.
A sunny day doesn't always mean safe air. For people living with asthma or allergies, outdoor runners timing their workouts, parents protecting young lungs, and anyone in regions impacted by wildfire smoke or urban smog, knowing real-time PM2.5, NO₂, O₃, AQI, and UV Index is essential. WeatherWidget Pro acts as an Always-On Desktop Air Quality & UV Monitor—floating effortlessly on your wallpaper across up to 5 cities.
Why What You Can't See in the Sky Matters Most
Standard weather apps tell you whether to grab an umbrella, but they rarely warn you about what you're breathing until you're already outside. Fine particulate matter (PM2.5) from distant wildfire smoke penetrates deep into the lungs and bloodstream. Rush-hour Nitrogen Dioxide (NO₂) and afternoon ground-level Ozone (O₃) trigger airway inflammation, while high UV Index levels cause rapid skin and eye damage even on cool, breezy afternoons.
Whether you live with asthma or allergies, lace up as an outdoor runner or cyclist, check conditions as a parent before sending kids out to play, or live in a city affected by wildfire plumes or urban smog, WeatherWidget Pro gives you an Always-On Desktop Air Quality & UV Monitor. With live color-coded AQI badges and pollutant telemetry right on your desktop wallpaper, you'll know the exact moment to open your windows for fresh air—or close them and switch on your HEPA filter.
