AQI & Pollen: BreathShield

Air quality anywhere on Earth, not just near a monitoring station. 500 m global data, real US EPA AQI, pollen and UV for your exact spot.

BreathShield warns you BEFORE you get sick.

Wake up every morning to a personalized health risk score that combines your overnight Apple Watch biometrics with real-time air quality and pollen data. All processing happens entirely on your device.

HOW IT WORKS

• Fetches hyperlocal PM2.5, ozone, pollen, and UV index from nearby monitoring stations
• Calculates your personal risk score (0-100) using a weighted bio-environmental algorithm
• Sends smart morning alerts when your risk is elevated
