Know your
environmental risk
every single day.
Your Daily Environmental Health Score is a single number that combines air quality, water safety, home environment, and NatureRx Tracking into one clear picture of your environmental health — personalized to where you live.
Four dimensions, one score
Your daily score is calculated from real-time and historical data across four environmental health dimensions.
Air Quality
Real-time outdoor air quality including PM2.5, ozone, wildfire smoke, and nearby facility emissions.
Water Safety
Your public water system's violation history and contaminant levels, updated as new data is released.
Home Environment
Known hazards at your address — contamination events, Superfund proximity, indoor toxin risks.
NatureRx
Daily green space access and outdoor time via NatureRx Tracking — with recommendations for when and where to get outside.
Why it matters
A daily environmental health score changes how you understand your surroundings.
Before credit scores, most people had no clear way to understand their financial standing. Environmental health has the same problem — the data exists, but it has never been organized around you and updated daily in a format you can act on.
Your daily score changes that. Check it each morning like you check the weather. See how it shifts when air quality worsens, when you move neighborhoods, or when you swap your cleaning products. Small decisions become visible, and long-term patterns become clear.
