01
Search any US address or use your current location to check what's nearby.
02
Cell towers, power lines, and substations on an interactive map, with exact distances.
03
A clear 0–100 EMF score, so you can make informed decisions about where you live.
RF (towers · 2 mi) + ELF (power grid · 1 mi) = EMF SCORE 0–100
Lower is better · RF covers towers within 2 mi · ELF covers power lines & substations within 1 mi

A government minister in Mizoram recently made a public visit to inspect smart meter installations after residents raised complaints, according to The Times of India. While the article's details on the specific nature of those complaints are limited, the fact that a state official felt compelled to personally check on the rollout suggests real concerns among consumers — concerns that are becoming increasingly familiar as smart meters and other wireless infrastructure spread into more homes and neighborhoods worldwide.
Here's a headline that caught our attention this week: India is reportedly raising its permissible EMF exposure limits, a move described as beneficial for the country's 5G rollout. The full details of the policy change are still emerging, but the headline itself tells health-conscious readers something important — as 5G networks expand, regulatory limits on radiofrequency exposure are being adjusted to accommodate more infrastructure, not less.
WHOOP, the wearable brand best known for tracking sleep and recovery in fitness circles, is reportedly moving into new territory: health screenings and cancer detection. For families who already keep a close eye on the everyday tech in their homes, this kind of news is a good reminder that our relationship with wearables and health devices keeps getting more complicated.
