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
