01 · How it works
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

If you're a parent tracking your child's fitness or monitoring your own health metrics with a wearable device, a new review from the Electronic Frontier Foundation (EFF) should give you pause. The digital rights organization recently examined wearable health device companies and found that most lack key privacy measures—a finding that has implications beyond just data security.
The wearable health tech industry is banking on a massive future market, even as current adoption rates remain sluggish. According to a recent report from Crain's Chicago Business, companies like Epicore Biosystems—which develops wearable sweat sensors—are optimistic about growth prospects despite consumers' hesitation to embrace these devices.
The growing trend of wearable health devices is reshaping how families approach preventive care at home, but health-conscious parents should consider both the benefits and the electromagnetic field (EMF) exposure that comes with these constantly-connected devices. What This Means for Your Home Environment Wearable identification and health monitoring devices are being positioned as tools for preventive healthcare in the home setting.
