About

Electromagnetic EMF Detector

This app simulates detecting electromagnetic fields and electrosmog using your device's compass. It identifies ferromagnetic metals and can alert you to potential sources of radio-frequency EMF from common household appliances. While intended for entertainment, it records measurements with timestamps and offers a guide to radio-frequency guidelines.

Highlights
  • Simulates EMF and electrosmog detection
  • Detects ferromagnetic metals
  • Warning beep near emissions
  • Records measurements with timestamps
  • Table guide for radio-frequency guidelines
  • Detects magnetic force on three axes

This app is intended for entertainment purposes only and does not provide true electromagnetic and electrosmog detector functionality. Track magnetic fields near you. A warning beep will be activated to warn you. The app detects ferromagnetic metals using the iPhone's built-in compass feature. Also works as Electrosmog (EMP) detector. Detect many kinds of home appliances that create radio-frequency EMF. For example:plugs,cell phones,routers, baby monitors, doorbells, intercom systems,night alarm clocks, electronic appliances , electrical wire, antennas. You can check the limit allowed in the "Radio-Frequency Guidelines - for continuous and prolonged exposure" in the instructions button of this app. The higher measures of magnetic fields are stored. Even the time when the measure was taken, so you can locate the source of magnetic emission. Note: This app will not work on an iPod Touch, since it does not have a compass hardware. +++ FEATURES: -Track high magnetic fields and when has it been measured. -Table guide "Radio-Frequency Guidelines - for continuous and prolonged exposure". -Warning beep near focus emissions. -Detect the strength of Magnetic force fields on all three axis’s (x,y,z). -Magnetic force is calculated in microteslas ( µ T ) -Record your readings with a time & date stamp of each event. -Store until 100 records. -Send measures by email. If you have any issues to report or suggestions to make, please email the device you’re using, iOS version, and a detailed description of the problem to bellostudios@gmail.com
