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

Turn your iPhone into an EMF detector and gauss meter. EMF Detector reads the built-in magnetometer and shows live magnetic field in microtesla, milligauss, or Gauss — the same units a handheld meter uses. This app measures magnetic fields. It does not measure Wi‑Fi, 5G, or ionizing radiation. What you can do • Live EMF detector with peak hold and average • Switch units: µT, mG, Gauss • Zero / calibrate to ignore Earth’s field and hunt nearby sources • Ghost hunt mode: audio and haptics on magnetic spikes (used by investigators as a starting point, not a spirit detector) • Metal and stud finder: sweep a wall to find studs, pipes and wiring • XYZ charts and field direction compass • Session log with CSV and PDF export Ghost hunt & metal Walk slowly. Zero the meter, then sweep. Spikes mean a changing magnetic field — speakers, transformers, studs, or wiring. Audio maps spike strength so you can hunt without watching the screen. Pro removes ads and unlocks direction, full history, high-EMF alerts, and PDF export.

Verdict

The call

The clearest difference is price: EMF Detector at Free against Electromagnetic EMF Detector's $1.99. EMF Detector also leads on rating (4.6 vs 4.4). Electromagnetic EMF Detector's advantage is ads (none vs shown) and review sentiment (79% vs 60%). On ratings volume, update cadence, in-app purchases and monetization model there is nothing between them.

EMF Detector is free to download; Electromagnetic EMF Detector costs $1.99 up front. Electromagnetic EMF Detector sells 2 one-off in-app purchases and EMF Detector sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

EMF Detector holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 212 and 108 respectively. Written reviews complicate that: 79% of Electromagnetic EMF Detector's written reviews are positive against 60% of EMF Detector's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Electromagnetic EMF Detector ships an update every 5 weeks, EMF Detector every 2 months. Both last shipped on November 6, 2026.
