Electromagnetic EMF Detector vs EMF Radiation Detector Reader
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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

> Detect Invisible Fields: Find the ElectroMagnetic Fields around you in seconds > Pro-Grade Precision: High-accuracy Magnetic Field Analyzer & Gauss Meter with Advanced Signal Stabilization. > Record, Analyze & Export: track trends with interactive data charts and save detailed logs for professional analysis. Check out the areas where you work (desk, meeting rooms), where you sleep (bed), where you relax (couch, living room) and find the levels of EMF you are exposed to. Also use the app to measure the fields emitted by your appliances (computer, fridge, speaker, phone...). PROFESSIONAL MAGNETIC FIELD ANALYZER & GAUSS METER: Discover the invisible magnetic world around you. Using your device’s internal magnetometer, the app provides a comprehensive look at the electromagnetic fields (ELF) generated by electronic devices, wiring, and ferromagnetic materials. NEW PROFESSIONAL FEATURES: - 3-Axis Vector Analysis: Real-time $x, y,$ and $z$ coordinate tracking for precise field directionality. - Interactive History Graphs: Visualize time evolution with high-resolution charts that track spikes and trends. - Clean Signal Mode (LPF): Toggle an advanced Low-Pass Filter to stabilize readings and remove sensor jitter for professional-grade clarity - Save & Export Logs: Record your sessions and export data for further analysis in external software. VERSATILE USE CASES: Electronics Inspection: Measure the magnetic footprint of computers, speakers, and home appliances. Metal Detection: Locate ferromagnetic objects like iron pipes or steel studs behind walls. Interference Calibration: Find the "quietest" zones for sensitive electronic equipment or audio setups. USER EXPECTATIONS & DISCLOSURE: This app is designed as a sophisticated utility for detecting Magnetic Fields (ELF). What it detects: Magnetic flux from magnets, ferrous metals, and the low-frequency electromagnetic fields emitted by electronic components, power supplies, and speakers. What it does NOT detect: This app is not a radio frequency (RF) scanner. It cannot detect Wi-Fi signals, Bluetooth, 5G cellular radiation, or microwave leakage. DISCLAIMER: - This app is intended for educational and utility purposes. It is not a substitute for certified industrial or scientific equipment. It does not provide medical advice or guarantee "safe zones" in a clinical sense. This app does not guarantee exact measures as other fields can interfere with the compass inside your phone, which is used to detect the fields.
