> 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.

A simple yet effective EMF detector! The detector is as ACCURATE as the sensor of your device. You can use this simple application to detect EMF (Electromagnetic Fields). Which is given off by many electrical devices, power cables and even ghosts! Its suitable for paranormal investigators. And for detecting dangerous levels of EMF within your environment. Our EMF Analytics app offers more functionality and sensory data than most competitive apps. The live EMF reading is shown, as well as previous readings with the timelapse graph. You can switch between Mirotesla (uT) and Milligauss (mG) measurement units. The minimum and maximum readings or also kept on screen throughout your session on the app. The large bright LED's with different colours will show the strength level of the EMF. Sound and vibrations can be turned on and off so you don't miss any spikes. We have included a light option to turn your devices flashlight on and off. Which is ideal for paranormal investigations who wish to ghost hunt in the dark. X, Y, Z readings also help show the axis on which the strongest readings are being detected. Features - Current EMF reading displayed - Previous EMF readings are shown on the graph - The minimum and maximum readings are displayed - Toggle for Mirotesla (uT) and Milligauss (mG) - Flashlight can be turned on and off - Large coloured lights show EMF reading strength - Sound and vibration can be turned on and off - Screen will not lock whilst in use - Well-presented UI - X,Y,Z axis displayed This app uses the built-in magnetic sensor (compass) inside your device. And displays the live reading with a line of coloured LEDs, giving you a clear view of EMF levels. You can switch between units of measurement Mirotesla (uT) and Milligauss (mG) quickly and easily with a toggle button. You can use this application to quickly measure and magnetism and electromagnetism, earths geomagnetic field, ghosts and electrical devices. It can be used as a detector for EMF, magnets, metals, ghosts and paranormal entities. IMPORTANT: This app uses your devices built in magnetic sensor. If your phone or device does not have this sensor, the app will not display any measurements. If the readings are 0, it means that this app is not able to work on your device.

ReceptionRating · Positive reviews · Number of ratings

EMF Radiation Detector Reader holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: EMF Radiation Detector Reader has 4.7K ratings behind it against 69, so its average is the more settled of the two. Written reviews complicate that: 53% of EMF Radiation Detector Reader's written reviews are positive against 66% of EMF Analytics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EMF Radiation Detector Reader ships an update every 7 months, EMF Analytics every 2 days. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
