Detect the electromagnetic fields near you, known as EMF. It's not necessary an expensive electronic equipment. Your device is already a sensor to detect EMFs. Track when a high magnetic field has been measured while you take the mobile with yourself. A warning beep will be activated to warn you and prevent health problems. Use "Electromagnetic detector" as a scanner or as a EMF detector to detect high risk wireless zones. Check if your bed is EMF free! Appliances, microwaves and sockets could be now radiating you. Convert your iPhone into a EMF Meter (electromagnetic field tester) or as a teslameter. By using the internal compass hardware. You can view the raw data of the magnetic fields that are all around you on a digital display. Over a thousand research studies have linked EMFs to important biological effects. EMFs have been associated with symptoms such as nausea, headache, fatigue, anxiety, mental confusion, memory loss, sleep disturbance, itchy or burning skin sensations, and skin rashes. The electromagnetic radiation come from broken or lose wires behind the wall, or electrical socket, appliances and other electrical devices in the home. Finding pipes or other metallic objects under ground or behind walls. Detecting the presence of ghost. Clocks and radios near the bed may also contribute. Exposures to EMFs from cordless phones, cell phones, wireless computer equipment, Wi-Fi, etc. Scientist, Teachers, Students, Engineers, all use EMF Meter's for detecting magnetic fields of all types. ***Features: -You can track when a high magnetic field has been measured and when, so the current time is stored. -Warning beep near focus radiation. -Detect the strength of Magnetic force fields on all three axis’s (x,y,z). -Magnetic force is calculated in microteslas ( µT ) -Record your readings with a time & date stamp of each event. -Store until 100 records. -Send measures by email. Please observe and respect the iPhone user manual and warranty if you intend to use your iPhone as a scientific device. We are not responsible for any damage that you or any other force of nature may cause to your device. Tips: You may calibrate the detector by moving the iPhone in the form of an 8. Note: This app will not work on an iPod Touch, since it does not have a compass hardware. This app is intended for entertainment purposes only and does not provide true Metal Detector functionality. This apps uses the magnetometer to measure the magnetic field when the iPhone is placed near feromagnetic metal objects. If you would like to have a feature added to this app. Please let us know, so that we can make this happen as soon as possible for you. Download it now to prevent stay near magnetic radiations! (EMF).

Measure electromagnetic fields (EMF) in real time using your smartphone's built-in magnetic sensor. [Key Features] • Real-time magnetic field strength display (switch between µT / mG) • Automatic saving of measurement data and history management • Map view of measurement locations • Sound alarm (volume changes with field strength) • Color themes (11 in total — dark and light pastel) • Ad-removal option (one-time purchase; also unlocks some color themes) [Great For] • Anyone concerned about magnetic fields around home appliances or power lines • Anyone who wants an easy alternative to a dedicated EMF meter • Anyone who wants to record and manage measurement data * This app uses your smartphone's magnetic sensor. Its accuracy differs from that of a dedicated measuring instrument.

Verdict
The clearest difference is price: EMF Scan at Free against Electromagnetic Detector PRO's $4.99. EMF Scan also leads on update cadence (weekly vs every 14 months). Electromagnetic Detector PRO's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
