The Standalone version of the EMF Detector . The difference from the free and Pro versions is that the standalone is just the advanced meter as requested by the community. This version does NOT contain the classic and the simple variants. If you want them you should donwload the free or the Pro version.The detector is as ACCURATE as the sensor of your device. The StandAlone has: The Pro has: --\u003eNo ads --\u003eRecorder to save data to text file for later use on a computer --\u003e3 sound alerts: Max, Spike and Radar --\u003eVibration alert --\u003eVariable sampling rate --\u003eA few backgrounds and skins for the detector. Use this simple app to detect electromagnetic fields and metals and amaze your friends with what your phone can do. Watch out because some people believe that sudden changes in the EM field might indicate the presence paranormal entities :p. The new themes offer the user greater accuracy, graphs of the displayed readings and even the ability to calculate and show the auxiliary field H which is calculated from the magnetic field. The simple theme makes it easier for inexperienced users to measure and study magnetic fields. You can use this app to measure and study magnetism and electromagnetism, the earths geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices and even (as some people believe) entities and ghosts. This app uses the magnetic sensor(compass) of your phone and displays the reading with a line of LEDs and a classic needle meter. You can switch between units of measurement (uTesla and Gauss) and change the range of measurement from the settings. --------\u003eNOTE that this app uses the magnetic sensor. If your phone doesn\u0027t have this sensor the app is NOT going to display any measurements. If you open the app and the readings are 0 it means that this app can\u0027t work on your phone. Please uninstall the app and dont leave bad reviews.Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it. Use at your own risk. Thank you.\u003c-----
