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. Not only does it help you identify potential sources of harmful EMF, but it also provides guidelines on the allowed limit for continuous and prolonged exposure, helping you make informed decisions about your environment. Plus, it stores the higher measures of magnetic fields with a date stamp for each event, allowing you to monitor your exposure over time. Magnetic fields are measured in nT (nanoTesla) and/or milligauss (mG). Customize your screen colors, calculate the magnetic force in nano tesla (nT), and store your records for future reference. Don't leave your health to chance. Take charge of your surroundings and shield yourself and your loved ones from harmful EMF radiation. Take control of your environment and protect yourself and your loved ones from harmful EMF radiation. Health is our most important asset. +++ 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. -Magnetic force is calculated in nanoteslas ( nT ) -Record your readings with a date stamp of each event. -Store your records. -Change colors of your screen.
