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

Metal Detector is an app that will become indispensable in finding metal objects nearby: lost keys, coins, wires in walls, etc. The app detects metal objects by measuring the magnetic field level as it gets closer or farther from magnetic metals (e.g, iron, nickel, steel and alloys). A magnetic field is measured with the magnetic sensor built into your smartphone. Please note that the app will not detect silver, gold and copper coins since they have no magnetic field. The app also has a set of basic tools including a virtual tape measure, ruler, protractor and level tool. KEY FEATURES: • Metal detector; • Virtual tape measure; • Protractor; • Ruler; • Level tool. Please choose from our standard subscription options below: 1-week subscription from $0.99; 1-month subscription from $2.99; 12-month subscription from $5.99.
