This app allows you to detect electromagnetic fields (EMF) and magnetic radiation using your device's built-in sensors. It can alert you to high magnetic field measurements and potential radiation sources around you, such as appliances or electrical outlets.
Key features include tracking high magnetic field measurements with time stamps, receiving warning beeps near radiation, measuring magnetic force on three axes (x, y, z) in microteslas, recording up to 100 readings, and the ability to send measurements via email.
The app is available for free download and use, but it includes in-app purchases. This means you can use the core functionality without cost, but certain additional features or enhancements may require a purchase.
This app is designed to work with iPhones that have compass hardware. It will not function on an iPod Touch as it lacks this necessary component. It's important to note that the app is intended for entertainment purposes and does not provide true metal detector functionality.
You can use the app to scan your surroundings for electromagnetic fields. Place your device near appliances, electrical sockets, or other potential sources of radiation. The app will alert you to high readings and allow you to record them for later review.
