Ultimate EMF Detector Free

Detect electromagnetic fields with Ultimate EMF Detector Free, a straightforward EMF meter that leverages your phone's built-in magnetic sensor to measure real-time electromagnetic activity around you.

Whether you're curious about geomagnetic fields, investigating electromagnetic radiation from household devices, or exploring the science of magnetism, this app delivers accurate readings directly from your phone's sensor hardware. The detector displays measurements in multiple units—microTesla, Gauss, and milliGauss—so you can work in whatever format suits your needs. You'll also get the auxiliary field H measurement in amperes per meter for deeper electromagnetic analysis.

The interface combines a classic analog needle meter with a modern LED line display, giving you instant visual feedback on electromagnetic fluctuations. Switch between measurement units and adjust the range from settings to fine-tune your readings. Advanced users gain access to XYZ axis breakdown, max-min value tracking, and detailed graphs that reveal patterns in electromagnetic activity over time. The app includes a keep-screen-on button so readings stay visible during extended monitoring sessions.

A powerful recorder feature lets you capture live data directly to a text file, which you can transfer to a computer for detailed analysis and documentation. This is invaluable for studying electromagnetic environments, tracking changes in specific locations, or building a record of measurements for research or investigation purposes.

Use Ultimate EMF Detector Free to explore the invisible electromagnetic world around you—from Earth's natural geomagnetic field to the fields generated by everyday electronics, power transformers, and metallic objects. The app works as a metal detector, device locator, and electromagnetic field analyzer all in one. Some users even report using it to investigate unusual electromagnetic anomalies, though electromagnetic sensitivity remains a topic of ongoing scientific discussion.

The simple, user-friendly theme makes getting started easy for beginners, while advanced themes provide greater precision, customization options, and visual skins for experienced users. Choose your preferred detector appearance and measurement display style.

IMPORTANT: This app requires your phone to have a built-in magnetic sensor (magnetometer). If your device lacks this sensor or readings show zero, the app cannot function on your device. Use responsibly and avoid exposing your phone to powerful electrical devices like high-voltage transformers, as this may cause hardware damage.
