EMF Meter Free Utility for iPod, iPhone for iOS

The EMF Meter Free Utility transforms your iPhone into a sophisticated electromagnetic field tester. Utilizing the device's internal compass hardware, this app displays raw magnetic field data in real-time, making it a valuable tool for a variety of users, including scientists, engineers, and enthusiasts. Key features include the ability to record findings with a 'Readings Log', which can be shared via in-app email, enhancing its utility for educational and research purposes.

This application is designed for iPhone 3G(S) and iPhone 4 users and offers superior functionality compared to competing products. It measures magnetic field strength across three axes (x, y, z) in microteslas (µT). Users can pause readings for experiments and log them with time and date stamps. Version 2.2 adds location-saving features and mapping capabilities, developed in response to user feedback, while earlier updates introduced settings for reading calibration and alarms for specific thresholds.
