Some earthquake experts found that before a big earthquake comes, there might be a magnetic field disturbance. This app is able to keep monitoring the magnetic field variation and its location and give alarm if the magnetic field variation exceeds a threshold value. (Continued use of GPS running in the background can dramatically decrease battery life.)

Tesla Bot

Tesla Bot is a Geiger counter for magnetic fields, and plays synthesized Geiger counter-style clicks relative to the strength of a magnetic field, as measured by the built-in compass/magnetometer of your device. This synthesis model is accurate and scales well, providing authentic Geiger counter-like clicks (modeled after the CDV-700). (ie, they got too hot)

EMF Detector - Ultimate Magnetometer for You

FREE FOR LAST DAYGet It Now Understanding the sources of negative magnetic frequencies is a key component to an overall wellness plan EMF Detector is an instrument that measures the surrounding magnetic field in units of Gauss or Tesla. With it, you can: Take it close to your day-to-day basis, like televisions, computer, cell phones, alarm clocks, microwave ovens, and so on, the gauge will increase automatically. Use it as metal detectors: they can detect only magnetic metals, but can detect such metals at a much larger depth than conventional metal detectors.

Tesla - Metal detector and Magnetic field recorder

Detect, measure and record magnetic fields and metal objects An Electromagnetic Field is a physical field produced by electrically charged objects, including those which contain a high degree of iron (Fe) and therefore are considered as magnetic. This free app relies on the magnetometer sensor of your mobile device to transform your phone or tablet into a fun and easy to use metal detector / electromagnetic scanner. The reason that we cannot guarantee the accuracy of this app, is that the measurements are fully dependent on the hardware sensor provided by your mobile device.

Attenuator

Attenuator is a utility for anyone working with radio frequency sources and needs to know power and voltage after attenuation. You can specify an input voltage (Vpp or Vrms) and dB of attenuation to get the output voltage, power and attenuation. See the local barometric pressure, useful if the magnet boil-off is high

Magnetic Storms

Magnetic Storms is an app that shows in near real time the condition of the Earths magnetic field regarding the solar particle emissions. Three parameters are showed: the Kp index, based in an array of magnetic observatories around the Earth, the X-ray solar flares and the protons and electrons flux based in satellite observations. The layout was adjusted and now it works perfectly in iPhone4S, iPhone5 (all), iPhone6(s) and iPhone6(s) Plus, iPhone 7 and iPhone7 Plus, and iPad2, iPad Retina, iPad Air, iPad Pro and iPad Mini.
