Description

A free tool for detecting, measuring and recording magnetic fields and metal objects!

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. Since the app can be used to measure the presence of metallic objects as well as electromagnetic fields, it is a handy little tool for both experiments and research.

You can either use it for real-time scanning, or automatically record the measurements for a longer period of time, and then analyze the results at a later time.

If your device doesn't have a magnetometer sensor, you can activate the "Simulated Mode" from the settings screen, to see it in action.

Features
* Easy to use detection of Metallic objects and Electromagnetic fields
* Real and accurate measurements using the magnetometer sensor of your device
* Automated recording for long-time measurements
* View and analyze recorded data from within the app
* Optional sound feedback signal
* The provided measurements are in micro Tesla units (µT).
* Gauge showing real-time strength (magnitude) of the electromagnetic field
* Diagram showing real-time measurement of electromagnetic field strength in three dimensions (x, y, z)
* Clean and Responsive UI supporting both iPad and iPhone

Support
For support and feedback, email us, visit our support site or use the in-app buttons on the Settings screen.

Usage
* The app provides measurements in micro Tesla (µT) units. 1 µT = 10 mG (milli gauss).
* The Earths magnetic field ranges from 25 to 65 micro Tesla, depending on your location.
* Test the scanner by holding your phone near devices and materials that emanate electromagnetic fields.
* The automated Recording feature allows you to run the app in the background for a longer period of time, in order to measure the electromagnetic fields that you are exposed to during that time. The results are saved and can then be analyzed using touch and swipe gesture enabled charts directly from within the app. All results are saved as standard CSV files and can be opened in other apps and applications supporting this common file format.

Upgrades
This free app is fully usable as is, but you can visit the Store screen and upgrade the app with additional useful features.



We've worked hard to make this free app as good as possible, and hope that you will find it both entertaining and useful. Constructive feedback and reviews are always appreciated since it is your opinion that drives future development of the app.

Thanks for downloading!




Disclaimer
No app can fully replace the special purpose devices that measure electromagnetic fields or detect metallic objects. 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.

Working well

I will be using this app to teach a science lesson. I will give students magnets of different strength and a ruler and leave it to them to create and answer their questions. The app itself works reliably on my iPad and iPhone. Any issues may be due to the device used and not the app.

Finding wireless antennas on devices

I use the app to locate the wifi antennas on my devices (cell phones, iPad, computer etc). Then I can avoid putting that area near my body. I find it by scanning with my phone around a device and when the needle goes to red that’s the antenna giving out and picking up it’s dangerous level of wifi. I especially want children to see how certain areas of a device are important to keep at a distance. I also use interventions to reduce the level of dangerous emf such as pendants with coiled copy(counterclockwise) and high-quality obsidian, in addition to crystal in a resin. Yes they truly work if you have one correctly made. I have tested it by putting the pendant next to the antenna and the needle drops to low yellow or green. I also check for cell towers nearby.

Did the job

I needed a quick tool to locate a 8" diameter round steel vault cover under 2" of packed gravel and dirt. The app did the job once I figured out how close (very) to hold my phone to the ground. I looked like an idiot on my hands and knees on the side of the road, but I found the vault and got the job done.
