Magnetic Field & DC Current Detector
Features:
-----------------
- Precise measurement of the magnetic field strength
- Localizing of spots with electric current flowing
- Point measurements or line scan
- Measure x-, y- and z- direction of the magnetic field
- Haptic feedback for precise and "blind" localization
- Share your measurements as image or data
Short description
-----------------------------
With the magnetic field & DC current detector, you can easily and elegantly examine the origin and strength of a magnetic field. Use line scans to investigate areas more accurate. Share your measurements as pictures or data file for yourself or your friends for interpretation.
The origin of a magnetic field is connected to high DC currents. For example, you can quickly and easily determine the location of a power supply, a large consumer, or a defective part within a device. With the haptic feedback, you can even do this without having to look at the screen. For a later evaluation, share your measurement data.
Application scenarios (examples)

The magnetic field strength is detected with a sampling rate of 5 ms and an average of 50 ms. The accuracy is ~ 0.15 μT. In order to obtain quantitatively correct values for the magnetic fields, please calibrate the magnetic field sensor before application. You calibrate the sensor by moving the mobile phone in a loop and rotating around itself. Important: In a space where only the earth's magnetic field is present.
Alternating currents cannot be detected. For this, we are developing another app.
SMF APPS GbR accepts no liability whatsoever. The results obtained are an orientation value.

The SMF APPS GbR has set itself the task to develop helpful and innovative apps based on scientific knowledge.

DO NOT TRUST THIS APP, GET A REAL EMF DETECTOR AND MULTIMETER!! this app is complete bogus. Anyone with half a brain can see this, for those who know nothing of electrical current or how this app is actually working then you shouldn't be using it at all. it's a gag. micro Tesla reading can be manipulated by turning your phone, the all is using the compass, just not for measuring, its using it to change the value of the unit by the direction it finds itself. figured this out in 3 minutes of use.
Thought it was cool until I discovered that the reading was half influenced by the angle of the accelerometer. I could hold the phone upside and get high readings and upright for lower readings.
works great. uses compass for emf field. on my phone it's located in to top area which explain why the value changes when moving phone. not sure on accuracy. just tells me there is a current there. for a free app I gave it a 5 rating.
Very fun to play with. I find myself looking for the small, accidental electric currents caused by things like a metal Lamppost that is half in the Sun and half in the shade. this would be a good educational tool for someone just learning how these things work.
This is awesome. For anyone who loves to play Mad Scientist, or just wants to know what the characteristics of different objects or instances so you can draw your own story or comprehensiveness, then this is the app to have or add to the collection. IFLS!
Really accurate and made me discover High EMF in my house where I wouldnt have had a clue otherwise. I still want to know why the wall behind my dresser spikes dramatically like it does if i have it directed at my PC. Interesting.
Worked perfectly for 2 minutes. I was amazed. Then it wouldn't stop haptic feedback however I adjusted the sensitivity. Had to uninstall it. Sad because it look really good
Really usefull app. :) I was going to see some friends via subway and i just found out that there is a high magnetic field occuring when the train accelerates and stops :)
Loved it. It uses the magnetic sensor in the phone. If your phone says it has a compass then this app will work. I have a pretty powerful sub in my flat that makes this app go bonkers if I take it close to it. Haha
Wow great job developer! I love the adjustable trigger sensitivity for the vibration. Also you can zoom in on the graph while it's running and set markers while scrolling
Compared 2 others. MF&DC are easy to use. Accurate, Best one I've found. Try it and see for yourself. Excellent app.Good job on this one.Thnx for very efficient and useful app.
Nice g.u.i.[graphical user interface, ie:EYE CANDY;-] me lads. Backend seems nice too. Perfection is apk's that dont blind you with ads. Correct, NO ADS PPL!!! SAY NO MORE. DL NOW PEEPS. NOW I SAY!:-)
It definitely detects magnetic fields, but not for EFM detection; at least not accurately. I have still to figure out how to use this for DC voltage detection.
The dc current locator works very well even on the cheapest phone I've ever owned. I will have to research what an electromagmetic field is to check out that aspect of the app.
Absolutely amazing app! Works perfectly. Helped to figure out abnormal behaviour of the phone in the magnetic stand, where field topped 1400 something.
It's great. Even has the flashlight switch which, I am guessing, would be great for looking for things in the dark.
I build and race electric rc and this is a handy tool tuning tool. it lets me see the internals of a dc motor with having to remove it and tear it down for a visual inspection. Great tool to have in my tuning arsenal.
simple and effective, ads are not intrusive (so far) in its operation. Better than some paid options.
Great for watchmakers and watch enthusiasts! I use this in combination with a regular compass to analyze for stray magnetization of my watch components.
Simply magnificent ❣️ best you can get AND for free! Better than an actual meter I bought on Amazon. To top it all you can export the data.
easy and accurate. It needs an add on ext file for storing, and labeled device reading, and setting
A man. I like how the app is up and running and has a format with an explicate to function dedicated to needed simplicity. As someone whos mathematics strength are dwindiling in the graphic measure ment lack pppp ,;:'"*_ERROR CODE 404: *91 Phud. i love the flashlight shortcut. but its not _"NEW"*!?- How can we fix that?!.
Simple to use.... is quite useful for locating energy fluctuating (thus energy loss) in 115 & 220 volt systems...
Just learning how to use it and will read some more online on magnetic fields, but amazed to it changingbvalues on old phones new phones and other WiFi and electronic devices
needs a help tab. explain your readings and options to a non teck. very good for a beginner...
Very interesting, I've read from CA research that sustained exposure to micro Tesla's over 100 is cancerous. I've tested everywhere and it's mostly normal readings. But If you pass this App sensor over another cell phone within two inches the reading can go over 800mT.
