We are encouraging people to place magnets around and on electronics because why???

Works better than I expected. People have no clue what they are talking about . . . "encouraging people to put magnets around electronics". All electronic devices with a current (ie on) produce an EM field. Learn some physics folks. This is a really cool app.

This is an excellent app, doing everything that is advertised. The arrows give a clear view of the direction of the magnetic field and the acceleration. They are a lot easier to visualize with this than by looking at the raw sensor numbers. I especially like the magnetic declination view. This is useful for learning about magnetism as well as seeing what kinds of fields are emitted by various devices around the house.

Great app I could measure the magnetic field of my new rewound coil on my older outboard engine ??

I love the 3D visualization of the sensors. It would be cool if it included the gyro data as well as logging. It could be useful for science experiments.

Work well on my 4S. I would suggest not getting strong magnets near the phone. It will not hurt the electronics, but it could make the phone frame slightly magnetic and interfere with the compass.
