This App turn your device into a Magnetic Strength Meter (DC Gauss Meter). DC magnetic fields can develop in many steel or iron objects if they have been exposed to magnetic fields, current, or friction. This App detects residual magnetism in steel parts quickly and accurately. Simply place the device edge near or against the object being tested, to have a reading representing the magnetism in the object at that site as well as polarity. Will also possible to verify thoroughness of de-magnetizing. Check out your car, bed frame, desk furniture or any other metal objects you spend time with. Can also be used to check the strength of magnets. Features: - Detect the strength of Magnetic force fields on all three axis’s (x,y,z) - Switchable units: Tesla, Gauss - 1 mG (0.1μT) Resolution Applications: - Assessment of magnetic materials. - Analysis of magnetic circuits and components - Measurement of residual magnetis - Measure stray and leakage fields - Measurement of absolute, and differential fields - Testing, sorting, classifying magnets - DC and AC motor testing - Relay and solenoid test - Loudspeaker test Note: the measure is never 0 because there is the Earth's magnetic field

Verdict
The clearest difference is price: EMF Detector at Free against Magnetometer / Gaussmeter's $0.99. EMF Detector also leads on update cadence (every 2 weeks vs every 40 months) and ratings volume (319 vs 1). Magnetometer / Gaussmeter's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 3). On ads and device support there is nothing between them.
