This app DOES move the needle on the uT gauge when a specific part of your phone gets CLOSE to metal. NOTE: This app appears to be more sensitive to nearby metal if you take your iPhone out of its case (my Mophie case impedes sensitivity). However, the metal must be VERY close to a specific area of the back of my iPhone in order to get a decent response from the meter. For some inexplicable reason, the app displays a running graph display of the x, y, and z values of the ACCELEROMETERS during sensing. I would have preferred to have NO accelerometer data displayed and instead see a running graph of micro-Tesla field strength over time. Also, there appears to be no sensitivity setting nor is there a BEEP from the BASE METAL DETECTOR app to when the uT fluctuates indicating nearby metal. Each of the above missing features are worth an additional star each. If those features are added, I wall award stars accordingly.
Penned the most EXTRAORDINARILY SPECTACULAR review, in the entire history of app reviews. Just as I typed the last word of this masterpiece the App Store suddenly deleted it. (They’ve actually done this to me a few times before.) Sorry. My rating and review for the Apple App Store? Zero stars. No review.
There was a comment about accelerometer output displayed on the graph, this is not correct or possible. The graph shows steady state offsets. There is no steady acceleration, these are magnetic field vectors. Notes say that sound and sensitivity are adjustable, I cannot find this functionality.
The Best Metal Detector is an application intended for entertainment purposes only. It detects the presence of metal nearby by measuring the magnetic field value. This useful instrument uses the magnetic sensor built-in your mobile device and shows magnetic field level in μT (microtesla). The Best Metal Detector allows to identify metal object in close area, because all metals generate magnetic field which strength can be measured with this tool. Usage is quite simple: launch this application on your mobile device and move it around. You will see that the magnetic field level shown on screen is constantly fluctuating. Colorful lines represent the three dimensions and the numbers on top shows the value of magnetic field level (EMF). The chart will increase and the device will vibrate and makes sounds announcing that metal is close. In settings you can change the sensitivity of vibration and sound effects.
