A smart, high-precision compass and metal detector for detecting metals and determining directions.

The metal detector is an essential tool in the "Examination Tools" suite.

Important Note: All metal detector apps rely on a magnetometer. If the app doesn't work, please ensure your device has one.

How does the app work?

The app measures the magnetic field strength to locate metals using your phone's built-in magnetometer. The normal magnetic field strength (EMF) in nature is approximately 49 mT (microtesla) or 490 mG (milligauss); where 1 mT = 10 mG. As the device approaches any metal, you will notice a significant increase in the magnetic field strength.

Uses of the app:

Metal finder: Detect lost coins or metal objects.

Household tasks: Locate electrical wiring behind walls or buried iron pipes.

Other uses:

Some people occasionally use it (recreationally) as a device to track "paranormal phenomena" due to its sensitivity to energy changes.

How to use it: It's very simple: Open the app and move your phone around the target area. You'll notice the numbers and indicators fluctuating as soon as you approach a metallic object. That's it!

Important Technical Notes
Accuracy: The accuracy of the results depends entirely on the quality of the sensor in your device. Interference: The sensor is affected by electronic equipment (such as TVs and computers) due to the electromagnetic waves they emit.
Malfunctions: If the app isn't working, it may mean that the sensor in your phone is faulty or missing.
How to Calibrate
If you feel the readings are inaccurate, calibrate the sensor by pointing your phone towards the sky and moving it in the air in the shape of the number 8 ($8) several times.

Dual North: Easily switch between true north and magnetic north.

Comprehensive Data: Displays magnetic field strength, latitude and longitude, and weather information.

Astronomical Times: Accurate display of sunrise and sunset times.

Display Modes: Supports night mode and dark screen mode to save battery life.

⚠️ Important Precautions for Accuracy:
Magnetic Sensor: For the app to function, your phone must have a magnetometer. If your device does not support this feature, the app will not work; this is due to your device's technical specifications and not a flaw in the app.

Avoid Interference: For accurate results, please keep your phone away from:

Metallic objects and machinery.

Sources of strong electromagnetic fields.

Phone cases containing magnets.

💡 Usage Tip:
For best performance, hold your phone flat (horizontally), just as you would a traditional compass.
