The app is a radar detector for mobile devices. It works by using the device's built-in magnetometer to measure the magnetic field strength. The measured value is then used to detect the presence of metal objects, such as a car speedometer, which can generate a magnetic field.

The app works in a similar way to a radar gun. It measures the magnetic field and uses that information to detect objects. However, the app does not need to be pointed at the target. It can be used to measure the magnetic field in any direction.

The app can be used to measure the speed of objects, such as a car. It uses the device's built-in magnetometer to measure the magnetic field and uses that information to determine the speed of the car.

The app can be used to find the location of an object. It uses the device's built-in GPS to do this.
