Metal Detector is a free iPhone app developed by Mindateq Sp. z o.o. It falls under the category of Utilities & Tools and offers a range of features to assist users in finding metal objects nearby.

The main functionality of Metal Detector is its ability to detect metal objects by measuring the magnetic field level. This can be particularly useful for finding lost keys, coins, or even wires in walls. The app utilizes the magnetic sensor built into your smartphone to detect magnetic metals such as iron, nickel, steel, and alloys. However, it should be noted that the app will not detect silver, gold, and copper coins as they do not have a magnetic field.

In addition to the metal detecting feature, Metal Detector also includes a set of basic tools. These tools include a virtual tape measure, ruler, protractor, and level tool. This makes the app a handy companion for various measurement tasks.

Overall, Metal Detector - Stud Finder is a versatile app that offers both metal detection and basic measurement tools. Whether you're searching for lost objects or need to take measurements, this app provides a convenient solution.
