Transform your iPhone into a precision metal-detection toolkit with Stud Finder - AI EMF Detector. Whether you're a DIY enthusiast, a professional tradesperson, or simply curious about what’s hiding behind your walls, this app gives you powerful features to explore your space in a completely new way. ---Key Features Automatic EMF Sensor Calibration: On first launch the app calibrates itself using your phone’s magnetometer, so you’re ready to go without fuss. Real-Time Histogram Display: See live magnetic field changes in a graph as you scan surfaces—detect subtle variations and track your progress visually. Sound & Vibration Alerts: The closer you get to a metal object or embedded item, the stronger the audio beep and vibration feedback. You’ll feel when something’s there. Built-in Bubble Level: Use the spirit-level tool to ensure your device is aligned perfectly before scanning—ideal for straight-edge installations or wall projects. Guided Sensor Location Instructions: Not sure where your phone’s sensor is? We’ve got you. Step-by-step instructions point out where the magnetometer sits so you can hold the device correctly. ---What You Can Do Scan walls for studs, nails, or screws during installation of shelving, flatscreen TVs, or cabinets. Search for hidden metal pipes or wiring behind drywall with confidence. Use it for hobby or treasure-hunt style exploration of magnetic surfaces. Mark and monitor fluctuating EMF levels in any room or space—track real-time changes via the histogram. ---Please Note The app relies on your device’s built-in magnetometer. If your phone lacks a magnetic sensor, the detection capabilities will be limited. It works best for ferrous (magnetic) metals like steel and iron. Non-ferrous metals (like gold or copper) may not generate a detectable magnetic field. Environmental electromagnetic interference (wires, other electronic devices) can affect accuracy. Use proper scanning technique for best results. ---Why choose Stud Finder - AI EMF Detector? Because it combines ease-of-use with advanced sensing and feedback: you get calibration, visual graphs, sound/vibration cues and leveling—all in one compact tool. No separate device required, just your iPhone and your curiosity. Download Stud Finder - AI EMF Detector now, and uncover what’s hidden beneath the surface.
