Magnetometer X
Metal Detector & Stud Finder
Free · In‑App Purchases
Transform your iPhone or iPad into a precision magnetic field and metal detector. Magnetometer X uses your device's built-in sensor to measure electromagnetic fields in real time, helping you locate ferromagnetic metal objects, find studs behind walls, and explore the magnetic world around you.
THREE POWERFUL MODES
Gauge Mode (FREE)
A beautiful analog-style gauge displays magnetic field strength with instant visual feedback. Perfect for quick metal detection and general-purpose measurements.
Wall Scanner Mode (PRO)
A real-time scrolling graph helps you locate studs, steel pipes, and magnetic anomalies hidden behind drywall. Scan slowly across a wall and watch the graph spike when you pass over metal—no guesswork required.
Scientific Mode (PRO)
Built for students, researchers, and professionals who need deeper analysis:
• Visualization of magnetic 3D field vectors and polarity
• Separate X, Y, Z axis readings with total field magnitude
• Compare calibrated anomaly vs. total field
• Record data at 1 Hz, 10 Hz, or raw sensor rate (~100 Hz)
• Export GPS-tagged CSV logs for field research
KEY FEATURES
• Zero Calibration – Set a baseline anywhere to detect relative changes
• Multiple Units – Display readings in microtesla (μT), milligauss (mG), or gauss (G)
• Audio & Haptic Feedback – Three sound styles plus tactile vibrations help you detect without looking at the screen (haptic feedback is not available on iPad)
• Dark & Light Themes – Choose your preferred appearance
PRACTICAL USES
• Find wall studs before drilling
• Detect steel objects in walls, floors, or ceilings
• Identify magnetized tools
• Educational demonstrations of magnetic fields
• Paranormal investigation (EMF hunting)
• Science projects and physics experiments
NO SUBSCRIPTIONS
Unlock PRO features with a single one-time purchase. No recurring fees, no trials that expire—just full access forever.
IMPORTANT NOTE ON METALS: Magnetometer X detects ferrous (magnetic) metals like iron, steel, and nickel. It does not detect non-ferrous metals such as copper, aluminum, silver, or gold. If a pipe or stud is not magnetic, the sensor will not react to it.
