iPhone

Detect metal studs, pipes, and wiring behind walls using your iPhone magnetometer. Vibration feedback and scan timeline included. Now with Kalman filter precision. Find metal studs, pipes, and hidden wiring behind walls instantly. Stud Finder uses your iPhone's magnetometer to scan drywall and locate metal objects — essential for hanging shelves, TVs, and home renovation projects. REAL-TIME MAGNETIC FIELD DETECTION The app continuously monitors magnetic field changes as you move your phone along the wall. When metal is detected, you'll see an immediate spike in the reading. VIBRATION & SOUND FEEDBACK Feel a vibration and hear an alert when the sensor detects metal behind the wall. Hands-free detection lets you focus on marking the spot. SCAN TIMELINE View a visual timeline of your scan showing exactly where magnetic field changes occurred. Identify stud spacing patterns at a glance. CALIBRATION One-tap calibration ensures accurate readings by accounting for your environment's baseline magnetic field. SENSITIVITY PRESETS Choose from Low, Medium, and High sensitivity presets to match different wall thicknesses and materials. WALL MATERIAL PRESETS Select your wall type — drywall, plaster, brick, or concrete — for optimized detection algorithms. Perfect for DIY homeowners hanging shelves or TVs, contractors locating studs before drilling, and electricians tracing wiring paths. No additional hardware required. Your iPhone's magnetometer does all the work.
