About this app

Locate studs, nails, and screws behind your walls with precision. Stud Finder: Wall Scanner & Metal Detector transforms your smartphone into a practical DIY tool by utilizing your device’s built-in magnetic sensor to detect ferromagnetic metal hidden behind drywall.
Whether you are mounting a TV, hanging shelves, or installing cabinets, our app provides the real-time data you need to find the right spot to drill.

CORE FEATURES
• Live Camera Preview: Use your phone’s camera to overlay the scanning interface on your wall, helping you visualize the scanning process in real-time.
• Precision Metal Detection: Identifies the presence of nails and screws—the most reliable way to pinpoint the location of hidden wooden or metal studs.
• Dual Calibration Modes:
• Auto-Calibration: Automatically adapts to your environment for stable performance.
• On-Demand Calibration: Manually reset the sensor at any time to ensure maximum accuracy against different wall surfaces.
• Multi-Sensory Feedback: Get clear, immediate results through both sound alerts and haptic vibration patterns, allowing you to scan without needing to focus solely on the screen.
• Adjustable Sensitivity: Fine-tune the detection strength to suit different wall types and depths.

HOW TO USE
1. Calibrate: Hold your phone against the wall and initiate the calibration feature to establish a baseline.
2. Scan: Slowly glide your phone across the wall surface.
3. Detect: Follow the visual signal on the camera overlay, or listen for the intensifying audio and haptic feedback.
4. Mark: Once the signal peaks, you have located a metal fastener—the indicator of a stud.

IMPORTANT INFORMATION
• What we detect: This app detects magnetic metal (nails and screws). It does not detect wood, plastic/PEX pipes, or live electrical wires directly.
• Hardware requirements: This app requires your phone to have a functional built-in magnetometer (magnetic sensor).
• Usage tips: Always move your device slowly and keep it flush against the wall for the most accurate readings.
