STUD FINDER – WALL SCAN Find studs and metal behind walls using your Phone’s built-in sensors. Stud Finder – Wall Scan turns your Phone into a simple, reliable wall-scanning tool. Scan walls in real time to locate metal fasteners commonly found in wooden studs, helping you drill and mount with more confidence. Designed for DIY projects, home mounting, and everyday use — no extra tools required. HOW IT WORKS Stud Finder uses your Phone’s built-in sensors to detect magnetic anomalies behind walls. These anomalies often come from steel nails or screws used to secure wooden studs, as well as some metal pipes or conduits. As you move your phone slowly across the wall, the app provides live visual, audio, and haptic feedback to guide you toward areas of stronger magnetic signal. KEY FEATURES • Real-time wall scanning • Live magnetic strength meter • Edge and center guidance for detected objects • Audio and haptic feedback while scanning • Adjustable sensitivity • Simple calibration for better results • Scan history saved locally • Export readings as CSV • Clean, distraction-free interface USE CASES • Mount TVs, shelves, and cabinets • Locate stud areas before drilling • Reduce guesswork behind walls • DIY and home improvement projects STUD FINDER PRO Stud Finder Pro is required to use the app. Choose a one-time Lifetime purchase or a 24-hour pass — no subscription. Pro includes live scanning, full 30x sensitivity, detection history with CSV export, and the bubble level. IMPORTANT LIMITATIONS (PLEASE READ) Stud Finder is designed to assist — not replace — professional tools. • Detects ferromagnetic metals only (such as steel nails and screws) • Cannot reliably detect wooden studs without metal fasteners • Does not safely or reliably detect live electrical wiring • Accuracy depends on wall thickness, phone model, movement speed, and nearby interference • Results improve with slow, steady scanning and proper calibration Always follow standard safety practices when drilling. TIPS FOR BEST RESULTS • Move your phone slowly and steadily • Calibrate before scanning • Avoid nearby metal objects or electronics • Scan the same area multiple times for confirmation PRIVACY All scans and data stay on your device.
