Initial release.
Find hidden nails, screws & pipes in walls with your phone's magnetic sensor.
MetalScope turns your phone into a handheld magnetometer for finding hidden ferrous metal - the iron and steel nails, screws, brackets, and pipes hiding behind your drywall, floor, or ceiling. No extra hardware, no permissions to grant. Just open the app, sweep the surface, and watch the dial react. WHAT IT DOES MetalScope reads your phone's built-in magnetic sensor and translates tiny shifts in the magnetic field into a clear, real-time signal. A 270-degree gauge sweeps toward the source as you get closer, a live scan chart traces the strength of every pass, and audio feedback (adjustable beeps that quicken and rise in pitch) lets you keep your eyes on the wall instead of the screen. Haptic pulses back up the sound so you can work in a noisy room and still feel the hit. BUILT FOR REAL JOBS - Locate the nail or screw holding a stud before you drill, so you don't hit it by accident - Sweep a wall before hanging a shelf, TV mount, or picture rail to avoid old fasteners - Check a floor or baseboard for embedded hardware before renovation work - Scan a yard, garden bed, or beach patch for stray iron and steel objects - Save and review scans later from your history, complete with strength readouts SENSITIVITY AND CALIBRATION Dial sensitivity up in quiet, low-interference spots or down in busy environments full of appliances and wiring. A quick calibration step sets your baseline so the detector adapts to the room you're actually standing in, not a factory default. HONEST ABOUT THE PHYSICS MetalScope is a magnetometer, not an X-ray. It detects ferromagnetic metal only - iron and steel. Aluminum, copper, brass, and most stainless steel will not trigger a response, because they don't have a magnetic signature to read. It cannot see through a wall to show you exact depth, size, or shape, and it will not find a wooden stud on its own - only the metal fastener holding it in place. Treat every reading as a helpful clue, not a guarantee, and always confirm before drilling into a wall that might hide plumbing or electrical lines. FREQUENTLY ASKED QUESTIONS Q: Does MetalScope find gold, silver, or coins? A: No. Those metals aren't magnetic, so a magnetometer can't detect them. MetalScope is built for ferrous metal - iron and steel - not treasure hunting for precious metals. Q: Can it tell me exactly how deep a nail is? A: Not precisely. The signal gets stronger as you get closer, which helps you narrow down a location, but MetalScope can't report an exact depth or size the way a dedicated stud finder with radar can. Q: Does it need camera, location, or any other permission? A: No. MetalScope only uses your phone's built-in magnetometer, the same sensor your compass already relies on. There's nothing else to grant. Q: Will it work without an internet connection? A: Yes, completely offline. Detection, scanning, and history all run locally on your device. Q: Is this a replacement for a professional pipe or cable detector? A: No. Before drilling anywhere plumbing, gas, or electrical lines might run, use a proper utility locator or consult a professional. MetalScope is a helpful first pass, not a safety certification. BUILT WITH PRIVACY IN MIND MetalScope doesn't need your camera, your location, or your contacts to work - the magnetic sensor is all it uses. No account, no sign-up, no data collection tied to your scans. METALSCOPE PRO A one-time purchase removes all ads for good - no subscription, pay once and you're done. Everything else, including full detection, scan history, and calibration, is already included for every user.
