Detect studs, screws, nails, and measure magnetic fields (EMF) instantly with your iPhone. Two powerful modes in one app: Stud Finder & Magnetometer — works entirely on your iPhone. Perfect for DIY enthusiasts, home improvement projects, tech experiments, educational purposes, contractors, engineers, and anyone curious about magnetic fields or hidden metal. Stud Finder Mode Locate wall studs, screws, nails, metal pipes, and hidden metal objects behind drywall, plaster, and panel walls. Accurate readings using your iPhone's built-in magnetic sensor. Pro Tip: Hold the bottom third of the back near the wall — that's where the sensor is. Pause scans to note field values. Re-zero the sensor anytime for accurate readings. Ideal for hanging shelves, picture frames, cabinets, mirrors, or TVs without guesswork. Magnetometer Mode (EMF Detection) Measure magnetic fields in real time with a live graph. Detect EMF levels, metal objects, and magnetic anomalies. Perfect for students, engineers, hobbyists, STEM labs, and science fairs. Level Finder Mode (New in 2.1) Turn your iPhone into a precision spirit level — no extra hardware needed. Place your phone flat on a surface or hold it upright against a wall edge to measure tilt in real time. Locks with haptic feedback and a gentle audio tone the instant you hit perfect horizontal. Rotate to landscape for a full-screen gauge with a large degree readout. Ideal for hanging shelves, mirrors, TVs, tile work, carpentry, and furniture assembly. Three-in-One Functionality Find studs, detect magnetic fields (EMF), and level surfaces — all from one app. Perfect for home DIY, construction, school labs, STEM experiments, or curiosity-driven exploration. Provides actionable, real-time feedback for home improvement and tech applications. Why Users Love Stud + Metal Scanner Clean interface for scanning walls or visualizing magnetic fields.
