Find the Right Spot Before You Drill Stud Finder: Wall Detector Pro uses your iPhone's built-in magnetometer (magnetic sensor) to locate the screws and nails that hold drywall to the studs behind it. Find a line of fasteners and you have found the stud. HOW IT WORKS Your iPhone's magnetic sensor reacts to iron and steel. Slide the phone slowly across the wall: when it passes over a drywall screw, nail or other steel object, the reading jumps and the app alerts you. The app does not see wood, plastic or copper wiring directly — it finds the metal fasteners in the studs. WHAT'S INCLUDED Magnetic Metal Detection Live magnetic field strength in microtesla (μT) with a gauge that rises as you get closer to a screw or nail. (Premium subscription required) Sound & Haptic Alerts Hear a beep and feel a vibration the moment metal is detected, so you can keep your eyes on the wall. (Premium subscription required) Adjustable Sensitivity Tune the detection threshold to cut false alerts or to pick up fasteners that sit deeper in the wall. (Premium subscription required) Bubble Level — Free A spirit level for shelves, frames and trim that works in portrait, landscape and flat on a surface. No subscription needed. TIPS FOR BEST RESULTS - Remove magnetic cases and MagSafe accessories, and keep away from speakers and large metal objects. - Move slowly and keep the phone flat against the wall. - Mark each hit, then look for a vertical line of fasteners — that is your stud. - Studs are usually 16 in (40 cm) apart. Always double-check before drilling, especially near outlets and switches.
