Stud Finder vs Stud Finder Plus

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.

# Stud Finder App Description **Find likely mounting zones with confidence, not guesswork.** Stud Finder uses your iPhone's built-in magnetometer to measure magnetic field changes that may indicate magnetic metal behind drywall. It provides live signal estimates to help you identify possible wall mounting areas. No extra hardware required. Open the app, calibrate on a low-signal area, then scan slowly along the wall while monitoring real-time feedback. Built for everyday DIY tasks like mounting TVs, shelves, mirrors, and frames. Performance varies based on wall material, phone model, phone case, and nearby interference. ## Features - Real-time 270-degree magnetic signal gauge with color-based intensity - Clear **METAL SIGNAL** indicator at higher signal levels - Adjustable sensitivity for different wall conditions - Manual calibration for a more stable baseline - Audio tone feedback that changes with signal intensity - Haptic feedback that scales with signal strength - 30-second signal history graph to help verify peaks - Built-in onboarding and practical scanning tips - Offline use, with no additional hardware ## Common Use Cases - Locate likely anchor points before mounting a TV bracket - Plan shelf or cabinet placement - Hang mirrors, art, and picture frames - Check spacing patterns during layout planning - Re-scan and confirm areas during installation ## How It Works Stud Finder measures changes in magnetic fields and highlights likely signal peaks behind the wall surface. It detects magnetic metal signals only. It does **not** detect wood studs directly and does not guarantee stud location. ## Important Safety Notice Stud Finder is **not** a safety device. It cannot detect electrical wiring, plumbing, or gas lines and must not be used for safety-critical decisions. Always verify with additional tools and methods before drilling, cutting, or mounting.
