Precision Stud & Screw Finder

Find likely steel screws, nails, metal studs, plates, and conduit behind drywall with a clear target score, color meter, and sensor-aligned bullseye.

Precision Stud & Screw Finder begins by helping you find the exact location of the magnetic sensor inside your phone. Because that sensor is usually near a corner—not the center of the phone—the app saves its position and places the bullseye directly over the actual sensing point.

BUILT FOR PRACTICAL USE

• Easy 0–10 target score
• Bright green, yellow, and red meter
• Bullseye positioned over your phone’s real sensor
• Center line for a likely wider metal area
• Wall-background baseline that filters normal magnetic noise
• Motion and rotation compensation to reduce false readings
• Haptic feedback for strong target readings
• Precision edge and surface level
• Large, readable controls and instructions

HOW IT WORKS

1. Find your phone’s sensor once using a stationary screw.
2. Hold the phone flat against the wall and set the wall background.
3. Move slowly across the wall.
4. Mark the wall behind the bullseye at the strongest repeatable reading.

You receive two complete scans free. Precision Pro adds unlimited scans and the built-in level with a one-time purchase. A 24-hour full-feature trial is also available and never automatically charges.

IMPORTANT

This app responds to nearby magnetic steel. It does not directly detect wood studs, copper, PVC, aluminum, or live electrical wires. Results vary by phone, case, wall material, target depth, and nearby magnetic interference. Remove magnetic cases or accessories, scan slowly, repeat from both directions, and always confirm before drilling.
