Stud Finder App
Wall Scanner
Before you drill, know what's behind the wall.
01
Two Scan Modes
Stud Mode — Tuned for the faint, brief signals produced by the nails and screws fastening a stud to the wall. Trace the fastener line to locate the stud edge. Metal Mode — Tuned for the strong, sustained fields of pipes, rebar, conduit and steel studs. The threshold sits high enough that a nail line won't trigger it, so you can tell a fastener from a pipe.
02
Features
- One-tap calibration against your actual wall, so readings adapt to the room
- Live signal gauge with real-time strength readout in microtesla
- Haptic feedback the moment a hit is detected
- Save scans with a label like "Living room wall" and revisit them anytime
- Keep-screen-awake option so the display won't sleep mid-sweep

How It Works — And What It Can't Do
We think you should know exactly what you're buying. Your phone's magnetometer senses magnetic fields. That means it detects ferrous metal — steel nails, screws, pipes, rebar and conduit. Wood is not magnetic, so no phone can detect wood directly. Stud Finder locates studs the same way a magnetic stud finder does: by finding the metal fasteners holding them in place.
