Stud finder

Sweep the wall

Idle

Hold the phone flat against the wall, stay still for the calibration, then slide slowly sideways. The reading rises as you cross a drywall screw.

Screws found this sweep: 0

Distance from the corner to the first stud you found (inches)

Enter one confirmed stud and we'll mark the rest of the wall.

· Remove your phone case and any magnetic wallet for accurate readings.

· Keep the phone at the same angle while you slide — rotation moves the compass too.

· Screws sit in a straight vertical line — confirm two before you drill.

· Interior walls are usually 16" on center; some older exterior walls run 24".
