Stud Finder & Metal Detector

About this app

Find the screws and nails that hold drywall to the studs, check for metal pipes before you drill, and hang shelves straight. This app uses your phone's magnetometer, the sensor behind its compass, to turn it into a simple metal detector.

AN HONEST NOTE FIRST
Phones have no sensor that can see wood. This app finds METAL: steel screws and nails, iron pipes, rebar and magnets. Because drywall is screwed or nailed to the studs, finding a column of screws finds the stud. Copper, aluminium, plastic and wood don't show up.

METAL DETECTOR (FREE)
• Big live gauge with the magnetic field change in microtesla (µT), like a simple gauss meter
• Automatic zero, or precision calibration with Pro
• Sensitivity from 1 to 10 (Pro)
• Beeps faster and vibrates harder as you get closer
• Clear visual alert you can see across the room

STUD FINDER MODE
• Step-by-step guide: slide the phone flat along the wall
• Live scan trace that marks every screw or nail it passes (Pro)
• Tips on typical stud spacing (16 or 24 inches, 40 or 60 cm)

BUBBLE AND SPIRIT LEVEL (PRO)
• Lay it flat for a round bubble, or stand it on an edge for a bar level
• Angle to a tenth of a degree, with a tap when it is level

RULER (PRO)
• On-screen ruler in centimetres or inches
• Calibrate it once with any bank card for real-size accuracy

FREE AND PRO
The live metal detector, its gauge and its sound, vibration and visual alerts are free, with the stud-finding guide. Stud Finder Pro adds precision calibration that the app remembers, sensitivity from 1 to 10, the stud scan trace that marks every screw, the bubble level, the calibrated ruler and the sensor mode.
Pro is available as a weekly or yearly subscription (the yearly plan starts with a 3-day free trial) or a one-time lifetime purchase. Subscriptions renew automatically until cancelled; cancel anytime in your account settings at least 24 hours before the period ends.

PRIVATE BY DESIGN
No account, no ads and no tracking. Your readings never leave your phone. Purchases are checked through Adapty with an anonymous ID.

TIPS
• Calibrate with the phone at least 30 cm (1 ft) from metal, laptops and speakers.
• Remove magnetic phone cases and wallets; they swamp the sensor.
• The sensor is usually near the top of the phone. Lead with the top edge.
• Always check for live wires and pipes with the right tool before drilling. This app is a helper, not a guarantee.
