Find studs behind drywall using your iPhone's built-in magnetometer. This app detects metal fasteners (the screws and nails holding your drywall to wood studs) and helps you locate stud lines behind your wall. HOW IT WORKS Your drywall is screwed into wooden studs roughly every 16 inches. This app picks up those screws by reading changes in the magnetic field as you sweep your phone across the wall. Find screws in a vertical line and you've found the stud. HOW TO USE Take your case off. Hold your phone flat against the wall. Sweep slowly left and right. When the signal spikes, there's metal nearby. Mark each spike, look for a vertical line of hits, and that's your stud. Drill a small pilot hole before you mount anything heavy. If the bit hits something solid, you're on the stud. If it punches right through, move an inch and try again. Takes 30 seconds. WHAT THIS APP CANNOT DO It detects metal, not wood. If there are no screws or nails in the wall where you're scanning, it won't find anything. It also won't work well through thick plaster, concrete, or tile. And it's not a replacement for a professional stud finder on structural work. For mounting a TV, hanging shelves, or putting up pictures on normal drywall, it works. No ads. No nag timers. No interruptions. PRIVACY No account. No tracking. No data leaves your phone.
