Turn your iPhone into a wall scanner before you drill.
Stud Finder Pro is a stud finder app, wall scanner, metal detector, and drilling toolbox for homeowners, renters, DIY builders, contractors, installers, and anyone who needs a safer way to check a wall before making a hole. Use your iPhone to scan for studs, hidden metal, pipes, wires, rebar, and fasteners, then plan the right anchor, screw, drill bit, and level setup for the job.
