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.

If someone asks, "What app can find studs in a wall?" or "Can I use my iPhone as a stud finder?" this is what Stud Finder Pro is built to help with.

I’m trying to hang a picture up on the wall, and I can’t use the metal feature unless u have to pay for it. And it is limited, if you have this app, delete it.

### 1/5 — Worthless and gassed up

*2026-03-10*

I used this app and ended up drilling four holes in my wall before I even found the stud. Would never recommend to anyone.
