Wall Stud Finder & Scanner Downloads & RevenueWall Stud Finder & Scanner · App Store

Your phone already has the sensor a magnetic stud finder uses. StudSignal turns it into a responsive wall scanner: slide the phone across the wall and watch the live trace react to the screws and nails hiding behind it.

A CLEAR SIGNAL, NOT A GUESS
- A wide live gauge shows relative magnetic strength as you scan
- The trace line draws every bump, so you can compare peaks at a glance
- Strong signals fire haptics and an optional tone — no need to watch the screen while your hand is on the wall

CALIBRATED TO YOUR WALL
- One-second calibration on a bare patch sets the baseline
- The threshold adapts to your environment's noise automatically
- Three sensitivity levels for plaster, drywall, and busy environments

KEEP WHAT YOU FOUND
- Save any scan with a label — "living room north wall" — and revisit the full trace and every peak later
- All data stays on your phone

StudSignal shows the relative magnetic response of metal fasteners. It cannot detect live wiring or wood itself — always verify with dedicated tools before drilling. No ads, no subscription: one purchase, forever.
