Stud Finder Wall Scan Magnet

Slide your phone along the wall and watch the trace light up over hidden screws and nails. Calibrated, logged, and yours forever — no ads, no subscription.

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.
