Stop guessing where to drill. Stud Finder Plus turns your iPhone into a magnetic stud detector — scan your wall and see real-time signal feedback in seconds. No stud finder tool needed.

Real-time magnetic detection, adjustable sensitivity, and a clear visual gauge — all from your iPhone.
Scan along your wall and get real-time magnetic signal feedback. The app detects metal fasteners behind drywall instantly — no waiting, no guessing.
Watch the needle move as you approach a stud. The color-coded gauge shifts from green to red so you know exactly when you're on target.
When the magnetic signal is strong enough, a bold METAL SIGNAL indicator appears. No ambiguity — you know precisely where the stud is.
Thick plaster? Thin drywall? Adjust the sensitivity to match your wall type and get accurate readings every time.
Calibrate against your specific wall for a rock-solid baseline. Eliminates false positives and gives you readings you can trust.
Your iPhone's built-in magnetometer does the work. No need to buy a separate stud finder tool — just download and scan.
Hold your iPhone flat against the wall in an empty area and tap calibrate to set your baseline.
Slowly slide your phone along the wall. Watch the gauge respond in real time as you approach metal.
When the METAL SIGNAL indicator fires, mark the spot. You've found your stud.

A clean, focused interface built for one thing: finding studs fast.
Whether you're mounting a TV, hanging art, or installing shelves — Stud Finder Plus has you covered.
Find the studs behind your drywall so your TV bracket anchors into solid wood — not just drywall anchors that can fail under weight.
Floating shelves, mirrors, and large frames need stud support. Scan, mark, and mount with confidence.
Locate framing before cutting into walls, running wires, or installing cabinets. Know what's behind the drywall before you start.
Anchor bookshelves, dressers, and heavy furniture to wall studs to prevent tip-overs. A stud finder is essential for child safety.
