## What is Stud Finder App?

Before you drill, know what's behind the wall.

Stud Finder uses your phone's built-in magnetometer to detect metal hidden in
your walls — the nails and screws that mark a stud's edge, and the pipes,
rebar and conduit you want to avoid hitting.

Calibrate against a clean section of wall, then sweep slowly. The live gauge
rises as you approach a target and calls a hit when the signal is strong
enough.


TWO SCAN MODES

Stud Mode — Tuned for the faint, brief signals produced by the nails and
screws fastening a stud to the wall. Trace the fastener line to locate the
stud edge.

Metal Mode — Tuned for the strong, sustained fields of pipes, rebar, conduit
and steel studs. The threshold sits high enough that a nail line won't
trigger it, so you can tell a fastener from a pipe.

Both modes are free. No paywall on the core detector.


FEATURES

• One-tap calibration against your actual wall, so readings adapt to the room
• Live signal gauge with real-time strength readout in microtesla
• Haptic feedback the moment a hit is detected
• Save scans with a label like "Living room wall" and revisit them anytime
• Keep-screen-awake option so the display won't sleep mid-sweep
• Optional reminder if you haven't scanned in a while
• Light and dark themes


STUD FINDER PRO

• Deep Scan — boosted sensitivity that surfaces faint fastener lines a
  standard scan can miss
• Unlimited saved scans (the free version keeps your 5 most recent)


HOW IT WORKS — AND WHAT IT CAN'T DO

We think you should know exactly what you're buying.

Your phone's magnetometer senses magnetic fields. That means it detects
ferrous metal — steel nails, screws, pipes, rebar and conduit. Wood is not
magnetic, so no phone can detect wood directly. Stud Finder locates studs the
same way a magnetic stud finder does: by finding the metal fasteners holding
them in place.

This is why we describe what we find by signal strength rather than claiming
to identify materials. If a reading in Stud Mode is unusually strong, the app
tells you it's likely metal rather than a stud.

Results depend on your device's magnetometer, wall material and depth.
Detection is less reliable through thick plaster, tile, concrete or metal
lath. Always verify before drilling, and never rely on any app alone when
electrical wiring or plumbing may be present.


PRIVACY

Stud Finder is designed with your privacy in mind and does not share personal
data unnecessarily. Your scans are stored on your device.

### 4/5 — Works surprisingly well

*2026-08-29*

Had no idea a phone could do this but this app worked surprisingly well. I still don’t think it’s as accurate as a dedicated stud finder device but it works in a pinch. Was able to locate close enough to a stud and get the job done

### 5/5 — Amazing

*2026-08-23*

Stud Finder is a really helpful app for DIY projects and home repairs. 🔧 I’d use it before drilling to scan the wall for metal fasteners, pipes, rebar, or conduit. The live gauge, haptic alerts, calibration, and two scan modes make it easy to use. It also stores scans locally, so your results stay on your phone.

**Developer response:** Thank you very much

### 5/5 — It works

*2026-08-18*

Got it for free. Just in time where i needed it. Must calibrate first at free wall. Right now redeem code for Pro til 19.08.2026: STUDFINDER

**Developer response:** Thank you very much for this positive review

## Frequently asked questions about Stud Finder App

### How does Stud Finder App work?

Stud Finder App uses your phone's built-in magnetometer to detect ferrous metals like nails, screws, pipes, and rebar within walls. It finds studs by locating the metal fasteners holding them in place.

### What are the two scan modes in Stud Finder App?

Stud Mode is tuned for faint signals from nails and screws marking stud edges, while Metal Mode detects stronger fields from pipes, rebar, and steel studs. Both are free to use.

### Does Stud Finder App have ads?

Yes, Stud Finder App contains advertisements. This is common for free utility applications that offer in-app purchases for premium features.

### What is Stud Finder Pro?

Stud Finder Pro is an in-app purchase that offers a 'Deep Scan' mode for boosted sensitivity to find faint fastener lines, and unlimited saved scans, compared to the free version's limit of 5.

### Can Stud Finder App detect wood studs directly?

No, wood is not magnetic, so no phone can detect wood directly. Stud Finder App locates studs by finding the metal fasteners holding them in place.

### What are the limitations of Stud Finder App?
