## What is Wall Stud Magnetic Detector?

Use Your Device to Detect Studs and Magnetic Fields. Quickly detect wood studs hidden under walls, drywall, plasterboard, or stucco.

Wall Stud Magnetic Detector uses your device's compass (magnetometer) sensor to precisely pinpoint metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs. 

This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the needle will move and a beep can be heard.

The compass sensor detects subtle changes in the background magnetic fields caused by the conductive metal fasteners that are located in all wooden studs. 

Features:
- Automatic sensor that measures the magnetic field in uT.
- Active detection beep.
- You can store the time when the stud is detected.

There is also a quick video tutorial that shows how the app works: https://www.youtube.com/embed/gTQHwS7XwXk?rel=0

Happy construction.

### 4/5 — New to App

*2024-01-30*

So far it appears the app may do what it states. I cannot give further info as the app requires a review rather quickly after first getting the app.
To comply with review requirement to maintain the app as free, the review is needed. So to be fair to the developer and to individual reader lookin at the review, I am submitting this. It appears to work but I haven’t used it enough to really say how well it really works.  Once I use it numerous times I will give a better or worse review as appropriate.

*2022-11-18*

I downloaded this app to be able to find the studs in my wall so that I can rehang my fish that i have mounted. So far this seems to be the best app for the job.
