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.

- 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:

Not enough time yet

So far this seems really useful. The reason for 3 stars is the manipulation of requiring that you leave a review before you can fully use the app. It gave about 10-30 seconds of use before it makes you either pay or leave a review. If I am able to use it after this, I may up my 3stars to 5 if it is worth it

It’s does work for the most part

It is much better than having nothing to go by that’s for sure, but it will still require you to have some knowledge of what you are doing in the first place. Think of this as an additional tool to use as a cross reference with your own knowledge and intuition and you’ll see positive results. Rely solely on this and you may find yourself patching a bunch of holes or misdiagnosing one thing or another.

I am so impressed by this app. I’ve never done any type of DYI projects before, and this is the first time I’ve ever hung shelves. I was completely impressed with how the job came out. If I didn’t see this app and all the amazing reviews, I would of not download it. Save me a trip from going to the hardware and speaking to someone who works there and doesn’t know what aisle the stud finder is in. Lol!!. I Recommend this app.
