Need to quickly detect wood studs hidden under drywall, plasterboard, or stucco in order to safely and securely hang a picture, shelf, TV or other wall fixture? Studfinder turns your mobile device into a stud detector tool! Studfinder uses your device's compass (magnetometer) sensor to precisely pinpoint metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs. A stud detector is essential for DIYs to securely hanging heavy wall fixtures and ensures the fasteners are well anchored in the solid wall studs hidden beneath the drywall.

This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the LED lights light up in sequence as your device's magnetometer approaches the stud. However, modern mobile devices do not have a density sensor (which is used in real studfinder tools), so Studfinder uses your compass (magnetometer) sensor instead. The compass sensor detects subtle changes in the background magnetic fields caused by the conductive metal fasteners that are located in all wooden studs. Because of the lack of a density sensor in mobile devices, studfinder apps cannot detect wood studs themselves, but instead, detect the metal fasteners in the studs. Please keep this difference in mind when using Studfinder.

- Automatic sensor check
- Active detection button
- Stability indicator (Green LED)
- 3 detection level indicators (Red LEDs)
- 10 sensitivity levels (for various drywall thicknesses)
- Toggle-able detection beeper
- Easy to follow, in-app DIY instructions

There is also a quick video tutorial that shows how the app works on my website: http://toadlybroodle.ca/portfolio/apps/stud-finder-app/

Thanks for downloading and using my app. I have constantly been updating and improving it since 2013, based on user feedback, in order to make it the most accurate, responsive, and easy to use stud finder app on the market. Please consider reviewing the app so future versions can be even further improved!

Wow not a single stud in my walls :)

Wow if I go by this stud finder I literally have 0 studs in my walls. I must have a magic house, ooooo man I’m going to make millions off this :)

No for real not a single stud came up on the app, said it worked off of metal in your walls from nails and what not so I moved my phone all over the wall up and down and all around but sadly nothing. Very happy I didn’t pay the (OMG ARE YOU KIDDING ME RIGHT NOW?????? $20!!!!!! Haha wow don’t wait your money people

They Must’ve updated the software! Legitimately works for me!

Tried the old fashioned way of finding the stud but after about 6 5/32 holes in my wall I decided to turn to an app and with nothing to lose I ignored the bad reviews and gave it a shot. Turns out it worked. Just turn the sensitivity all the way up, turn on the beeper and remember to point your camera at the wall and don’t put it on the wall!

Horrible App

You get an ad every time you press the detector button. The “close” button on the ads don’t work so you have to close the whole app!
Thats annoying enough to give it 1 star..

Other than that.. poor accuracy and poor interface. The accuracy may be because of my phone but I’m using an 11 pro..
