About this app

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 conducting fasteners in wood studs located beneath the drywall, plasterboard, or sheetrock in every wall. A stud detector is essential for DIYs to securely hanging heavy wall fixtures by ensuring the fasteners are well anchored in the wall studs.

Studfinder operates in a similar manner to other hand-held stud detector tools: LED lights light up in sequence with proximity to stud as your device's magnetometer passes over the stud. However, because modern mobile devices do not have density sensors (which are used by real studfinder tools) Studfinder uses your compass (magnetometer) sensor to detect subtle changes in the background magnetic fields caused by conductive metal fasteners embedded in all studs. Because of the lack of a density sensor in mobile devices, studfinder apps cannot detect wood studs themselves, but rather, detect the metal fasteners embedded in them. 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

Thanks for downloading and using Studfinder. 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!

It's a shame that so many do not understand that they must have a Magna meter on their phone and that magnets do not work with wood! As a commercial Tradesman many of the buildings I work with have metal studs. This app works extremely well in this situation. I'm using this app on an S9 Plus where the sensor is combined with the fingerprint scanner. Works wonderfully because it is now in the center of the phone!

Great to hear! Thanks for taking the time to review, and so glad you find it useful and understand how to use the app when so many others don't follow the instructions before leaving nasty reviews!
