About Stud Detector

Need to quickly detect wood studs hidden under drywall, plasterboard, or stucco in order to safely and securely hang a mirror, shelf, TV or other large wall fixture? Stud Detector turns your mobile device into a studfinder tool! Stud Detector uses your device's compass (magnetometer) sensor to precisely target wall studs by pinpointing metal joists, nails, screws, or 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.

Stud Detector 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) Stud Detector 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, studfinder apps cannot detect wood studs themselves, but rather, detect the metal fasteners embedded within them. Please keep this difference in mind when using Stud Detector.

No legit stud finder in the app store they are all garbage and don't work don't put holes in you're wall. Need to find a stud go buy a real stud finder from Lowe's or Menards. Real contractors will say the same thing.
