About this app

Need to quickly locate wood studs hidden under drywall, plasterboard, or stucco in order to safely and securely complete your renovations project or simply 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 magnetic metal fasteners in wood studs located beneath the drywall, plasterboard, or sheetrock in every wall.

IMPORTANT: Your device's magnetometer cannot detect wood directly but only detects magnetic METAL fasteners within the wooden wall studs themselves!

WARNING: Please watch, read, and carefully follow included instructions on how to successfully use the app before leaving a negative review without understand how to correctly use the app!

A stud detector is a must have tool for any do-it-yourself, renovator, handyman to securely hanging heavy wall fixtures by ensuring the fasteners are well anchored in the wall studs. A must have companion renovation app!

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.

I tested the app against a store bought stud finder and consistantly got similiar results. I noticed that the phone's ability seems a bit weaker so the LEDs will flash briefly, but it actually worked. Very cool use of built in phone technology. Imagine what future devices will be capable of.
