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.
