Stud Detector and Stud Finder: Stud Finder Scanner is a stud detector app you can install in your phone to find metal and studs. It can detect studs between two walls so act as a wall detector. 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.
stud finder app is good for finding studs which you can’t see and don’t know where these stud, screw and bolt are placed. If you want to detect deep studs for AC wire detection this stud finder see through walls app can perform deep stud scanning and will detect stud and metal around the walls.
Stud finder app will detect common materials like wood and metal studs, drywall, copper, PVC pipe and stud finder in plaster. Stud finder and metal detector free app will easily scan the walls and earth, install the stud finder metal detector app and start detecting stud and metal through walls. Open the stud finder app and move it near any place like walls, plaster, earth or other place you want to detect.
Stud finder on your phone app works using emf sensor and magnetic sensor to quickly find stud and metal. While using metal stud detector app on your phone make sure that you have updated phone which have magnetic sensor.
It can find joist and is free of charge and it can be used as a stud sensor too.
Features:

• Adjustable sensitivity
• 3 distinct feedback levels
• Visual indication of feedback
• Displays magnetic field magnitude
• Configurable screen orientation
• Optional vibration feedback
• Optional audio feedback
• Optional wake lock
• Optional left-handed mode

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.

Thanks for downloading and using Stud Detector. I have constantly been updating and improving it.
Please consider leaving a detailed review of the app so future versions can be even further improved.

Wish you all happy and successful renovations!
