📝 About this app
STUD FINDER / DETECTOR
This app will help you to detect studs. It uses the magnetometer to measure the magnetic field when your iPhone is placed near any metal objects. You can quickly detect wood studs hidden under walls, drywall, plasterboard or stucco.
DISCLAIMER: The performance of the app is limited by the construction of the wall, presence of a phone cover and/or the material of the nails in the studs.
INSTRUCTIONS: If your device has an external case then please remove it before using this app.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
