About Stud Finder

Stud Finder is a free iOS app from Appcellent. It uses the iPhone's built-in magnetometer to find the metal fasteners that hold drywall onto wall studs — so you can mount TVs, shelves, and artwork without extra hardware.

Why we built it

Most DIYers don't own a stud finder. We thought — every iPhone already ships with a sensor that can do the job. So we built a simple, offline, privacy-preserving app around it.
