Only detects metal

Studs are made of wood

It’s not free

This app is a joke, it kept popping up adds for $1.99 upgrade every .10 seconds. All I need is to find a stud once why would I pay a fee from a free app?

Nothing but ads

You can only use the app for about 5 seconds before being prompted to upgrade or wait 10 seconds to continued followed by the same pop up only 5-10 seconds later
