It proves whether you have a functioning magnetic sensor or not in your phone, but I'm skeptical about the readings. It's fun to use, but the specifics are sorta variate.
Used it to find studs. Worked great because you can see the actual tesla value instead of dots.
Free party favor, would not recommend it to locate anything important .
This app does exactly what it says it does, its great!
It "works". Not very useful to me. Maybe to others. Uninstalling.
Great tool I really love it, I found an old gold ring in my yard.
