Works as advertised … exactly once
So I was actually able to find the cables in the wall. Closed the app one day later I reopened it and now it wants sweet sweet money. It’s not worth 4 bucks, in all honesty it’s not that much more expensive to buy an actual device to reliably measure where the cables are. In the end this app plays with peoples lives do not trust the reading even when it worked in my test there is never a guarantee so yeah.
