A life saver – Metal Detector Review

Long story short, left a house key out for the dog sitter prior to going away for the weekend. When we returned home we searched and searched but couldn't find the key anywhere. Since there's an app for everything and I was desperate I downloaded this app. How could an iPhone actually be a metal detector...I know I know. HOWEVER, I gave it a shot. Found the key in 1 minute. It works folks.
