A life saver

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 couldnt find the key anywhere. Since theres 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.
