Since I got my HTC Hero in December last year I have always been browsing the Android Market and Web for some cool apps, and I think this is really one of the coolest apps out there. Cool and extremely geeky.

So you are in a hurry and you lost your keys somewhere in the couch where you were chilling, no problem! Just get your Android phone and fire up the Metal Detector app and swipe it over the couch, it will start vibrating when it passes the keys.

The Metal Detector app works on all Android models that has the built-in magnetometer that is used for the compass. Wow sorry normal Apple iPhone users, I believe only the iPhone 3Gs has this functionality.

Here is a video demonstrating the Metal Detector App

Android users get your Metal Detector App for free from the Android Market, just search for “metal detector”. BTW if you haven’t got a Google Android based phone yet, you can win one at Web AddiCT(s);
