Thanks to Retina-X Studios you can now spy on your friends, family, children, and employees with absolute impunity. The app designer has just released the Mobile Spy 3.0 app for the iPhone, which allows users to surreptitiously monitor everyone who contacts them. The clandestine program runs as a background app, and automatically tracks and records SMS messages, phone calls, and GPS locations.

Get a text from your kid saying he's 'staying late at school'? You can track down where he sent the SMS from and find out whether or not he's telling the truth. You can do the same thing with phone calls, which makes the Mobile Spy app the greatest breakthrough in 'being a creepy stalker' technology since the invention of the binoculars.

"Mobile Spy is a priceless piece of software. After having some doubts about honesty, this really helped set the record straight and confirmed my suspicions," said one Mobile Spy user.

I think we can all agree that technology like this is just slightly terrifying. On the other hand, it does fulfill a legitimate need many people have. If you, say, own a delivery company, you can keep track of where all of your employees are by tracking their company issued cell-phone GPS signal. Mobile Spy is very confidential, and automatically uploads all data to a separate website where you can access it.

If this product is your kind of scary, you can download it here for a stiff $99.97 per year. Which we guess isn't a very bad price, considering how expensive tracking devices are these days.
