Lethal is a practical iPhone app for a change: a nice little program that uses your phone's built-in location services to gauge where you are, then tell you how likely you are to be maimed, mugged, mauled or otherwise maligned.
Let's say you're walking through my neighborhood back in Berlin. It's Prenzlauer Berg, so it's plenty shady: on one street corner, three filthy, mad-eyed hobos roast a baby on a spit over a burning mattress. The gutters are thick with used needles and coughed-up lung tissue. Madly jactitating mad men wrapped in raincoats stained with genetic filth eye you lasciviously from the shadows, singing to you in German about the orifices they can smell. WIndows explode above you, accompanied by screams and buckshot.
But how dangerous is Prenzlauer Berg really? Well, just load up Lethal and it will tell you: a Wildlife Rating of Zero, Crime and Disease bars maxed, and a Disaster Rating hovering around 80, since God's cursed it and all. Good to know for only $1.99.
