Lethal is a 99¢ iPhone/iPod Touch application. According to the review at The Unofficial Apple Weblog:
• LETHAL now gives a risk ranking for every US and Canadian town or city with a population over 100,000, plus all Canadian National Parks. If you’re within a large metropolitan area, you can watch your LETHAL index change as you drive around.
• More disasters! More dangerous animals!
• The crime information is more specific, with new updated crime data from the FBI database.
• You can view rankings for all locations from most dangerous to least (or vice versa) for all indexes and specific risks. Want to find the #1 area to get killed by a grizzly bear? LETHAL can help.
I think I can get 99¢ worth of fun out of this just while driving down Central in Albuquerque.
Update: Data is actually not yet granular enough to show variations within a city the size of Albuquerque.
