For nervous nellies constantly worried about becoming the victim of a crime, iPhone app Are You Safe will stoke your paranoia with a "threat meter" based on your location.
Walk into a red zone? A crime data heat map will guide you to somewhere safer.
However, it only seems to track violent crimes and car thefts -- which won't help you when you're being conned by a white collar criminal. In other words, useless on Montgomery.
The app is available for San Francisco, Atlanta, Washington D.C., Sacramento, Indianapolis, Milwaukee, Chicago, Dallas, Cincinnati and Virginia Beach.
