The Sex Offender Tracker App (US$1.99), for the iPhone isn't the first such app in the App Store (Offender Locator and Sex Offender Search are two others), but it is the first to use augmented reality. As an added bonus, it has Antoine Dodson's approval.
The app uses your GPS location and a national database to identify registered sex offenders in your area. The information is presented as an overlay on top of video of your location. Users can specify search criteria and opt for a list view if the augmented presentation is less than ideal.
