BreadCrumbz shows you real pictures of your route as you navigate, in addition to a map. Picture-based routes are easier to understand than map-based routes and are also more detailed, allowing you to do fun things like navigate indoors. You can easily create your own routes by “recording” them with your phone’s camera and GPS. When you’re done, simply email your route to friends or upload it to the web for the world to see with a single click.

BreadCrumbz uses the phone’s camera and GPS to take geo-tagged pictures of your route.

BreadCrumbz incorporates Android’s location APIs and Compass sensor to track your progress as you navigate.

Android’s Maps API is used to overlay route information on top of a map.
