Crumbs is a GPS-enabled path-recording application. When enabled, it saves a trail of digital breadcrumbs and displays it in real-time on a map. This app is great for hiking, biking, traveling, and other sports. Power consumption and path detail could be managed by changing the recording interval. Noisy paths could be simplified drastically (sometimes 97%) without significant loss of detail.
