Pebblebox allows the user to publish and discover local events, theater schedules, housing, restaurants, tourism guide, etc. It is also a social platform in neighborhoods. Users can read and write geo-blogs, share experiences, and make new friends. Furthermore, it supports transactions on mobile phones. Users can sell and buy products, purchase tickets, make reservations, etc.

Using Android Map API to overlay a variety of selectable items on the map to maximize the space usage gives users a straightforward view of the current location, and a sense of distances and directions.

PebbleBox uses the always-on data network connection provided by the Android platform to fetch user-interested content, make new posts, and complete transactions. It also uses a background service to improve the energy efficiency by finding the best network conditions for communication.
