Tracks is an iPhone app for creating short photo stories with your friends on the go. Using the app you can create a sequence of images you take with your phone. You and your friends can comment on each shared picture. The app also lets you geolocate the images on a map to help tell your stories.

Applications for Education
When I first saw this app a few days ago I immediately thought that it could be useful for students to create stories about their neighborhoods and towns while walking. For example students could visit a series of important landmarks in their towns, take pictures, then work together to create a story by commenting on each image with information about the landmarks.
