Users were able to register interesting paths, include interesting locations for roller skating, find and create activity groups, follow friends, post photos to a specific location, post in a timeline, add events to a calendar, among other functionalities. In addition, a map informed how many online friends were nearby. The application motivated users to visit locations and to learn new tricks, by grading them and gifting badges based on objectives.
