Innerstar University is free for American doll owners with a specific code for the doll that is received after the initial purchase. The online "campus" offers different virtual activities including games and provides a safe platform where users can make friends, message each other and invite others to join in a game.
A new user receives 1,000 stars, which can be used to buy room decorations and outfits. The site focuses on positive feedback and once a game is complete, doll owners are given medals and awards that are kept in an online yearbook. Other highlights include a section dedicated to yoga, showing basic moves and providing encouragement during the exercise.
