Yes. The ChessKid app features activities that Kids typically do on-the-go: playing Fast & Slow Games, working through Lessons, watching Videos & solving Puzzles. We've also added the ability to participate in Club Fast Tournaments to the iOS app, and are adding new features all the time!
Club features, Tournament set-up, Account Management and training tools such as Computer workouts, Articles, the Vision Trainer, Classroom Planner, and Chess Terms are only available on the browser version, ChessKid.com.
