Math Champ Client serves as a game controller for a groundbreaking quiz game tailored for classrooms, targeting grades 4 to 7. Compatible with iPhones, iPads, and iPod Touch devices, this app allows students to engage in real-time math challenges against their peers to claim the title of Math Champ. To initiate gameplay, users need the Math Champ Host application, classmates to compete against, and the Math Champ Client. The Host generates quiz sets from a vast question bank based on common curricular standards, sending questions to each player's device as the quiz progresses.

Players earn points for correct answers, with additional bonuses for speed and consecutive correct responses. The leading scorer at the end of the quiz is crowned the Math Champ until another contender surpasses them. For a glimpse into the Math Champ experience, a video is available on the developer's website. It's important to note that the Math Champ Client requires the separate purchase of the Math Champ Host application for full functionality.
