GameChanger is a US-based technology company whose mobile app and website provide scorekeeping, stats, video streaming, and recap stories to teams and connected fans at the local level.

[2] The concept is that by providing free software to coaches in exchange for their information, GameChanger can collect and manage a massive pool of information that is valuable to parents and fans, making an impact in a market (amateur sports) that is inherently decentralized.

[3] During the game, a Team Admin records the action on the free GameChanger app—tapping simple menus to score every play.

A live GameStream of plays and stats is instantly delivered to fans following from the GameChanger website or their mobile devices.

MaxPreps, the Cal Ripken World Series, Perfect Game, and USA Baseball all became partners in 2011.

In April 2018, GameChanger announced a partnership with the National Federation of State High School Associations.
