# GameOn > The operating system for youth football clubs. One login, one data spine, six > connected apps that run a club's weekly season, from trials, to the sideline > sub-bench, to season review, plus a tournament mode for festival days. Every app stands on its own, and each one gets sharper the moment the next one joins it. Free to start: no card, no trial timer. Five teams free on Club Manager. ## The apps - [Trials](https://trial.gameon.futbol/): rate players, build squads. - [Team Vote](https://vote.gameon.futbol/): RSVPs, training, wellness. - [Sub Manager](https://gameon.futbol/sub-manager): fair substitutions and match events on the sideline. Free app for iOS, Android and Apple Watch. Works fully offline with no account. - [Tournament](https://tournament.gameon.futbol/): festivals, cups and training round-robins. - [Tactical Board](https://board.gameon.futbol/): plays, sessions, decisions. - [Club Manager](https://club.gameon.futbol/): teams, results, stats. ## How data moves Trials sends squads to Club Manager. Club Manager sends teams and fixtures to Team Vote. Team Vote sends availability to Sub Manager. Sub Manager sends match events and play-time back to Club Manager. Tactical Board sends plays and sessions to Club Manager.
