GhostGauge is a racing companion for Forza Horizon 6 that records race results and brings timing, history, and community features together across the web, Windows, and Android. Its browser-based GhostGaugeWeb dashboard requires no app, while the Windows app offers an optional in-game real-time delta overlay and the Android app provides a local second-screen dashboard. Both installed apps can record races to a linked account.

Drivers can review lap times, sprint sector splits, personal bests, after-race summaries, and honours in My Races, then choose which results to publish. Leaderboards and track pages showcase records by car class, while the track directory includes official and community tracks. GhostGauge also supports organized league seasons and scheduled events, with entrant requirements, car rules, points, round results, and standings.

Community features include driver profiles with licence cards, clubs, and a Gallery for sharing in-game images. Crowns and Titles recognize records in areas such as speed, airtime, sideways driving, and distance.
