| Platforms | iRacing · Windows · web companion on iPad/iPhone/Android | iOS · Android · Windows · games: AC, ACC, F1 2020-25, Forza, Gran Turismo, iRacing, Le Mans Ultimate, Project CARS 2, RaceRoom, rFactor 2 |
| Standout feature | Community datamart of thousands of uploaded laps to compare braking points, lines and gearing against faster drivers | Advanced Analysis mode comparing throttle/brake, steering, gear, RPM, speed and g-forces across laps on a tablet with track-map overlay |
| Weakness | iRacing-only and visibly dated — the official site still lists compatibility as Windows XP through Windows 8, and unlicensed copies show periodic donation prompts | Advanced Analysis requires a full-HD-or-better tablet/desktop screen, Forza Horizon/FM7/Gran Turismo expose only limited telemetry, and AC/iRacing need a Windows relay app installed on the game PC |
