The build ahead

Live timing connections, spoken crew-chief calls, race dashboard, driver preferences and supported-track expansion.
Native mobile publication is planned as the app matures beyond its current PWA development stage.
Planned GPS-sender support will add a more precise source for lap and sector times, combined with the track's live session and race information.
