GREEN FLAG — TRACK CLEAR
Passing allowed in designated zones per run group rules
Why Drivers Love the Live HUD
Designed specifically for drivers in grid line-ups and hot pit lanes. High-contrast typography and instant status updates make track situational awareness effortless.
Instant Race Control Flags
Tower flag triggers (Green, Yellow, Debris, Meatball, Red, Black, Checkered) appear instantly on screen with high-visibility color blocks and distinct audio tones.
Stint Countdown & Grid Staging
No more guessing how many minutes are left in your session or missing your staging call while checking torque specs in the paddock. Accurate to the second.
Offline & Spotty Wi-Fi Resilience
Built as a Progressive Web App (PWA). If cell reception drops on Sebring's back straight or Roebling's paddock, the app gracefully reconnects with zero lockup.
100% Free with Registration
