Sacramento Raceway · Test & Tune · iOS beta on TestFlight
RACE THE
NUMBER.
Every car in here is a real measured pass — your phone's GPS and accelerometer, fused into a curve. We correct every run to one standard day, so you race the cars, not the weather. Nobody meets. The only live thing is your launch on the tree.

How it runs
Record. Correct. Call someone out.
Real cars, not stats
Mount your phone, make a pass. GPS speed + accelerometer, fused into a real acceleration curve. No spec-sheet numbers — the run is the car.
Same air, always
Hot day, cold day, altitude — every run is transposed to one standard day before it races. You beat the driver, not the weather. How the correction works →
The tree is the game
Cars are recorded ghosts; nobody's live. Stage, watch the ambers, release on the green. Cut a better light and the win is yours.
