Know your number before you stage.
The Bracket Racer predicts your car's next elapsed time from live track weather, then learns your car from every run you save — so your suggested dial-in gets sharper every meeting.
Built for Australian bracket racers, with live weather for major strips including Willowbank, Sydney Dragway, Perth Motorplex, The Bend, Warwick, Springmount, Calder Park, South Coast, Mildura and Hidden Valley — plus manual weather entry for anywhere else.
HOW IT WORKS
Save one baseline run — your ET, 60ft, MPH and the density altitude it was set in. From there the app corrects your prediction for the air you're actually racing in: density altitude, humidity, barometric pressure and headwind or tailwind down your strip's true heading.
IT LEARNS YOUR CAR
Every run you save teaches the predictor. It weighs runs from the same track and similar air more heavily, ignores the odd bad pass instead of averaging it in, and shows you exactly how much it has learned. Watch the accuracy build with your run history.
MADE FOR RACE DAY
