iPhone / Sports
TrackR is the bracket racer's data logbook and dial-in predictor — built by racers, for racers.
Log every pass in seconds, let TrackR learn your car, and walk up to the lanes knowing your number. Every ET prediction is backed by real math — no black box.
PREDICT YOUR DIAL-IN

• Automatic weather and density altitude at your track

• Win/loss and round-by-round history
KNOW YOUR CONDITIONS
• Live density altitude for your track
• Hourly ET forecast — find the best window to run
