Drag racing Time slips from the DER Series are currently printed using a receipt printer at the race track. This app shows the same time slips information on your phone. The app also enhanced the racer and spectator's experience at the race track by reading more detailed information from each race track on the phone in realtime (within seconds after each race). The app shows the weather station information and calculate the Density Altitude automatically to help the racers to tune their engines before racing. A first in the industry. This app lets you review drag racing time slips from the DER Series at any time. The racers can also use the time slips of their car# and show their car's performance base on the Density Altitude to help calculate your next Dial In at your next bracket drag race with your car.
