Racing Slips app analytics for September 9

Here's the most useful app for drag racers at the Napierville Dragway race track. Get all your time slips directly on your phone. No more small piece of paper! You can even look at the history of your time slips (up to 50 races history per racer). Each history time slips include the Density Altitude at the moment of that single race! The Density Altitude is needed for serious bracket drag racers to properly calculate their dialin time for each race. The Density Altitude is updated every 5 minutes or so. This app only works for racers at the Napierville Dragway race track. If you are interested to get this app for your local race track, get the track owner to contact us for more details.
