This weekend's NMRA/NMCA Super Bowl of Street-Legal Drag Racing Presented by HPJ Performance at World Wide Technology Raceway requires racers to use a Time Slip App, which can be downloaded free of charge and it is available through the Apple App Store and Google Play. The track does not issue paper time tickets so it is important for competitors to download the app prior to the event kick off on Thursday, May 13. The Time Slip is available to download through this link https://www.dynogeeks.com/apps/wwtr The center screen is the main screen, if you swipe right you will get the current weather, if you swipe left you get the Car # filter screen. Here, you input your car # and it will find all your runs, you can swipe up to view previous runs. The main screen will show the last run down the track, simply swipe up if you want to see previous runs, or search by your car # on the right screen. WWTR recommends new users watch the introduction video when they download the app; it will pop up and ask if you want to watch instructions. It is about 3-minutes and explains everything in the app.
