Haltech World Cup Finals
Maryland International Raceway, Nov 4 to 8. Follow every race, and pick your Fantasy Team. It's a free game.
Time your runs
Your phone is the timer.
Set your phone on the dash and go. Trofii times your 60 foot, eighth mile, quarter mile and 0 to 60, and the clock starts the moment your car moves. Got a Dragy or a RaceBox? Trofii works with those too.
- See where you gained and lost time on every run.
- Every run shows the air density, so a cold night and a hot afternoon compare fairly.
- Phone times and Dragy or RaceBox times are ranked separately, so it's always fair.
- Record video with your speed and times right on it.
At the track
Every race at the track, right on your phone.
For racers
When a track runs its timing through Trofii, you can follow the results live. Add your car number once, and your timeslips show up in the app on their own.
For the stands
At big events like the World Cup, you can pick a Fantasy Team. Choose five cars you think will go far and follow them all weekend. Not sure who to pick? Tap any car to see how it's done before. It's free to play.
Play
Drive real cars down a virtual quarter mile.
In Joyride you take someone's real car down the strip and see what you'd run in it. Cars that have been timed on Trofii drive just like they do in real life.
Perfect Light
Practice your reaction time on a Sportsman or Pro tree, so you're ready when the light turns green.
Studio
Make a video worth posting. Put your runs side by side so they all launch together, or put your time on your best photo of the car.
Community
Find your people.
Find groups and events near you, and follow the builds you like. Your car gets its own garage too, with all of its runs in one place.
“This app I can tell is focused on actual gear heads who build their vehicles. No social media trolls and so far the features are excellent!!”
