Introducing Swhoon – the ultimate app for empowering racers in their pursuit of speed. Whether you’re a professional racer or an enthusiast, now you can beat your own personal bests and race others. Get access to accurate lap data at tracks or events (powered by MotorsportsReg) around the country, and compare times and results with friends and other racers.

Swhoon provides a range of features so you can find out exactly what it takes to go faster! From tracking acceleration, racing line and braking points, to seeing where your friends and competitors stand in sector times – Swhoon can help you stay ahead of the competition. Plus, like and comment on performance to get even more insight into a lap.

You can use the iPhone’s GPS, but you need a high frequency BLE GPS receiver for the most accurate lap data. Don’t worry though; we currently support the popular Racebox Mini, Dual Electronics XGPS160 and Racelogic VBOX Sport receivers with more coming soon. 

So why wait? Come join us at the track!

Consistent and Easy to use

Ran Thunderhill East Cyclone with this app paired to a RaceBox Mini 25hz unit and had a great time. Transponder mounted onto the roof and phone mounted to the windshield made for some consistent readings.

It was nice being able to compare times with friends using the same app at the same event (so you know the conditions were the same).

I look forward to seeing future developments.

Amazing app

Coming from a professional driver who’s used multiple apps for lap times, data, etc, this was the best app I’ve ever used and it’s not even finished yet. The way you can analyze your line is incredible.
