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!

Best Lap Analysis tool! Simple and Effective

Been using this app for a few months now and it has quickly become my favorite lap analysis app on the market! The app is super easy to use and compare laps immediately after a session or lap is completed. The map overlay and different comparison modes give me the necessary data to see the key areas where I need to focus on the most. Definitely the most fun, no frills lap timing app that continues to be improved. Highly recommend!

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.

Spot on for AutoX

I want something quick and easy to set up and use that’ll help me improve run times. SWHOON is all that. Minimum fuss, maximum useful information. Great for comparing runs with other users. Easy to use. And it continues to get better based in input from racers and autoXers.
