The track day lap-timer by track day riders, for track day riders (and drivers!) The customer feedback about racing leathers interfering with the GPS signal is correct! You *must* mount your iPhone externally to capture a good GPS signal while *riding* at the track. Details are provided on the GPS Accuracy screen accessed via the Support & Feedback menu selection. - Capture GPS data, then automatically compute lap times for each of your sessions on the track. - Download our tracks for FREE, have the app "learn" the track from your session data, or create your own track using the built-in track editor. - With Track view, analyze the raceline before you head out onto the track; back in the paddock, analyze your session results. - Email a CSV file of raw GPS data for the selected session for further analysis outside the app. - 270+ track configurations around the world and counting! Don't see the track you're looking for? Tell us and we'll add it!! Here are just a few of the tracks we feature: Anglesey International Aragon Arizona Motorsports Park Arroyo Seco Raceway Auto Club Speedway Autobahn Country Club Autodromo Fazenda Capuava Autodromo Jose Carlos Pace (Interlagos) BIR Barbagallo Raceway Barber Motorsports Park Baskerville Raceway Bedford Autodrome Blackhawk Farms Raceway Brands Hatch Brno Circuit Bugatti Circuit Buttonwillow Raceway Cadwell Park Carolina Motorsports Park Castle Combe Circuit Charlotte Motor Speedway Road Course Chuckwalla Valley Raceway Circuit Mont-Tremblant Circuit de Catalunya Circuit de Valencia Circuit de la Sarthe Circuit of the Americas Circuito Estoril Circuito de Jerez Daytona International Speedway Donington Park Dubai Autodrome Eagles Canyon Raceway Firebird International Raceway Gateway Motorsports Park GingerMan Raceway Goodwood Circuit Grattan Raceway Harris Hill Road Heartland Park Topeka Homestead-Miami Speedway Road Course Honda Grand Prix of St. Petersburg Iowa Speedway Road Course Isle of Man TT Jennings GP Kirkistown Circuit Kyalami Grand Prix Circuit Las Vegas Motor Speedway Lime Rock Park Losail International Circuit MSR Houston Mallory Park Superbike Circuit Manfeild Autocourse Mazda Raceway Laguna Seca Mid-America Motorplex Mid-Ohio Sports Car Course Miller Motorsports Park Misano World Circuit Monticello Motor Club Motorsport Park Hastings MotorSports Ranch Cresson Mount Panorama Circuit Bathurst Mugello Circuit NCCAR / NCBike NJMP NOLA Motorsports Park Nashville Superspeedway Road Course Nelson Ledges Road Course New Hampshire Motor Speedway Road Course Nuerburgring Nordschleife and F1 Circuit Oulton Park Circuit Pacific Raceway Road Course Palm Beach International Raceway Phakisa Freeway F1 Track Phillip Island Grand Prix Circuit PittRace (BeaveRun) North Track Pocono Raceway Portland International Raceway Putnam Park Road Course QLD Raceway Red Star Raceway Road America Road Atlanta Rockingham Motor Speedway Road Course Roebling Road Raceway Sachsenring Circuit Sebring International Raceway Sentul International Circuit Sepang International Circuit Serres Racing Circuit Silverstone Circuit Snetterton Sonoma Raceway Spring Mountain 2.2 Summit Point Motorsports Park Suzuka Circuit Sydney Motorsports Park Symmons Plains Raceway TT Circuit Assen Talladega Gran Prix Raceway Taupo Motorsport Park Teretonga Park Raceway Texas World Speedway Thunderhill Raceway Park Timaru International Motor Raceway (Levels) Twin Ring Motegi VIR Vereeniging Kart Circuit Wakefield Park Watkins Glen International Willow Springs Winton Motor Raceway Yas Marina Circuit Zwartkops Raceway and Kart Circuit Continued use of GPS running in the background can dramatically decrease battery life.
