TrackDay Pro Downloads & RevenueTrackDay Pro · App Store

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!!
