Always drive safely. Intended for responsible use in a motorsports environment. Use at your own risk.

Works on iPhone and compatible GPS-enabled iPad, iPad mini, and iPod touch devices. Devices which do not contain suitable GPS hardware may work when combined with a compatible external GPS device. Performance depends on good GPS reception conditions, and may vary. Features, capabilities, and pricing may differ between platforms and are subject to change at any time.

OBD functionality is optional, and would require a supported OBD-II interface device and a compatible OBD-II compliant vehicle. See website for details.

Features and capabilities can vary depending on your device and other circumstances.

Use of Live Streaming feature is optional. Services are provided as-is, and are subject to change or discontinuation at any time. This functionality does have privacy implications. Please see this app's online documentation and before enabling its use.

Continued use of GPS running in the background can dramatically decrease battery life.

Great, Economical Driver Feedback

After 32 years I went back to SCCA Solo II competitions, and suffice it to say my high speed driving skills were rusty. TrackAddict won’t singularly transform you into an “alien” (freak fast driver), but frankly nothing will except seat time. So the question is how do you apply lessons learned to not only drive fast, but become a fast driver? TrackAddict is part of a recipe that works for me. By using this app I was able to see how my in-person feedback compared to the data of what the car was actually doing. If you are a national-level driver you may want something more complex such as SoloStorm, but for the rest of us this is a superb tool.

Difficult to use and debug

I bought an external gps unit to increase responsiveness and accuracy of gps data. Every time I use it the gps causes the delay of all overlaid data including obd data. I wouldn’t mind this if there was an easy way to adjust the offset between the video and the data streams overlaid but alas I couldn’t find it in the myriad options. I’m also trying to sync them with RaceRender (made by same people) and I can’t seem to be able to do that easily. Otherwise data gathering is great but what use is it without a visual image. :-/

Great budget timer

This app is great for those of us who like to go to the track but don’t want to break the budget doing it. Using this app has allowed me to improve greatly in a short period of time. I can review my data and video between session which allows me to make improvements from one session to the next. The timing is also very accurate; usually within .01 of a second compared to official lap timers.
