When you open the session in TrackAddict, there is a "Share" button that will give you an option to post your best lap (or your run stats, if it's a Segment or Drag Race recording). After selecting that option, you'll be prompted with a list of apps you can post this to, including Facebook, Twitter, etc., if you have those installed. TrackAddict will generate some text with stats in it, as well as an image of the track map with a little bit of text on it (or a virtual time slip for drag mode). Depending on the app you send it to, it may accept one or the other, or both. Most notably, Facebook will intentionally reject the incoming text from apps, so all that you'll get is the image.
At this time, this share option only applies to the detected best lap of a session, rather than individually selected laps. Also, the Android version of TrackAddict does not have combined video+data output just yet (we'll be working on that as a premium feature), so the solution for video there is to bring your session data and video into our
RaceRender desktop software (the WiFi transfer feature makes this easy)... It will enable you to output up to 3 minutes of video at a time for free, which should be plenty for sharing most single laps, autocross runs, drag race passes, etc.
