SocialRunner app for iPhone and iPad

Social Runner is a GPS enabled running computer that tracks distance travelled and feet climbed. It allows your iPhone to function as a GPS device / altimeter for capturing your running adventures. From your iPhone, you can post your file to Strava or send the file to yourself for uploading to Garmin or other sites. From your iPhone, you can post details about your latest ride to Facebook and/or Twitter. You can also pull up saved files on your iPhone and replay the statistics from that ride.

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