For data-obsessed athletes who don't want their GPS-tracking app shouting motivation into their earbuds, there's My Tracks. Fire it up as you start running, hiking, or biking and the app will record everything from speed and distance to wonkier readings like elevation gain and heart rate (with an external strap).
