Designed for runners, bikers, and anyone with a workout that gets them out and about, this sophisticated app uses GPS to track your routes and make the daily jog fun again. The app records your run, giving you a Google Maps view, lap times, and browsable workout history. Get motivated by pep talks from your friends and notifications every time you break a mile. If you take your runs really seriously, you can upgrade to the $3.99 paid version that integrates with Facebook and Twitter and can pull in data from popular heart-rate sensors and pedometers.
