RunKeeper uses the GPS technology found in the iPhone to track your fitness activity, giving you comparable results to an expensive GPS watch at a fraction of the cost. Now, you can also enter your activities manually, including your treadmill runs too!
The intuitive and easy-to-use interface of the application makes it easy to track how far you went, how long it took, what your pace/speed was, how many calories you burned, and the path you traveled on a map.
Once your activity is completed, the data is synced to the RunKeeper website (runkeeper.com) where you can view a history of all of your activities, and cumulative totals of all of your vital stats. You can also share your progress with friends by posting your activities to Facebook and Twitter, and creating a profile page that allows people to view all of your public activities.

· Activity Tracking - No need for an expensive, standalone fitness tracking device when you can use your iPhone 3G or 3GS to do the same thing. Now you can track how far you went, how long it took you, and the route you traveled right from your iPhone
· Personal Dashboard - Store all historical activities on runkeeper.com, where you can keep track of totals and monitor your progress
· Maps integration - See the exact path you traveled on a map, both on the device and on our website
· Activity Sharing - Share your activities with friends via email, or by posting them to your favorite social sites, including Facebook and Twitter
· Music - You can listen to the iPod during your activity, and even change tracks without leaving the RunKeeper application
· iPod Integration - Choose one of your iPod playlists to start automatically the moment you begin your activity
· Audio Cues - Get time or distance-based updates through your headphones during your activity
· Interval Workouts - Create a workout built from intervals of time and/or distance, and let the audio cues coach you every step of the way
· Target Pace - Enter a target pace at the start of your activity and get coached on whether you are ahead/behind that pace through your headphones
· Geo-tagged Photos - Take photos without having to stop your activity. Photos are geo-tagged so when you view them on RunKeeper.com, they appear on the map right where you took them
· Splits - You can see your split times in the app as you do your activities
· Manual Activity Input - You can enter activities manually, including runs done on a treadmill or without your iPhone
