iPhone: RunKeeper is one of your favourite running apps, and today it has been updated with better support for the iPhone 5s. RunKeeper now support for the M7 chip that gives you access to all your movement history.
That means RunKeeper can track every step you take in the background without hogging your battery. With the app open, you'll get credit for every 15 minute (or more) walk you take, you'll see how big your strides are to help improve form, and the auto-pause function is vastly improved. If you're not the 5s, you get some new AirDrop features to share workouts.
