I have tried cyclemeter and runkeeper, and kind of like runkeeper better. But is it optimized for the iPhone 6/6+ and does it work with the healthkit? Can't seem to see any information on that. I really wish Runkeeper incorporated a pedometer into the app to keep track of your steps and then to include that information into iOS 8's health dashboard automatically, that way I wouldn't need a 2nd app solely for that purpose. I want an all in 1 app for running with beautiful a beautiful interface.
