This is a very good training app for training for a half marathon. I like the feedback both while on the run about my pace, and also being able to go back and track it after the run mile by mile. The music integration is good also no problems there. The only issue I have had is the sharing feature to social media sites such as Facebook. I have as of yet to be able to share my data, please offer a bug fix this very good app!
