Couch to 5K app for Apple Watch

I am starting a couch to 5K program and downloaded the C25Kpro app that claimed to be fully integrated with the watch but I did the first workout and the I don't have access to music, it didn't sync to my Health app and I can't view my workout stats in the app.

Are there any Apple Watch users doing this program? Which app do you use? I do not want to carry my phone with me.
