Couldnt be easier!

I love this app! I got this for my first half marathon and it is amazing. The beats do not over power my music but are still easy to focus on while running to the sound of my personal musical selections. I can use this app on the treadmill or the trails with no extra effort. I have an iPhone 6 and with my music, mapmyrun, and run tempo working together my battery life lasted for 3.5 hours.
Im very pleased!
