Very user friendly. I used to have the nike run app but I never used it because when I tried playing music whether from steaming or whatever's on my phone the nike run app would stop so I was constantly stopping and going, more stopping for sure! With the map my run app,it works perfectly, plays any music I want, and it shows how much calories I've burned. The app only stops when I press the button.
