Audio music and voice stops – iSmoothRun Review

I bought this for the walk run intervals. The first two times I used it it worked fine. The next time I stopped the app and when I went back in I couldn’t get any voice or music audio. I couldn’t even get the music from phone to play when app was not active. Disappointed in the glitch.
