This iPhone running App let me focus on my jogging without having to look through my library constantly to find the right song. I could keep my eyes on the path instead of on my iPhone.

In the settings you can set it to be exactly the same tempo of the song that you listen to and rate as you run in, or if you want the song to have a few percent faster BPM, for you to increase speed.

You can also set how the songs should be mixed and more.
