Today's Free App of the Day is C25K Pro
This is an app that will allow you to start an exercise program that will allow you to run a 5K (3 Miles) in 9 weeks. Or at least be a lot more fit. I don't think you have to be planning to run to get benefit from this program.
You can play music and also have separate prompts and set different volumes for each.
Reviews are generally quite good.
