I have tried several running apps and this is by far the worse. Youll be tricked into the "free week" of Pro by upgrading. The problem with that is you get charged the $9.99 right away, not a week later. So if you dont like it, you have to pay $9.99 to find out. Save your money and go with a different running app - there are a ton of couch-to-5K type apps out there that are better.
