I love this app; I have used it for my first marathon and everything went great on race day; except one little thing. I accidentally touched the "done" button and it shut off. I had to restart the app which of course is now giving faulty info on pace, miles etc. It needs a cover screen that allows for music controls but forces a more deliberate action to pause or stop the current "run". This has happens several times during training, too.
