I am still waiting on my watch to arrive in the mail, but I wanted to go ahead and download the app so that I could familiarize myself with it. One of the first things that it asks is "how do you plan to use the app" and gives you two options: health or fitness. I was just clicking through and accidentally clicked fitness and now, I have no way to go back and change it. Is there a way to change it that I haven't figured out or will it even make a difference with me using the app?
