Could be perfect

I have used Beatburn for years now, and really love this app. The only and very annoying feature missing is for the voice guide to provide speed in kilometers and not just miles. I live in Denmark, my treadmill uses kilometers, and my Beatburn settings are also kilometers. When exercising, I have to constantly check the kilometers on the display, as the speed can only be voiced in miles.
