I was super excited to use this app for the holiday streak! I had been logging runs for 3 weeks but there was a problem changing miles to kilometers. I logged out and when I Logged back in, all of the runs I had entered were gone. Everything reset back to zero. In addition, the metric system could not be used and under "plans" there was a unending list of the same plan...the holiday streak. What a disappointment for an app that could be really great.
