Other than the watch face, nothing is working. You need to use safari to see the dashboard, but there are no settings other than your personal data, height, weight, age, etc. sleeping data doesnt seem to be implemented, I have worn the pebble to bed three days, still no sleep data. No option to set sleep times, so I am not sure how to use it. Again, I have worn the watch for three days with this app and the dashboard shows no muv data. I am not sure what I got other than an expensive watch face. :(
