This app was finally updated and now has full Watch Support. Through Health Kit runs now sync in both directions (runs started in Activity and runs started through the Nike app appear in each app and totals and Nike runs show up in Activity with the icon and everything). All data appears to sync over. The only data that does not appear to sync over is heart rate from Activity runs do not appear in the Nike Running Club app. The Nike app uses Watch heart rate during runs and it seems to work great. I did a 2 mile test run and the new Watch app appears to work really well. Any thoughts or observations from anyone? Give it another chance.
