Are there some other number you care about a lot? You could track them on Google analytics and show them on your smart watch.
1. Open the phone app and select the analytics web property.
2. Select "Analytics Watch Face" on your Android Wear companion app or on the watch. It may take a few minutes before the watch face show up after install.
