Remember SportsTracker PRO? An app designed to help you track your training and beat your personal bests? The app has been updated to now provide support for Android Wear. If you are using the Samsung Gear Live watch, you will be able to read your heart rate from the watch sensor. Just start a GPS or Sensor only workout, and you will be able to see your heart rate in a few seconds. The app has also been improved in many other areas.
