Heart Rate
COROS watches measure your heart rate 24/7. On this graph you can view the maximum and minimum heart rate data. A different heart rate history graph is accessible on your watch via the HR widget. Heart rate data is taken every 10 minutes in standby mode and every second in workout modes.
