When the feature is on, the watch continuously measures your heart rate and
displays it on the Heart rate watch face. When opening the details, you can check
your highest and lowest heart rate readings of the day and also view what your
lowest heart rate reading of the previous night was.
The watch tracks your heart rate in 5-minute intervals and records the data for
later analysis in the Flow app or web service. If the watch detects that your heart
rate is elevated, it starts to record your heart rate continuously. Continuous
recording can also start based on your wrist movements, for example, when you're
walking with a fast enough pace for at least one minute. The continuous recording
of your heart rate stops automatically when your activity level drops low enough.
When your watch detects that your arm is not moving or when your heart rate is
not elevated it tracks your heart rate in 5-minute cycles to find your lowest reading
of the day.
In some cases, it is possible that you've seen a higher or lower heart rate on your
watch during the day than is shown in the continuous heart rate summary as the
highest or lowest reading of your day. This can happen if the reading you've seen
falls outside the tracking interval.
The LEDs on the back of your watch are always on when the continuous
heart rate feature is on and the sensor on the back is in touch with your
skin. For instructions on how to wear your watch for accurate heart rate
readings from the wrist, see
