How do I track breathing rate in the Fitbit app?

Wear your device for at least a full day, including to sleep at night. Then check your stats:

1. In the morning, open the Fitbit app. In the Today tab , tap the Health Metrics tile  .
2. Tap Breathing rate (BR) to check the graphs of your nightly average breathing rate over the course of a week, month, or year.
3.  In the Week view, tap Learn More above the graph for an even better understanding of how this metric is calculated.
