Learn about your sleep habits

FB415 tracks several sleep metrics including when you go to bed, how long you're

asleep, and your time spent in each sleep stage. When you use FB415 with the

Fitbit dashboard, your watch can help you understand how your sleep patterns

compare to others of the same sex and age range.

FB415 uses PurePulse technology to track your heart rate automatically and

continuously. View your real-time heart rate and your resting heart rate on your

watch by swiping up from the clock screen to access your stats. For more

clock faces show your real-time heart rate on the clock screen.

During a workout, FB415 shows your heart-rate zone to help you target the

training intensity of your choice.
