Sense logs your skin temperature each night to show how it varies from your personal baseline, so you can be aware of trends over time
resting heart rate is a key indicator of health, so sense keeps you informed when yours appears to be abnormally high or low. 
during outdoor runs, rides, hikes, and more, use built-in GPS to see your pace and distance without your phone on sense, then see a map of your workout in the Fitbit app.

Benefits:

• Better understand how your body is handling stress with a daily score. The on-wrist EDA Scan app detects electrodermal activity—which may indicate your body’s response to stress—and reveals a graph in the Fitbit app to illuminate it.
• Easily log your mood, from very stressed to very calm, on Sense after an EDA Scan session or in the Fitbit app to help you reflect on what makes you feel your best. With a compatible ECG app right on your wrist, assess your heart for atrial fibrillation—a heart rhythm irregularity—and share the results with your doctor.
• The Fitbit ECG app is only available in select countries. Not intended for use by people under 22 years old.
• Sense tracks your skin temperature each night to show how it varies from your personal baseline, so you can be aware of your trends over time. Track SpO2—the level of oxygen in your blood—to help you learn when there may be an indication of important changes in your well-being. See it at a glance on your wrist with a SpO2 clock face or swipe to your Today dashboard for average levels & trends over the past week.
• With an all-new multipath sensor, Sense delivers PurePulse 2.0—Fitbit’s 24/7 continuous heart rate tracking for exercise, sleep tracking, and everything in between. Automatically measure your breathing rate while you sleep to help you understand your wellness and learn if there are signs of significant changes. View your nightly average and trends over the past week in the Health Metrics dashboard.
• Track heart rate variability (HRV)—the variation of time between each heartbeat— to see if your body is showing potential signs of stress, illness, or fatigue. View your nightly average and trends over the past week in the Health Metrics dashboard. See your time in light, deep, and REM sleep and get a daily Sleep Score in the Fitbit app and on your wrist to better understand your sleep quality each night. Set your Fitbit alarm to wake you with a quiet vibration during a lighter sleep stage to help you feel more refreshed.
• Snooze uninterrupted by using sleep mode to mute smartphone notifications and stop your screen from turning on at night. Set a schedule to turn sleep mode on automatically. Find out if you’re snoring, or if there’s ambient noise in your bedroom—both of which can impact your sleep quality. Do what’s best for your body with a Daily Readiness Score that shows whether you’re ready to work out or should prioritize recovery.
• During outdoor runs, rides, hikes, and more, use built-in GPS to see your pace and distance on Sense, then see a map of your workout in the Fitbit app. Active Zone Minutes help you make every minute count during workouts by buzzing your wrist when you enter your personalized target heart rate zone.
