Fitbit Sense Smart Fitness Watch Carbon/Graphite

Fitbit Sense is the advanced watch that helps you tune in to your body with tools for heart health, stress management, skin temperature trends & more.

Eda Scan App

The on-wrist EDA Scan app for Sense detects electrodermal activity, which may indicate your body’s response to stress so you can better track and manage it. Check your EDA responses in the Fitbit app to see how your body responded to a mindfulness session after using the on-wrist EDA Scan app.  See a daily Stress Management Score in the Fitbit app to quickly understand how your heart rate, activity and sleep all connect to impact your stress & overall health.

Mood Logging

Easily log your mood on Sense after an EDA Scan session or track it in the Fitbit app to recognise what makes you feel your best.

On-Wrist Skin Temperature Sensor

Sense is Fitbit’s first watch with an on-wrist skin temperature sensor to keep you informed and in tune with your body. It logs your skin temperature each night so you can see when your temperature changes from your usual range. These insights can help you understand patterns and spot trends when it comes to changes in your body, like fever or ovulation.

High & Low Heart Rate Notifications

Resting heart rate is a key indicator of health, so Sense keeps you informed when yours appears to be abnormally high or low.

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.

Swim Proof + Swim Tracking

Sense is water resistant to 50 metres, which means you’re free to track laps in the pool, wear it in the shower, at the beach and beyond.

All-Day Activity Tracking

Sense tracks all-day activity like steps, distance, active minutes and calories burned to show how every part of your day gets you closer to your goals.

Active Zone Minutes

Active Zone Minutes uses your resting heart rate as a baseline to track the time you’re spending in your target heart rate zones during exercise. You’ll see how your efforts add up and if you’re meeting the World Health Organization’s recommendation for 150 minutes of moderate activity or 75 minutes of vigorous activity per week.
