Fitbit Sense is the advanced health smartwatch that helps you tune in to your body with tools for stress management, heart health, SpO2, skin temperature & more.
- Stress Management allows the on-wrist EDA Scan app to detect electrodermal activity, which may indicate your body's response to stress- see a graph of your EDA responses in the app after each session and track trends over time. Use the tools to understand your stress, reflect on your mood, and make time for mindfulness, which may help reduce your stress.
- Compatible ECG App assesses your heart for atrial fibrillation (Afib), a common heart rhythm irregularity. Plus, stay informed with heart rate notifications when Sense detects that your heart rate is above or below your threshold. (Not recommended for under the age of 22 years old)
- Skin Temperature- It's more than a number. From fever to ovulation, temperature tells a story about your body. Sense has an on-wrist skin temperature sensor to track yours each night and show if it varies from your usual range, so you can identify changes in your trends over time.***
- Free Premium Trial, Sense unlocks a free 6-month trial for new Premium users so you can optimize your health with Fitbit. Get personalized insights, more advanced mindfulness, and stress management tools like a deeper look at your stress, guided programs to improve your nutrition, sleep, workouts, and more!
- Optimize your sleep and boost your energy with better rest. Track your time in light, deep, and REM sleep, then get a Sleep Score to better understand your ZZZs. And use the Smart Wake alarm to wake up during the optimal stage of sleep and be ready to take on your day.
- Smart in every way, with Voice to Text Replies, you can use the microphone to respond aloud to text messages right on your wrist without taking your phone out, for Andriod only. Take Bluetooth calls, get text and app notifications, get quick information from Google Assistant or Amazon Alexa Built-In, control music like Spotify, and more- all from your wrist.
