Daily Readiness

Optimize your workout routine with a Daily Readiness Score that reveals if you’re ready to exercise or should focus on recovery.1

EDA Scan App

The on-wrist EDA Scan app detects electrodermal activity–which may indicate your body’s response to stress so you can better track and manage it.

ECG App

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.2

On-wrist Skin Temperature Sensor

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.3

Understand Your SpO2 Levels

See your nightly blood oxygen levels at a glance with our growing collection of SpO2 clock faces. Then use the Fitbit app to track your trends over time in the Health Metrics dashboard to see when there may be indications of important changes in your fitness and wellness.

6-month Fitbit Premium Included

Personalized health & fitness guidance with a 6-month Fitbit Premium membership for new Premium users.4

High & Low Heart Rate Notifications

Your heart rate is a key indicator of health, so stay informed when Sense detects that your heart rate is unusually high or low.

Built-in Voice Assistant

Use Google Assistant or Amazon Alexa Built-in to get quick news and weather, set bedtime reminders and alarms, control your smart home devices and more–just by speaking to yoru watch.5

Calls from Your Wrist

Use the built-in mic and speaker to take Bluetooth calls hands-free, send callers to voicemail and adjust volume. (Available when your phone is nearby. Requires more frequent charging.)
