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

There are two ways to uncover AFib, right at your fingertips. With the ECG app, you can take an assessment on demand. Plus, use irregular heart rhythm notifications to look for signs of AFib while you're still or sleeping.

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.
