UNDERSTAND YOUR STATS AT A GLANCE

Zepp E is a health partner that helps you understand multiple health metrics. With the cutting-edge bio-tracking optical sensor and leading AI algorithms, it’s easier than ever to track and analyze your wellness and fitness data.

INSTANTLY MEASURE YOUR BLOOD OXYGEN LEVEL
Blood-oxygen saturation (SpO2) is an important indicator of health, especially in high-altitude and low-oxygen environments or while performing high-intensity sports such as marathons or working out at the gym. With Zepp E, you can measure your current blood-oxygen saturation instantly from your wrist.
This product isn't a medical device. All data and measurements aren't intended for medical diagnosis or medical monitoring.

MONITORING YOUR STRESS LEVELS
Test your stress level any time when you feel anxious or panic, or turn on the continuous stress-monitoring mode to record 24/7 stress levels. No matter what kind of day you've had, the watch helps you understand your mental well-being.

UNDERSTAND HOW EXERCISE AFFECTS YOU
With the PAI™ health assessment systems, Zepp E factors in your heart rate, activity, and other metrics to give you an easy-to-understand PAI™ score. It allows you to intuitively understand your physical state. Since it's based on personal profile and heart rate data, it reflects your body's response to exercise.
To use this function, all-day heart rate monitoring must be enabled.

TRACK THE QUALITY OF YOUR SLEEP
The Zepp E not only tracks how long you rest but also the sleep stages—light sleep, deep sleep, and rapid eye movement (REM)6. It provides you scores on overall sleep quality and breathing quality. It even tracks a quick 20-minute nap during the day, so you get the full picture of your sleep patterns.
To monitor the REM cycle, the Sleep Assistant heart rate tracking mode must be enabled. During REM sleep, your eyes move quickly in different directions. The REM stage is the sleep stage related to dreaming.
