Xiaomi Amazfit ZEPP E Round, Polar Night Black

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.

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 system, 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.

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). It provides you with the 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.

Keeping you motivated
Define a daily activity goal for yourself, including steps taken, calories burned and more, it can help you stay active more often. You can even set reminders to motivate you to get moving.
