It covers heart rate zones and provides warnings when your resting heart rate is abnormally elevated.

Blood-oxygen Saturation Measurement As one of the most important factors of human health, the GTR 2e includes the SpO2 level measurement function. When engaged in intense mental or physical activity, measure your blood-oxygen level if you feel uncomfortable to keep your health firmly in your hands.	Sleep Quality Monitoring for Optimal Performance The GTR 2e offers in-depth sleep monitoring, which can accurately differentiate between the light deep and REM sleep periods, monitor the sleep breathing condition, provide quality analysis and suggestions for improvement based on a night of sleep, and recognize daytime naps over 20 minutes.	PAI Health Assessment System PAI (Personal Activity Intelligence) is a health assessment system that uses algorithms to convert complex data such as heart rate, activity duration and other health data into a single, intuitive score, unique to each user for easy understanding of your physical state.

Stress Level Measurement Check your personal stress level – relaxed, normal, medium or high – anytime you feel pressured throughout the day, so you know when to relax and reduce it.	90+ Sports Modes Activate one of the sports modes and the watch will produce a corresponding analytical report after you finish, to help you improve your exercise plan. Intelligent recognition of sports modes eliminates the need to manually select the sports mode, and 5 ATM water-resistance means you can wear it while you swim.	Liberate Your Hands You can perform voice operations, like turning on sports modes or opening the heart rate monitoring function, on your watch without internet access with the offline voice control feature.
