Smart Ring Health Tracker Waterproof Heart Rate Blood Oxygen Monitor BT4.2 Step Calorie Counter Fitness Tracker for Android/iOS

Smart Ring Sleep Health Monitor Waterproof Bluetooth-Compatible4.2 Heart Rate Blood Oxygen Tracker Step Calorie Counter for Android/iOS
Feature:
1. Advanced Sensor Technology: With wireless wristbands and Bluetooth-Compatible watches equipped with a wide range of sensors, this smart ring can not only measure our heart rate but sometimes even detect irregular blood oxygen levels. It’s amazing how such small and fashionable smart ring can provide valuable insights into our health, going beyond just accessing data to truly understanding it through wearable devices.
2. Comprehensive Health Monitoring: While most smartwatches and fitness trackers display data like heart rate and sleep duration, they often fail to provide a deeper understanding of our overall health. In contrast, the smart ring measures the same metabolic biomarkers such as heart rate variability, body temperature, and sleep while presenting them in a more easily comprehensible and actionable format.
3. Activity and Sleep Monitoring Indices: The development of step index aims to help you understand daily energy expenditure based on your overall activity throughout the day rather than just specific durations of exercise. Sleep index goes beyond sleep duration and incorporates different sleep stages such as deep sleep, REM sleep, light sleep, and wakefulness, helping you determine if you need more deep sleep stages.
4. Stylish and Functional Design: It is crucial to monitor your activity, sleep duration, heart rate, blood oxygen, and take appropriate actions to improve your health and potentially save your life. Combining smart applications and elegant hardware, the smart ring offers this deeper functionality authentic to your body condition while looking stylish. Say goodbye to bulky smartwatches and Bluetooth-Compatible wristbands.
5. Long-lasting and Waterproof: Designed for continuous monitoring of your body, this smart ring utilizes patented energy-saving technology, delivering up to 3 days of usage without the need for charging. It also features IPX8 level waterproofing, making it resistant to water and sweat. This smart ring, based on a combination of daytime step counter, heart rate, blood oxygen, and body temperature, helps you better understand various body signals.
