Amazfit Helio Smart Ring, Wearable Fitness Tracker

About Amazfit Helio Smart Ring, Wearable Fitness Tracker

• Sleep & Recovery Coach: Monitor sleep quality, stages and breathing, plus sleep heart rate variability and resting heart rate. Wake up to a readiness score that lets you know if your mind and body are recovered, or if you need a rest.
• Stress & Emotion Monitoring: For peak athletic performance, the mind is just as important as the body. The EDA (electrodermal activity) sensor monitors signs of stress and combines this data with your heart rate variability, to track your emotions.
• Crafted for the Best: Incredibly lightweight and made of titanium alloy, the Amazfit Helio Ring is less than 4 grams and 2.6mm. It's the ideal sleep tracker for everyone looking to monitor their recovery in comfort, without the bulk of a smartwatch.
• Precise Health Tracking: The ring hugs your finger for accurate heart rate, blood-oxygen and stress tracking, and curates specialized fitness data like VO2 Max, Full Recovery Time, Training Load and Training Effect for review in the Zepp App.
