About this item

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.
No Subscriptions Required: All features are available upon purchase. Amazfit Helio Ring users even can get tailored sleep music and health assessments from Zepp Aura, plus fitness reports and an AI sports-focused chatbot from Zepp Coach Premium, for free in the Zepp App.
Your Recovery Snapshot: Glance at the top of the Zepp App homepage for scores and insights for your readiness, sleep score, sleep heart rate variability, sleep resting heart rate, and full recovery time – all collected together.
All Your Data in One Place: Train with your Amazfit smartwatch during the day, rest with your Amazfit Helio Ring at night, and check all your data from both devices in the Zepp App. Get performance and recovery analysis, and actionable insights.
The Helio Ring may be worn on any finger without any data degradation
