HK01 Smart Ring for Women & Men, Sleep & Stress Tracker, Waterproof Fitness Ring for iOS & Android, No Subscription Fee (Silver, Size 9)

Please measure carefully before ordering. Smart rings require a more precise fit than regular jewelry for comfortable wear and accurate tracking. Measure the exact finger you plan to wear the ring on before purchasing and compare it carefully with the size chart. If you are between sizes, it is generally recommended to choose the larger size for better comfort during sleep and all-day wear. Lightweight and comfortable for daily wear. Designed with a smooth, lightweight jewelry-inspired shape for comfortable day and night wear. Finger sizes naturally vary between different fingers, and many users comfortably wear the ring on the index finger or ring finger if another finger feels too tight. Thoughtful sizing and comfortable wear help create a better long-term wellness tracking experience. Sleep and stress tracking for daily wellness. This device helps track sleep patterns, stress levels, heart rate, activity, and daily wellness trends through the companion app. Designed to support better awareness of your daily rhythm and lifestyle habits in a simple and comfortable way.
