About this item
- Size Before You Buy: Smart ring sizing may differ from standard jewelry rings. Please use the size chart and sizing guide in the product images to measure the exact finger you plan to wear it on and confirm your US ring size before ordering. If you are between sizes, choose the larger size.
- All-day Health and Sleep Tracking: This smart ring health tracker records sleep, heart rate, blood oxygen SpO2, HRV trends, stress, steps, distance, calories, and daily activity in the app. Wear the sleep tracker ring during the day and overnight to better understand how your rest, movement, exercise, and everyday habits change over time.
- Smart Ring for Men, Women and Busy Professionals: Designed for men and women who want a compact fitness tracker without wearing a bulky smartwatch. Suitable for office workers, busy professionals, commuters, travelers, and everyday users who want to review sleep, steps, calories, stress, and wellness trends during workdays, weekends, and travel.
- Women's Health with No Subscription Fee: When the app profile is set to female, this smart ring for women supports menstrual cycle tracking alongside sleep and daily wellness records. All available app features can be accessed without a monthly subscription, paid membership, or recurring feature fee, with no hidden cost required to continue using the app.
- 180+ Sports Modes for Active Lifestyles: This fitness tracker ring supports more than 180 sports and activity modes, including running, walking, cycling, yoga, strength training, hiking, golf, dancing, and many indoor or outdoor workouts. Use it at the gym, during morning walks, outdoor training, home workouts, and active travel, then review your activity trends in the app.
- Honest 3-Day Battery and Ip68 Waterproof: Get about 3 days of typical use from a full charge, helping reduce frequent charging without overstating battery performance. Actual battery life varies with measurement frequency, sports tracking, app settings, and usage. The IP68 waterproof smart ring is suitable for handwashing, rain, showers, swimming, sweaty workouts, and everyday wear.
