Smart Ring Pro, No App Subscription, Sleep & Activity Tracker with Heart Rate Monitoring, 7 Days Battery Life, IP68 Waterproof Fitness Ring, Compatible with iOS & Android(Matte Black,10)

[Size First Before You Buy] This smart ring features a wider and thicker ergonomic profile for optimal sensor performance. For the best fit, use the sizing kit before placing your order. If you are between two sizes, we strongly advise selecting the larger size. [Titanium Build] Made from resilient titanium alloy, the ring weighs around 3g. Owing to its smart sensor design, it may initially feel different from a conventional ring. Most wearers adjust within a few days of use for daily activities and sleep. [No Subscription Fee] The smart ring offers access to sleep, heart rate, activity, SpO, and stress trends without any app subscription fees. It is designed to aid daily wellness awareness, not to substitute for medical or professional devices. Your health data remains available without recurring charges. [Battery Life & App Connection] The battery provides up to 7 days of use depending on usage and settings. The ring syncs data periodically via Bluetooth to conserve power and may disconnect when idle. Charging duration and battery performance can vary based on usage patterns. [Water Resistant & Everyday Use] With an IP68 water resistance rating, the ring is suitable for daily activities like hand washing, workouts, and light water exposure. For comfort and skin care, we suggest removing the ring periodically, particularly during extended wear. [HSA/FSA Eligibility] This HSA-eligible and FSA-eligible smart ring permits qualified customers to utilize HSA or FSA funds for purchase. Featuring advanced health tracking, sleep monitoring, activity tracking, and wellness insights, it is a perfect wearable for men and women.
