[Size First Before You Buy] This smart ring features a wider and thicker ergonomic profile for optimal sensor performance. For the best comfort, use the sizing kit before ordering. If you are between two sizes, we strongly recommend selecting the larger size. [Titanium Build] Made from durable titanium alloy, the ring weighs around 3g. Due to its smart sensor design, it may feel different from a regular ring initially. Most users adapt within a few days of wear for daily activities and sleep. [No Subscription Fee] The smart ring provides access to sleep, heart rate, activity, SpO, and stress trends with no app subscription fees. It is designed to support daily wellness awareness, not to replace medical or professional devices. Your health data remains accessible without recurring payments. [Battery & App Connection] The battery can last up to 7 days depending on usage and settings. The ring syncs data periodically via Bluetooth to optimize power consumption and may disconnect when idle. Charging duration and battery performance may vary based on usage habits. [Water Resistant & Everyday Use] With IP68 water resistance, the ring is suitable for daily activities such as hand washing, workouts, and light water exposure. For comfort and skin care, we advise removing the ring periodically, especially during extended wear. [HSA/FSA Eligible] This HSA and FSA eligible smart ring allows qualified customers to use HSA or FSA funds for purchase. It features advanced health tracking, sleep monitoring, activity tracking, and wellness insights, making it an ideal wearable for men and women.
