Smart Ring Health & Fitness Tracker for Men & Women (Black, 13)

【SIZE BEFORE YOU BUY】 Smart rings can fit slightly snugger than traditional jewelry rings because of their wider, thicker design. Please check the Size Chart in Image 2 instead of relying only on your usual ring size. Measure your finger before ordering, and if you are between two sizes, choose the larger size for a more comfortable fit.
【EVERYDAY WELLNESS & ACTIVITY TRACKING】 Automatically track heart rate, stress, steps, calories burned, distance, and daily activity through the SmartHealth app. Review your daily and long-term trends in one place and stay more connected with your everyday routine.
【SLEEP & NAP TRACKING】 Wear the smart ring comfortably overnight to track nighttime sleep, daytime naps, sleep duration, and sleep stages. View your sleep records and daily trends anytime in the SmartHealth app to better understand your rest routine.
