Smart Ring Health & Fitness Tracker – Heart Rate, Sleep & Activity Monitor, 10ATM Water Resistant, 5–7 Day Battery

Everything a fitness tracker does, in a ring you'll actually want to wear. 💍

This sleek stainless steel smart ring tracks your heart rate, sleep, steps and workouts around the clock, then syncs everything to a free app on your phone. There's no bulky watch and no screen to distract you, just a lightweight ring you forget you're wearing. It's comfortable enough to sleep in, water resistant enough to swim in, and has a battery that lasts days, not hours.

Good to know

• Measure before you buy. Smart rings are wider than normal rings and fit more snugly, so if you're between sizes, go up one. Measure the finger you'll wear it on, ideally the index or middle finger, at the end of the day when fingers are slightly larger.
• This is a wellness and fitness device, not a medical device. Its readings are for general reference only and aren't intended to diagnose or treat any condition.
• It's water resistant for swimming and showering, but avoid saunas, hot tubs, diving and high-pressure water.
• Keep Bluetooth on and the app open for the first sync.

Wearing Instructions:

STEP-01: When measuring, please use a non-elastic thin string to wrap around your finger once.

STEP-02: Pull the string straight and measure its length with a ruler, then refer to the size chart above to select the appropriate size.
