About this item
- Get the right size first – Sizing kit recommended：We recommend ordering our sizing kit first to help you choose the correct size. Wear the tester ring for 24 hours to confirm which size fits you best. Or measure the widest part of your finger with a soft tape or paper strip, then compare with our size chart. No half sizes? Choose the larger one – your finger may swell during the day. After receiving your ring, download the free app to pair and start using it.
- Accurate activity tracking – Multi-sport modes & GPS route：Whether you're on a morning run, cycling to work, hiking on a trail, or hitting the gym, this fitness tracker ring automatically counts your steps, distance, and calories burned. Use your phone's GPS to map outdoor routes and review them on the app. A perfect activity tracker for women who love outdoor adventures, and for men who want a reliable fitness ring for daily workouts.
- 24/7 health tracking – Heart rate, SpO₂, sleep & stress：Wear it day and night – while sleeping, working, or relaxing. Get continuous tracking of heart rate, SpO₂, sleep stage analysis (REM, deep, light), and daily stress levels. This sleep tracker ring helps you understand your rest quality, while the health ring shows long‑term trends through the free app. A true health ring for women and fitness tracker for men – no subscription, no hidden fees.
- IP68 waterproof – Swim, shower & sweat without worry：Rated IP68 waterproof, this ring can be worn while swimming laps, showering after gym, washing hands, or jogging in the rain – no need to take it off.
