VIVIYO Smart Ring Health & Fitness Tracker — Matte Black, Slim 6.5mm, Sleep & SpO₂ Monitoring

This matte black, 6.5mm-profile smart ring combines continuous sleep and daytime tracking with on-demand workout logging and health trend insights in a lightweight design. It syncs faster for visible progress in the companion app, supports women’s cycle tracking and optional family health sharing, and comes in multiple US ring sizes—so checking the size chart before ordering is important.

How accurate are VIVIYO’s measurements for daily use?

The ring collects optical and motion data to estimate heart rate, HRV, blood oxygen (SpO₂), stress trends, and sleep stages. It’s built for consistent day-and-night wear to show patterns and progress rather than single-point medical diagnoses.

• Continuous heart rate and HRV monitoring for trend tracking.
• SpO₂ readings to observe overnight and daytime oxygen trends.
• Sleep staging (deep, light, awake) plus nap detection for better sleep insight.
• Produces app-friendly charts and history for weekly and monthly review.

What workout and sports features does the ring support?

VIVIYO supports over 180 sports modes for both app-driven GPS workouts and device-only sessions that don’t require your phone. It can automatically record common activities and organizes session summaries inside the app so you can compare performance over time.

• 180+ built-in sports modes including running, cycling, yoga, and strength training.
• App Workouts use phone GPS for pace and route mapping.
• Device Workouts allow phone-free tracking and automatic session logging.
• Clear activity history and progress indicators in the companion app.

How comfortable and practical is the ring for everyday wear?

The ring is designed with a slim 6.5mm profile and a lightweight construction to be worn around the clock, including while sleeping. No subscription is required, and the ring’s form factor minimizes interference with daily tasks and workouts.

• Slim 6.5mm thickness for low-profile all-day wear.
• Lightweight build suitable for sleep, work, and exercise.
• No subscription fees—one-time device use with app access.
• Clear size chart and measuring guide recommended before purchase.

What family and women’s health features are included?

The companion app offers menstrual cycle tracking and rhythm trend insights for women, plus Health Sharing to allow selected family members to view activity and shared data. These features are intended for tracking patterns and improving lifestyle choices rather than clinical diagnosis.

• Menstrual cycle tracking and personal rhythm overview.
• Health Sharing to connect selected family members’ activity data.
• Centralized app dashboard to view multiple health metrics together.
• Privacy controls for what gets shared and with whom.

Who is this for? The VIVIYO Smart Ring is aimed at people who want continuous, unobtrusive tracking of sleep, heart metrics, SpO₂, stress trends, and multi-sport activity logging without ongoing subscription costs. Choose this ring if you prefer a low-profile wearable that blends everyday comfort with broad fitness support, and make sure to select the correct US ring size using the included sizing guide before ordering.
