VIVIYO Smart Ring Fitness & Health Tracker — Matte Gold, Slim 6.5mm, Sleep, HR & SpO₂

The VIVIYO Smart Ring is a slim, all-day wearable that tracks sleep, heart rate, HRV, SpO₂, stress, and more while supporting 180+ sports modes and women's health features.

Designed to sit comfortably on your finger, the VIVIYO Smart Ring combines continuous biometric sensing with a lightweight 6.5mm profile so you can wear it through sleep, workouts, and everyday life. It syncs data to a companion app for clear progress updates, supports family health sharing, and includes menstrual-cycle tracking tools — all without a subscription. Before ordering, confirm your US ring size using the included measuring guide to ensure an accurate fit and consistent sensor contact.

How accurate are the heart rate, HRV, and SpO₂ readings?

The VIVIYO Smart Ring uses optical sensors to deliver continuous heart-rate monitoring, HRV trends, and blood-oxygen (SpO₂) estimates throughout the day and night. While wrist- and ring-based optical measurements are strong for trend-tracking and daily insights, they are not a replacement for clinical devices. Expect consistent trend data suitable for activity tracking, recovery awareness, and general wellness monitoring.

• Continuous heart-rate monitoring for day and night trends
• HRV readings to show variability and recovery patterns
• SpO₂ estimates for overnight or on-demand oxygen-level trends
• Visible sync confirmations to know when data has updated

Can I wear the ring while sleeping and exercising?

Yes — the VIVIYO Smart Ring's slim 6.5mm profile and lightweight build are intended for comfortable round-the-clock wear. It records sleep stages (deep, light, awake) and daytime naps while also automatically logging workouts across many activity modes. The design minimizes bulk so you can keep it on through cardio, strength training, and rest periods without discomfort.

• All-night sleep detection including sleep-stage breakdown
• Automatic workout detection plus manual device or app workouts
• 180+ sports modes for indoor and outdoor activities
• Comfort-first 6.5mm thickness for uninterrupted wear

What training and tracking features does the app provide?

The VIVIYO app centralizes activity history, workout summaries, and health metrics with fast syncing and clear progress indicators. App-based workouts can leverage your phone's GPS for outdoor tracking, while device-only workouts let you train phone-free and sync results afterward. Health Sharing enables selected family members to view shared metrics for collaborative monitoring and motivation.

• App Workouts with GPS-based outdoor tracking
• Device Workouts for phone-free exercise sessions
• Organized activity logs and workout summaries in one view
• Health Sharing to connect data with family members

How do I pick the right ring size and set it up?

Choosing the correct US ring size before purchase is important to keep sensors in proper contact with skin and ensure accurate readings. Use the provided measuring guide and the size chart image included with the product to determine your size. Once you have the ring, pair it with the VIVIYO app, follow the on-screen guidance for sensor placement, and allow the ring to sync fully so data begins flowing to your dashboard.

• Check the detailed size chart and measuring guide before ordering
• Proper fit improves sensor contact and measurement reliability
• Simple app pairing and step-by-step setup instructions
• No subscription—just pair, sync, and start tracking

It's ideal for active users who want detailed sport-mode options, people tracking sleep and recovery trends, and families who appreciate shared health data and women who want menstrual-cycle tracking.
