VIVIYO Smart Ring activity & health tracker — Matte Gold size 8, sleep, HR, SpO₂, 6.5mm slim

The VIVIYO Smart Ring is a slim wearable that tracks sleep, heart rate, HRV, SpO₂, stress, and 180+ sports modes without a subscription.

Lightweight and finished in matte gold, this size-8 smart ring is designed for around-the-clock wear: from sleep cycles and naps to phone-free workouts and family health sharing. It pairs with a clean app interface for faster syncs and visible progress, and its 6.5mm low-profile design aims to be comfortable day and night.

How accurate are the sleep and activity reports?

The ring records sleep stages (deep, light, awake) plus daytime naps and basic activity metrics like steps. While it provides clear trends and night-by-night comparisons, the data is intended for lifestyle tracking rather than clinical diagnosis.

• Tracks deep sleep, light sleep, and awake periods
• Logs daytime naps and total sleep duration
• Counts daily steps and records general activity patterns
• Syncs quickly so you can view results without delay

What biometric sensors does the ring monitor?

The VIVIYO ring measures resting and active heart rate, heart-rate variability (HRV), and blood-oxygen saturation (SpO₂), plus stress indicators calculated from those signals. Results appear in the app with simple graphs and trend summaries for short- and long-term monitoring.

• Continuous heart rate tracking for day and night
• HRV readings to show variability trends
• SpO₂ checks to monitor blood-oxygen directionally
• Stress estimations based on combined biometrics

Can I use the ring for workouts and outdoor training?

Yes — choose from over 180 sports modes that support both phone-free device workouts and app-based sessions with GPS for outdoor activities. The ring will automatically log many workouts, keeping your exercise history organized in one app.

• 180+ sports modes for running, cycling, swimming, and more
• Device Workouts for phone-free tracking during sessions
• App Workouts provide GPS routes and pace for outdoor training
• Automatic workout detection and clear activity records

• Optional Health Sharing to share data with trusted family members
