Smart Ring Health & Fitness Tracker for Men and Women, Sleep and Activity Tracking, HRV and Stress, Heart Rate and SPO₂, Women Health Support, 120+ Sports Modes (Matte Gold, 8)

Quick take

This VIVIYO smart ring focuses on daily sleep and activity tracking, with heart rate, SpO₂, HRV, and stress monitoring you can review in a companion app. It also covers 120+ sports modes (including phone-free workouts) and includes women’s health features like menstrual cycle tracking and optional health sharing. The main buying caveat is size, so verify the sizing guide before you order.

Pros and cons

Pros

  • Sleep breakdown and day activity tracking in a lightweight, slim 6.5mm profile for all-day and all-night wear.
  • Health metrics include heart rate, SpO₂, HRV, and stress monitoring.
  • Supports 180+ sports modes, with app-based GPS workouts and device-based phone-free sessions.
  • Women’s features include menstrual cycle tracking and health sharing for selected family members in one connected app.

Cons

  • Fit matters, and incorrect sizing can make the ring uncomfortable or less effective for consistent wear.
  • Review evidence is limited, so real-world claims about accuracy and battery performance are not fully proven across the full range of users.

What buyers think

Reviewed productBuy on Amazon

Buyer feedback is generally positive around setup simplicity, comfortable fit, and the ring’s thinner look compared with many smart rings. Several users mention that sleep and fitness tracking aligns well with what they already track on a smartwatch, and multiple reviews highlight good battery life and a satisfying appearance. The overall review volume is still moderate, so buyer-review evidence is most reliable for usability and comfort themes rather than for fine-grained performance guarantees.

Key features that matter day to day

Sleep and activity tracking

This smart ring is built to record your nightly sleep stages (deep sleep, light sleep, and awake time) and also track daytime activity, including step counting. If you want one wearable that can stay on through sleep and continue logging your movement during the day, the “ring-first” design is the point.

Heart rate, SpO₂, HRV, and stress

For health-focused tracking, it monitors heart rate and blood oxygen (SpO₂). It also provides HRV and a stress metric, meant to help you understand how your body is responding across your routines.

Sports modes for structured training

Workout tracking is a major selling point, with 180+ sports modes. There are two ways to log sessions: app workouts for outdoor tracking that uses smartphone GPS, and device workouts that allow phone-free sessions. For people who alternate between casual movement and planned training, this flexibility can reduce friction.

Women’s health support and health sharing

In addition to general fitness and sleep metrics, the ring includes menstrual cycle tracking and rhythm trends. It also supports “health sharing,” allowing selected family members to view shared daily activity and health data in one connected app. If you want shared accountability or family visibility around wellness routines, this is a differentiator to consider.

Pros and cons, translated into buying guidance

Who it’s a good fit for

  • You want sleep and everyday activity tracking in a slim smart ring design, rather than a bulkier watch.
  • You care about HR-related metrics (heart rate, SpO₂, HRV, stress) alongside fitness basics like steps.
  • You train across different sports and want many activity types supported, including options for workouts with or without your phone.
  • You’re interested in women’s health features like cycle tracking, or you want a shared-view option for family members.

Who should think twice

  • If you’re not confident in your ring sizing, don’t skip the sizing and measuring guidance. Smart rings rely on consistent, comfortable contact.
  • If you need extensive third-party verification for metrics accuracy, or you only trust very large review datasets, consider widening your comparison to other models with stronger public testing coverage.

Setup and app experience

Reviewed productBuy on Amazon

Feedback points to an easy setup process, and buyers repeatedly mention the ring fit correctly. The app is designed to provide clear progress and quick syncing, with the goal of reducing long loading waits when you check your latest health and activity stats.

Battery and wear considerations

Buyers mention good battery life and comfortable all-day, all-night wear. As with any wearable, real battery performance can vary based on how often you use sports modes and how frequently you sync data, but the comfort and daily habit fit are themes in the available review evidence.

Comfort, durability, and water resistance

The ring is described as waterproof up to 50 meters and rated IP68, which is a practical baseline for everyday exposure. It’s also designed to be slim (6.5mm) to help reduce the “bulky ring” problem that can interfere with sleep or workouts.

Price and availability

Reviewed productBuy on Amazon

Pricing changes over time, so it’s worth checking the current listing to see where it lands versus your budget and competing smart rings. You can also compare your target features, like sports mode depth, HRV and stress tracking, and women’s health support, to avoid paying for extras you will not use.

Verdict

The VIVIYO smart ring is a strong choice if you want a slim, comfortable ring for sleep and daily activity tracking, plus HRV and stress style insights and SpO₂ monitoring. It’s especially compelling if women’s cycle tracking and health sharing matter to you, and if you want many sports modes with both phone-based GPS workouts and phone-free device workouts. Just prioritize correct sizing, since fit is the make-or-break factor for smart rings.
