BENIO Smart Ring Gen 2 — Heart Rate & SpO₂ Tracker

Designed for both women and men, the BENIO Gen 2 combines discreet style with multi-day battery life and automated fitness tracking. Lightweight and low-profile, it captures 24/7 biometric data—heart rate, SpO₂, steps, calories, distance—and recognizes workouts automatically while syncing to iOS and Android via the companion app. The ring’s sealed 5ATM construction makes it suitable for pools, showers, and everyday wear.

How accurate are BENIO Gen 2’s health and sleep readings?

The Gen 2 uses optical sensors and algorithms to estimate heart rate, blood oxygen, and sleep stages throughout the day and night. While it provides useful trends and nightly breakdowns, it’s not a medical device—use it for lifestyle and fitness insights rather than clinical diagnosis.

• Continuous heart rate monitoring with resting and active trends
• SpO₂ measurements for overnight and on-demand checks
• Sleep staging including REM, deep, and light phases
• Automatic sleep detection and consolidated nightly reports

What activity tracking and sports modes does the ring support?

BENIO Gen 2 automatically detects common activities and supports multiple sport modes for intentional workouts. It logs steps, calories, distance and time, and pairs heart rate data with route and duration for clearer progress tracking in the app.

• Auto-recognition for walking, running, cycling, hiking, and more
• Workout metrics: time, heart rate zones, calories, and distance
• GPS route import via phone when paired during outdoor sessions
• Activity history and weekly summaries in the companion app

How durable is the BENIO Gen 2 and what is battery life like?

The ring’s fully sealed housing and 5ATM rating make it resistant to water exposure for everyday use and swims. A single 1–2 hour charge delivers multiple days of active monitoring, minimizing interruptions to your routine.

• 5ATM water resistance—safe for pools and showers
• 3–5 days of typical use per charge depending on sensors and activity
• Quick top-up charging in about 1–2 hours
• Bluetooth syncs data to iOS 9.0+/Android 5.0+ devices—no subscription required

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

Because fit influences comfort and sensor accuracy, BENIO recommends trying a sizing kit before buying. If you skip the kit, measure finger circumference and consult the size chart to pick a snug, secure fit that won’t slip during activities.

• Optional sizing kit available to test sizes at home
• Measure finger circumference for a stable, comfortable fit
• Pair with the BENIO companion app for step-by-step setup and calibration
• Includes charging cradle and quick-start guidance in the box

Who is this for? The BENIO Gen 2 Smart Ring is ideal for people who want continuous biometric insights in a minimalist form—fitness enthusiasts, busy professionals tracking sleep and stress trends, swimmers or frequent hand-washers who need water resistance, and gift shoppers seeking a wearable without recurring fees. It fits those who prefer unobtrusive technology that blends with everyday jewelry while delivering health and activity data to their phone.
