Benio Ring Gen 2 Smart Ring - Advanced Sleep & 24/7 Health Tracker

In this review the Benio Ring Gen 2 smart ring is evaluated for people who want discreet, continuous health tracking without a bulky wrist device. The biggest reason to consider it is the combination of an advanced sleep tracker and round-the-clock monitoring of heart rate and SpO2 in a small, waterproof form factor, making it ideal for sleepers and active users who prefer minimal hardware. The ring pairs with a phone app, carries no subscription fee, and aims to be comfortable enough to wear day and night.

Key Features

• Size guidance: The product emphasizes checking the size chart and measuring your finger before buying to ensure a comfortable fit and avoid returns.
• Advanced sleep tracking: It automatically records REM, light, and deep sleep stages so users can see detailed nightly patterns and improve rest.
• 24/7 health monitoring: The ring continuously logs heart rate, SpO2, steps, and calories so daily activity and health trends are easy to review.
• Multiple workout modes: Built-in tracking supports activities such as running, cycling, hiking, yoga, and golf for clearer fitness progress.
• 5ATM water resistance: A fully sealed design allows swimming, showering, and exercise without removing the ring.
• No subscription required: Data syncs to the companion app with no ongoing fees and includes a 1-year free replacement policy and lifetime support.

Who It's For

The Benio Ring Gen 2 suits people who want a compact, unobtrusive health tracker that doubles as jewelry and who value sleep and SpO2 monitoring over smartwatch features like apps or large displays. It is especially useful for those who swim or shower frequently because of its 5ATM rating, and for anyone wanting continuous heart rate data without a wristband.

Those who should look elsewhere include users who need smartwatch notifications, third-party app ecosystems, or medical-grade devices for clinical diagnosis. Also, buyers who are unsure about ring sizing or who prefer adjustable bands may find a ring format limiting.
