The ZBNMY Smart Ring is a lightweight, subscription-free wearable that tracks heart rate, blood oxygen, sleep stages and daily activity while offering up to seven days of battery life and IP68 water resistance.

Designed for both men and women, this silver-size-9 smart ring combines continuous health monitoring with activity tracking in a discreet metal form factor. It pairs with a free Android/iOS app (no subscription required) for trend views, remote photo control and simple sharing with friends or family. The package includes a portable 500 mAh charging case for on-the-go top-ups and a size guide to help you pick the most secure fit.

How accurate is the ring for everyday heart rate and blood oxygen monitoring?

The ZBNMY ring records heart rate and blood oxygen around the clock to give you a continuous snapshot of daily metrics. It’s designed for wellness insights rather than clinical diagnosis and is best used to spot trends over time.

• 24/7 heart rate tracking for resting and active periods
• SpO2 (blood oxygen) readings available through the app
• Trend charts in the app to compare day-to-day and week-to-week data
• Not a medical device—consult a professional for clinical evaluation

What sleep data does the ZBNMY Smart Ring collect and how will it help me?

The ring automatically tracks sleep stages—deep, light, REM/eye movement phases—and wake periods to summarize nightly sleep quality. Use the app’s reports to identify patterns and adjust bedtime, environment, or habits to improve rest.

• Automatic detection of sleep duration and sleep stage breakdown
• Wakefulness logging to show interruptions or restless periods
• Nightly summaries and longer-term sleep trend reports in the app
• Actionable insights for lifestyle adjustments, not medical treatment

How long does the battery last and what charging options are included?

A single charge replenishes the ring in about 1–2 hours and supports 5–7 days of typical use, depending on monitoring frequency. The included portable charging case adds convenience for travel, extending usable time between mains charging.

• 1–2 hour charge time for the ring itself
• 5–7 days typical battery life per full charge
• 500 mAh portable charging case included for multiple recharges
• Compact case designed for travel and daily carry

Is the ring suitable for swimming, workouts and daily wear?

The ZBNMY Smart Ring has IP68 waterproofing, making it safe for hand washing, showers and shallow swimming sessions. Its durable finish and lightweight profile are intended for continuous wear through typical daily activities and most fitness sessions.

• IP68 rating for protection during water exposure and sweat
• Low-profile, metal construction for comfort during exercise
• Activity tracking for steps, distance and calories burned
• Multiple sport modes supported via the companion app

Who is this for: The ZBNMY Smart Ring is built for people who want a compact, discreet tracker that fits like jewelry but records comprehensive daily wellness data. It appeals to travelers and professionals who value long battery life and a portable charging case, couples or friends who want to share health trends, and anyone seeking a subscription-free wearable that emphasizes trend monitoring, sleep insight and basic activity metrics rather than medical-grade diagnostics.
